Mobile Mechanic - 2017 Chrysler Pacifica - P018C Fuel Pressure Sensor Circuit Low
Вставка
- Опубліковано 5 жов 2024
- I had a customer's van show a P018C Check Engine Light code and discovered the fix was to replace the Fuel Pressure Sensor which is inline on a fuel hose. Part # 52030445AA is no longer available, so you now need to order 68421782AA and 68137864AC. The 2nd part is a new wire harness. Apparently they discontinued the fuel pressure sensor originally used, and now there is a different one. You might be able to still find and order the older, discontinued style online which would be plug and play, but the newer, replacement style requires you to splice in a new harness and I show you how to do that. Feel free to ask any questions and I'll get back to you as soon as I can. Thanks!
This is a link to the exact procedure I shared above: static.nhtsa.g...
Use A flat head screw driver when installing intake clip to help push it all the way in if needed. Thanks for the vid.
Good tip. You're welcome!
This video is extremely invaluable. Thank you to guys like you who take the time and share your experience and solution to common issues like these.
Two years later, what's the update? Would be awesome if you could let us know how things are going since the fix? Thank you!
You're welcome! I'm glad you found it invaluable!
This customer actually recently sold this van, but the issue never came back in that timeframe. He bought a Kia Carnival instead.
To remove the fuel hose, you need to separate the legs of the red/blue clip from below (you may not be able to see them) and then it should unlock and slide away from the hose. The white clip legs are then free to expand and separate when you try to pull the hose off. Neither the red or white clips need to be completely removed from the fuel hose.
Thanks for the tips! It can be tricky.
Thank you for posting this video. I had to make the exact same repair today and was stuck on how the wire pins installed into the new connector. No instructions and I would have never been able to figure out the red "lever" on the connector. Much appreciated! My CEL is now gone.
You're welcome! I had to do a decent amount of research before I accepted this job because I couldn't find any videos on the Pacifica, but I found a pretty good forum thread that described the procedure. I'm glad I was able to help and your CEL is now gone! Good work!
@@mjspiess Same thing here! I fought that stupid connector for hours trying to get it to fully seat and this video finally got me going again. Thanks for saving me $400 from the stealership!
@@eugeneyoo3089 You're welcome!
Thanks for the video! Missed some of the detail with the camera aimed off center but still very helpful.
You're welcome! I was experimenting with a body cam and it wasn't quite what I wanted for the reasons you pointed out.
TLDR: if you don’t hear two clicks when reinstalling the tube try lubing the lip it needs to go over.
Just had to do this repair myself, having never worked on a car before, since the two different men who said they could take care of it were no shows. The clip going toward the back of car definitely did not click. I did feel it go past the lip, but no locking. I started the car and no fuel was leaking so I assumed it was fine. But I had a very bad feeling that that might not be the case if driving the car around. The next day I started the car again to confirm my fear and fuel was now spraying every where.
You don’t really need a tool to get this part on right. Turns out the fuel helped to lubricate the lip and after that and a two handed effort (one hand on each part pushing together rather than just pushing it from one end) it locked on. It’s TWO clicks you want to hear.
It sounds like you had quite the adventure with that car repair! It's impressive that you managed to figure it out, especially without prior experience. Your tip about listening for the two clicks and using fuel as a lubricant is really practical. Thanks for the feedback.
Thanks for the video! I was surprised to have this happen on a 2017 vehicle with only 23,000 miles. The only snag I ran into was not realizing there were TWO clips that needed to come off the engine side connection - a blue clip (upper) and the white clip (lower) I finally figured it out when I got a flashlight down in there - then the section of the video where you show the white clip made sense to me. I used the white/yellow wires in the kit only - it is easier to splice the smaller wires (18ga) to the small 22ga wires feeding the old connector. Also, recommend using long splice solder connections, and not the cheesy crimp terminals in the kit. Make the individual splices about 2 inches from each other so there is no danger of ever shorting, and cover the long splices with 1/8" marine shrink tubing (available at Harbor Freight). Don't try to use the gargantuan shrink tube supplied in the kit! It won't shrink enough onto these small wires! I wasn't sure if the code would clear by itself when I was done (it did!). Amen!
