Thank you for making this video! I found a frayed wire rubbing on my front differential (4wd) driveshaft under the drivers side door. I had code P0641, stabillatrak lights, also MAF and Crank Sensor codes. I believe the wire was running to the Fuel Tank Pressure sensor.
Just want to take the time to say your video was so helpful! My issues was a pinched wire with the oil filter cap!!! Had I not done the tug & pull method I would have never found it! God Bless You !
This video really helped me. I wasnt able to track down the shorted wire but when i unplugged the TPS sensor plug the p0641 code went away. i couldnt locate the bad wire cuz it was INSIDE the throttle body. I wouldnt have done that without watching this video. Thank you!
Thanks. Had same issue went followed everything down where you said exactly same problem. Two wires were worn through refixed them retaped everything and resecured the wires problems gone. Thanks dude
Guy had a P0641 , kept cutting out then run ok. Seen your post about the wire harness on left of engine. It quit in my driveway. I checked harness & sure enough the stud wore into a small gray wire. Repaired & all is good. 2007 Chevrolet 1500 2 wd pickup. Thank you!! 9:13
I’m getting p0641 and also a misfire. My oil pressure started to just not work. Would it be safe to say the sensor is bad and that’s what is causing these codes to turn up. It’s a suburban 2005
Most of the time its a shorted 5 volt reference wire that being shorted to ground. Yes, shorted oil pressure sensor can be the cause of the code and oil pressure gauge not working. Try following my steps from the video.
@@kevinhodges3374 To verify if it's a shorted sensor in that circuit or if it's a shorted 5v reference wire. The unplugging method should be done with a capable scanner that gives you the 5v reference data or you can use a volt meter connected to a 5v reference sensor signal for that circuit and watch your display to see if your voltage goes back up to 5v as you unplug each sensor one by one.
You may have faulty sensor for circuit 2. Try disconnecting the connector to each of the 3 sensor for circuit 2 one by one. Crank position sensor, Throttle position sensor and Accelerator position sensor and see if your code goes away or if your 5V reference comes back to normal.
@@EliTheOBDTech did all that all the way down to the tank for the fuel level sensor. An thing I also see happening not sure if that how this system work but on key on the fuel pump is running constantly.

Glad to hear that this video was helpful.
Got a 07 Escalade been having HELL with this car and o think you just saved me!! Had the same issue in the same spot!! Day 1 I’ll keep you updated
Sounds good.

Good to hear that this video gave you a guide 👍
Thanks man. Found wires rubbing on the front driveshaft
Thanks. Had same issue went followed everything down where you said exactly same problem. Two wires were worn through refixed them retaped everything and resecured the wires problems gone. Thanks dude
I'm glad it helped you
Amazing video. Exactly what was wrong with the truck I was working on.
Same issue here too! Thank you for getting rid of my headache! Suburban runs great!
Thank you for this video you're a life saver. Amazing discovery, well done. Thanks a lot

Thanks for sharing. Great video!!
Thanks for the video I have been pulling out hair trying to find the cause of the same problem I am having with my 2008 Silverado
Tankiu ur video was a life saver blessings
Thank you for the info. I was able to find the issue. Oil pressure sensor
I'm it helped, cheers.!
SAME PROBLEME IN MY TAHOE 2008 HYBRID . WITCH ONE PART I BEGIN TO TRY RESOLVE MY PROBLEME
What type of handheld device/ devices do you use?
I use many types of device brands. From Launch, Autel, Bosch, OTC, Mac, Matco, Autoboss, Injectronic and Snap-on.
How do you figure out what sensors are connected to the 5v circuit 1 having this code on my 2011 cts
Search your wire diagram up

If you unplug the connector from the sensor and P0641 goes away, then your problem is the sensor.
Thanks I will try that. 🙏🙏
5v most likely burn out wires
Did you see a spark at 4:30 ?
@@frank700se I did see a glare of light, not sure if it was spark
Hello what code reader do you have
I'm using the Launch X431 Pros Mini
What is the reason to unplug all sensors?
I’m chasing the 5v short 2009 Silverado 6.2, died last test drive when I turned

So if the short stays after unplugging the sensor than more than likely a wire is the problem.? Thank you
@@kevinhodges3374 Yes, that is correct
@@EliTheOBDTech how would I use the volt meter to find the shot in the 5v?
I have the code PO651. 🤔

Did most of your theory but still have low voltage
Do you have the same code?
Did you unplug all sensors pertaining to that 5 volt reference circuit?
@@EliTheOBDTech yes same code ran everything you did have all the sensors unplugged an still have low voltage
@@halspeedautoworkz764 Have you wiggle tested the engine harness in different points?
Hopefully is not your pcm going bad.

@@halspeedautoworkz764 It should not run constantly with key on engine off. It should only prime for 2 seconds and turn off.
What a dumb place to put those wires at.
Absolutely agree 100%
