Customer Question

Hi I've got a 04 x trail 2.2 dci the problem started when my local mechanic fitted a new scv and a new camshaft sensor the car now struggles to start has a massive loss of power smokes badly and won't idle I took it to my main Nissan dealer who said its the crankshaft sensor and the scv you've had fitted so they fitted both components and the car is exactly the same the car now is in another local garage the mechanic now thinks the timing chain has stretched and could be that he said there is conflict between the camshaft and crankshaft sensors the car will idle only with one or the other ???? Please could you shed light on this I'm £thou spent and no near to a soloution the car only has 70,000 mileage

hi there.

Welcome to

I hope i can be of help to you today.

I'm afraid i am inclined to agree with your lastest mechanic on this problem. I have seen it a few times now on the 2.2 diesel engine, granted though it has been in the primera, but this is the same engine. The timing chain guides actually wear and the chain stretches slightly so the camshaft sensor and the crankshaft sensor get mixed signals and think that top dead centre ( which is what the sensors are looking for) are in different places and so puts the car into limp mode. A diagnostic check would've brought up the fault of one of the sensors because the ecu thinks that one of the sensors is giving a false reading. Also when you remove the plug from the camshaft sensor it will run better but you will still be in limp mode.

Unfortunately for youself, the only thing you can do is get the chain and guides replaced. It is a very big job to do i will say. Probably about 8-9 hrs work because of the limited space and the amount of stripping needed to do the job. In essence the whole side of the engine needs to be removed to do this job.

I'm sorry to be the bearer of bad news for you on this occasion.
