I had the timing chain replaced and it was full kit. Garage done the work. I noticed it sound a bit like it’s pulling back but thought it just needs to be bedded I and would be fine after a few days 100 miles. Now it’s been 375 miles still the same so checked on opcom to see any codes and comes up with cam sensor malfunction. So just had it replaced and is just the same. No codes until you go past 2t on revs and code comes up but it’s not setting off the ecu light. Engine is Z10xep 2004. Some site say it could be the crank sensor but that new march. Some say it could be the wiring or plug. But I’m wondering if the time is out on the sensor from the cam plate being set in wrong place. Says code present. No other codes. But I did think the temp sensor was playing up but that is new and wiggled the connection on it and it was and has been working properly since. Any ideas on this thanks

My guess is either timing phase disc set wrong or wrong spacer used. Pop the camcover off and see how much gap is between the cam sensor tip and the reluctor when. 2 to 3mm is what it should be. Any more and you will get cam codes

It looks like it in photos I’ve added. But it looks Like the gap is to big. But when I removed the sensor I put a rod in to measure from timing plate to outer shell and then measure the sensor length. And seams to be 6mm gap in differences. So think the gap is to large. ??

This is what the gap should look like. Your wheel needs spacing out further.

It’s sorted now 6mm washer sorted it out. No more code. Now has a 2.5mm gap. Garage did not know about the gap size. So now they know. Runs better even better at climbing hills thanks for your help
