This is a good example of having correct information and a logical diagnostic process being absolutely necessary in this field. I sometimes reflect on past cases and see if I could have taken a different approach to get to the conclusion faster.
I wasn’t able to get that fault code until close to the end & then I believed I created it disconnecting things. This was a good learning curve for me Ian. Thanks mate 🙏🙏
Ohh Peter a man after my own heart just keep going and going i used to work in a hgv workshop and let me tell you the Isuzu lorries are famous for cam sensors doing exactly this if it doesn’t see cam it doesn’t know when to inject fuel hence the injectors not opening and if it doesn’t know the positio of cam it’ll disable crank as they need to be synchronised to allow the ecu to calculate the signal I’ve been down this exact road with a Isuzu n series lorry and much like you it took me a decade to figure out what was happening I was coming in on Sundays to get to the bottom of it pain in the bottom well done though getting to it a pure legend luv it lol
I think we all endure the same old tasks & boy gods a fella have to have a lot of grit to drive on even though failing miserably at times 😤😤 I love your comment it made me smile on a Tuesday morning, thank you David 🙏🙏🙏👍
I wasn’t very happy with the format it took from start to finish hense never making it public. There was so much I should have done differently but you learn something new everyday 😬. Age is a great thing Dave as we spoke about. But thanks anyway Dave 🙏
I couldn’t figure out why my fuel pressure was so high & the scantool wasn’t seeing engine speed. It all sounds simple when you say it t like that, but unfortunately I didn’t see it at the time. Delighted to get a result though 🙏🙏👍
Fantastic Peter that was like a good book I couldn’t put it down. That would have been an unfixable car at most places you have my admiration and I certainly learned a thing or two there.
I learned a thing or 2 also and oh boy how diagrams & scantools can lead you down the garden path. I’m really glad you liked it as I have it recorded with 2 years or so & thought it wasn’t great, thanks Kevin 🙏🙏🙏👍
I've seen a few of these cam signal failures. Mostly from water getting into the connector. On the early 4JJ1 the cam and crank sensor are the same part
Bloody stupid cars, I should have just put petrol in it 😂😂😂😂 Hindsight is a great thing & I should have seen the cam sensor being held at 2.5v rather than 5v. Every day something to be learnt 🤔🤔🤔 Cheers Gav 🙏🙏
@@kennedysgarage3281 It turned out to be the camshaft sensor and the crank angle sensor behind the starter both had died, I now have to replace the biometric atmosphere sensor, code p2227 and hopefully it should be good to go but I got alot from your video, cheers
Cryckies Peter that was a marathon session…4 weeks!! - I know ye weren’t on it all day every day..but I bet in your head ye were. Some serious diagnostics going on between the two videos and wise to have as many heads as possible on it..Sometimes we can get so focused on just that one rabbit hole.. Fair play for the perseverance..certainly not an easy or clear one by any means. For the majority I suspect this wagon could have been signed off to the scrap. Your videos are so insightful and helpful Peter..what you demonstrate can be applied to any car and diagnostics of sensors etc. Keep up the educational work - its very much appreciated 👍🏻 Maybe time for a rebranding…: Kennedys Auto University-Where the learning never stops 😊
Thank you so much for that Damien, I really do appreciate it. But you’ll be giving me a big head 🙂🙂 In hind sight I should have noticed the 200,000kpa fuel pressure being too high at the start, but only for the encounter I probably wouldn’t have known or realised that the injectors not opening would have caused it 😤 Something to learned everyday 🙏🙏
Scope that camshaft position sensor, you should have 5v feed, an earth/ground & a 0v to 5v square wave sign. It was only rising to 2.5v in my cause . Good luck with it 🤞🤞🤞
Working on a customers 88 RS turbo escort right now.. Not a computer in sight Peter. TBTG. :-) I just have to figure out the rust. Rather you than me ^^.

