My N/A is showing the following codes on my cheap handheld OBDII scanner

 

P0378 timing reference = high resolution signal B intermittent or erratic pulses

C3F00 manfacturer control

P0312 cylinder 12 misfire !!!! no idea on that

P1900 manufacturer control

 

Would I be right in assuming there are two crankshaft position sensors? ie A and B for crankshaft position.

 

the car starts up ok runs fine will even rev no problem from throttle input. After a short time it drops on to two cylinders and into limp mode ie I cannot get it to rev at all just sits there at approx. 1000rpm.

I am hoping someone can a confirm there are two sensors therefore should be sensor B failing when getting hot re code P0378

 

Or can someone point me in the right direction for finding the z22 codes

Try another coilpack

Try another coilpack

 

i have tried another but not sure if it was working ok got it from a scrap zafira with a 2.2 z22se

[vocky]

there is only the one crank sensor, but the coilpack also provides a signal to the ECU for the ignition timing position

Not sure the reader is getting the correct codes... Eg. P0378 does not exist on the 2.2 AFAIK and P0312 would also be nonsenical on a 4 cyl.
