Odd OBD reading

mssri150

Car is running like shit so changed a bad looking plug still the same so I borrowed a coil pack off one that runs sweet the same then the EML came on but it's telling me it's the camshaft sensor??? They don't have one so is it the crankshaft sensor?
Going to see if my dad will plug his snap on ethos on it later but need to find a part what do you guys think?

The camshaft sensor code usually comes up when you use an aftermarket coil pack.

You need to use a genuine coil pack as it's something inside it that reads crankshaft position

Used a working original coil pack the vaux guy I know doesn't think it's crank sensor bit wants 30 to diagnose it he's just put on a new ecu

What error code is the OBD reader giving you currently?

As mentioned by @[deleted] above, usually the error means the coil pack has failed or an aftermarket unit has been used which don't have the correct sensor. There is no camshaft sensor on the Z22SE.

Replace with a genuine GM coil pack only which has the proper CSI (Compression Sense Ignition) sensor developed by Delphi.

Genuine GM part #:
Ignition Control Unit Module - 12567686 (or 12580537)
