Timing chain mystery

Post by Electrotoucan » Tue Sep 15, 2020 9:56 pm

Hi to all
I recently helped a mate change his timing chain on a 2.2 Transit.The noise it was making was unbelievable and after getting the front cover off it was carnage.The tensioner was still present although in its maximum setting.The whole of the large guide opposite was smashed to pieces and in the sump.Infact the chain was eating away at the aluminium posts left behind.The smaller guide between the rh cam sprocket and pump sprocket was nearly gone.Oil pump chain tensioner completely loose missing its spring leaf!
How the chain didn’t jump is pure luck.Checked timing and it hadn’t.Well anyway after new chain kit and pump we’ve got it running quieter than ever.The problem is a p1174 code (cam sensor) has come up and the esp light is on.Ive done a sync check,
Engine stationery reads -no
Engine running reads-yes
So that seems ok.
Pulled out cam sensor(was covered in gunk)tried another unit,same problem .
Any advise would be much appreciated .

You may have to perform a crank timing learn in the PCM.

I've not done one personally but hopefully someone will chime in.

Cam and Crank out of Faze maybe one tooth check alignment have come across this many times :shock:

Thanks for that info.It makes sense that pcm was probably adjusting the timing to compensate for the chain stretch.It now may need resetting from scratch.Im guessing but I will continue raking through the internet to be sure.

Thanks Fraze although I can definitely say it’s correct on the chain.The crank was locked off with a tool on its damper mounting face but I also locked in through to the flywheel where the crank sensor is,just to check.

Just come across this..

If you are seeing repeated cam sensor dtcs (range or performance) in particular . Worth noting on the ford continetal transits ,rangers etc the code will repeatedly flag until pcm learned values have been reset.