Hello sir I've got the same case with crank no start , Have done what ever can be done humanly But no rpm is being seen on the fault scanner and even no fault codes 3 wire sensors cam and crank jave got 1 ground and 5v ref on two wires
This is an old video Russell & I wasn’t going to make it public, then this morning I thought why not. Hindsight is a great yoke. In the first 2 minutes of watching it back the 200,000 kpa fuel pressure should have made me think long and hard 🤷🏼♂️👍👍👍
I’ll have to google Asynchronous just for educational purposes 😂😂 I have heard of it but still haven’t a clue what it means 😬😬 I’ll let you know how I get on 😉
I only know it thanks to electric motors ie asynchronous motor and synchronous motors on hybrid and electric vehicles same goes for tyres you’ve got symmetrical and asymmetrical lol I know that from carrying out mots we have to sit a test every year and that question comes up every bloody year haha
Hi Peter, I have the exact same issue as you. No engine speed, excessively high fuel pressure (200000kPA) , P0340 error and crank no start. Unfortunately for me changing the cam position sensor did not solve it. Mine happened after someone washed the engine bay with a pressure washer. Any advice?
For those with similar problem, the fix was to change the Cam Shaft position sensor AND reset the codes. Changing the sensor alone did not fix the issue with my 2017 Isuzu Dmax 3.0.
Common fault on this vehicle. Most of the time it will happen when engine is hot. Always fails the same way where it can not pull down the signal to 0v. The crank sensor fails in the same way but the difference is the vehicle will still start but will be in limp. So in short these 4jj1 engines can run with only cam but not with only crank sensor.
I think we all learnt a few things from that ordeal Peter. I admire your perseverance. Well done!
In the wind up Trevor I didn’t know what to believe, scan tools & diagrams leading me around in a circle 🙂😂😂😂
So well done Peter. Great to finally track down the problem.
It was a challenge Michael & I was delighted to eventually get to the end of the issue 🙏🙏👍
A great Cartoon, Peter.
An ‘old’ bit of Paddy’s day entertainment 😉😉
This is a good example of having correct information and a logical diagnostic process being absolutely necessary in this field. I sometimes reflect on past cases and see if I could have taken a different approach to get to the conclusion faster.
Absolutely correct, the necessity for accurate information & scantool feedback is vital and really can lead you so far astray if incorrect 😤👍👍
Yes Peter, P0340 Camshaft Position Sensor Circuit ,(current Malfunction)Brilliant case study ,watched every second of the Video"s👍👍

Great diag Pete, it's always a new day in our trade help is massive even to the best techs, always something

Crank no start...me every Monday morning.
I’m getting the same 😬😂😂😂

Great video I am currently in the exact same situation thanks for the info cheers.
Did a camshaft sensor sort it ???

Another great video 👍🏻 Exact same non start symptoms on a 2014 2.5 DMax. No fault codes though

Hello sir
I've got a same case
Crank no start
But i do have a ground and 5v ref in two wires
No rpm being shown in the live data @@kennedysgarage3281

You did watch it, well done mate. Bloody camshaft signal range 🤷🏼♂️🤷🏼♂️🤷🏼♂️🤷🏼♂️
Something new to be learned everyday, cheers Ronald 🙏🙏
Hence the term asynchronous ie not in time with or at a different interval absolute nightmare of a job my boy lol
I’ll have to google Asynchronous just for educational purposes 😂😂
I have heard of it but still haven’t a clue what it means 😬😬
I’ll let you know how I get on 😉
I only know it thanks to electric motors ie asynchronous motor and synchronous motors on hybrid and electric vehicles same goes for tyres you’ve got symmetrical and asymmetrical lol I know that from carrying out mots we have to sit a test every year and that question comes up every bloody year haha

What a nightmare to think that a simple sensor could leave you stranded in the middle of no were not a great design.
I actually never thought of that, it is funny that they haven’t a default strategy that went back to the crank signal only 🤔🤔
Thanks Vincent 🙏🙏👍
That’s messed up 🤯
I was glad to see the end of that 😂😂😂🙏