You're welcome! Wow... That is surprising! I believe this one had only around 50k miles. Thanks for your tips!
That's Chrysler for you. My wife's Pacifica just got this code on 46k miles Pac Hybrid.
Many thanks for posting the link to the repair documents. I have access to prodemand could not find any TSB's or how to wire the new plug. The parts guy was no help either.
You're welcome!
I did this two years ago now I’m getting P018D circuit high
This code typically points to problems in the wiring. I would guess your original spice job may have come loose or got corroded.
Inspect the wiring harness and connectors related to the fuel pressure sensor. Look for loose connections, damaged wiring, or corroded connector pins. If any issues are found, repair them as necessary.

You push the white clip in. Pop up the outdated blue clip, push the white clip in. To reinstall, push the white clip in and then push the red clip down to lock the white clip in place..
Thanks for the tip!
Thank you for the video! 🤘🇺🇸
You're welcome!
awesome vid, thanks!
You're welcome!
It'd be cool if your cameral actually pointed at what you were working on...
I know. I was experimenting with it and realized afterward, it's just not going to cut it with that angle.
Thank you for the great video, minus the dead camera battery at the end. One question though. The spec sheet you linked to in the end talks about making sure the length of the wires are approximately the same but the process you followed seemed like it was lengthening the wires by a foot or more. What did you do with the extra length of wire you used? thanks again.
You're welcome. I did make the wires longer. I figured I'd rather have excess vs not enough, so I folded the wires and zip tied the excess bundle along side another wire loom I think.
Hopefully this thread is still live. Thank you for the video. Ironically for me, I never got a sensor code, rather I had a pinhole in the tube that was squirting gas. Replaced tube/sensor and spliced in new harness with oem parts per the video. Now I get a P018D code. Code Didn’t clear with obd scan tool. But, when I start the car after clearing, check engine light goes off - drive for 20 mi at varyimg speeds, car runs fine and light never comes back on. Turn car off, back on, check engine light back. Tried shortening the wires but still throwing the p018D code. Any ideas?
You're welcome! Hmmm, that is very strange. Potentially a faulty sensor assuming the wires are correctly oriented? Sorry! I wish I could help more!
Thanks for replying.
But, if it were a faulty sensor, wouldn’t it throw a different code - not the 18D?
@@RayBroderick-lg7vb good point. I found this: www.pacificaforums.com/threads/error-code-p018d-chrysler-fuel-pressure-sensor-b-circuit-high.48449/ Maybe double or triple check your wiring?
Thank you, you’ve been incredibly kind to keep replying. Turns out, I screwed up (as you were probably guessing). When I was inserting pins, I pulled up on that red tab. Unfortunately, the red tab was already up when I started. I guess in doing so, I broke it bc it apparently wasn’t locking the pins in correctly. A $95 lesson. Thanks again for the video and kindness. Much appreciated.
Does anyone know if it's the same for a hybrid same year and model?
I want it also
Can you post the duagram?
This is a link to the exact procedure I shared above: static.nhtsa.gov/odi/tsbs/2020/MC-10180205-9999.pdf
Can you show the actual wire colors and how they are connected? I'm having the same problem.
I can't remember off hand what the actual wire colors were, but they are just splice together.
My mom has a 04 chrysler pacifica. I've been doing some long overdue maintenance and replacing some things on it. In the process I found out that this fuel filter in non serviceable. Would it be a good idea to install a in line fuel filter?
It probably wouldn't hurt to install an inline fuel filter, but Chrysler didn't seem to think it was necessary, so I'm not sure if it would be worth the trouble?
Quick question did you use the golden clamps on the splicing or did you just soldered it? And heat shrink?
I soldered and used heat shrink.
