Hi. Can anyone help? I have a 64 reg Corsa D 1.0 12v. Had the timing chain replaced and afterwards the check engine light came on - code P0016 crank cam correlation. Took car back and he checked everything and car running great. However, it came on again. Took back again and mechanic replaced the sensors. Got it back and still light comes on. If I clear the code, it comes back on again every second start. Car is running fine. I don't trust the garage that did the replacement as the guy just keeps fobbing me off. Help appreciated.
