Could a bad cps cause a misfire
A bad Crankshaft Position Sensor (CKP
) can cause a misfire issue. We've seen it on this forum many times when swapping in a non OEM sensor as they are notorious for this exact problem.
A bad Camshaft Position Sensor (CPS
) can also cause misfire issues as well. In a distributor-less engine a bad CPS will allow the cylinders to go out of time.
In your case I would start with replacing the non OEM CKP with an OEM version. If your dealer is worth it's weight in salt and has been made aware that the CKP was recently replaced they will check this first.
