Fail code p001985
Hey from DK
I have a big problem. I have upgraded my timing chain on my M157 and now i have this fail code P01985 the position of the exhaust camshaft (cylinder bank 2) is implausible relative to the position to the crankshaft, there is a signal above the permissible limit.
The engine is on the timing marks, i have tried to exchange 2 sensors to see if i can move the problem, but no its the same faliure.
Can any body help me whit a good advise.
Hope to here from you