@@mjspiess i couldnt get the connection on the engine side to click did i do something wrong or are their different size connections?
@@eliuttgonzalez2003 Could you please clarify? There are 2 ends of the hose and the wire harness. Are you talking about the end near the oil fill area? You may not get an audible or tangible click, but as long as it doesn't pull off, it should be secure. You might need to fiddle with the built in securing clip.
@@mjspiess yess sir because the one on the back left on engine slides behind the ring and clicks but the commection on the engine side by the oil doesnt go all the way throu and red clip only goes half way down i could forecebly move the white tabs to the side to fully close the clip but fuel connection slides out amd spills gas
@@eliuttgonzalez2003 It is tricky, but to reinstall, push the white clip in, slide the end onto the fitting and then push the red clip down to lock the white clip in place and it should stay put.
I am having the same issue with my 2017 Pacifica. However, when I look it up online, mopar has the part for sale but it doesn’t say anything about needing to splice a new connector in or anything. The auto store said that they can’t order it and I would have to go through the dealership to get it fixed. I just don’t know if I will need the connector or if it will plug right in. Do you know if there is a way to tell before I order it?
As far as I know, the only part that will plug right in is no longer available (52030445AA). If the part # is 68421782AA, then it requires the additional harness that needs spliced in (68137864AC). When I ordered mine through the dealership I think their software bundled the two since they are both required to get it to work.
How do you reset the check engine light after you install the new FPS?
I used my OBD MX+ bluetooth dongle scan tool.
Hello. T&C 2015. Where to find the TPMS module? It is not above the left rear wheel.
From the factory manual: "The TPM is located in the left rear wheel well behind the splash shield and is mounted to the wheel house inner flange with a bracket." This post shows a picture of it on a 2012. They may have changed the location later, but doubtful:

@@mjspiess Thank you for your answer. I saw this link. However, the location of the module has probably changed. So the module can be practically anywhere
@@romankubiak150 I'm sorry to hear that. That is incredibly frustrating. Hopefully you find it sooner than later!
Content good! Camera work not so good! Way to dark, and never in the correct spot. It should be on your head so we see what you are looking at. When you brought the fuse cover into the sun it was clear as a bell! Turn the car around so the sun is in the engine bay!!!! Thanks for the info
Thanks for the tips. I have a head mount and will experiment with it instead of the body mount. It's definitely nice to have a hand free option and I appreciate the feedback.
Yeah, you left the frame completely when changing the harness connectors... this video was almost helpful
How do I fix code po0206 for a fuel Injector? :(
P0206 is usually caused by a bad fuel injector or wiring issue, so it would require you to evaluate the wiring to that injector and if it's good, then likely will need to replace the fuel injector.
Do you know where to get the original sensor for the same vehicle?
Maybe eBay on occasion. From what I gathered, since it has been discontinued, you're not likely to find it very easily anymore.
@Asmodeios Possibly. I had a really hard time finding struts for this same Pacifica. The driver side was already knocking over bumps after only 50k miles...
@Asmodeios Wow! That's pretty awesome on the 17 and 18! That's really unfortunate on the 20 hybrid though. I love my Volt and was hopeful the Pacifica Plug-in Hybrid was going to do well. Sorry to hear your mom is having so many issues with it.
Where can you buy the older PnP style?
If you google the original Part # 52030445AA, there are a lot of sources, but not the usual popular ones like Amazon, eBay, RockAuto, etc. The new part #s are 68421782AA and 68137864AC. The 2nd part is a new wire harness. They came together when I ordered this part from the dealership.
@@mjspiess I checked a number of sites. They have it listed for sale, but they don't actually have it available. Thank you for your video. We went the splice and solder method you show here with the new assembly. Pretty easy to do still... as long as you have the right tools. :)
@@uncle.lethal Thank you for letting us know! I think eBay had it available a couple months ago, but this customer needed it right away, so unfortunately, my only option was the dealership. You're welcome for the video. I'm glad it helped and gave you the confidence to tackle this repair.
