Has anyone had any issues with their CKP sensor. It's the little "hall effect" sensor located just rear of the crank pulley. I don't have an aftermarket pulley (i.e. Perrin, Agency, etc), and I've not been in that area of the engine for any reason (no need to).

My dealer replaced the CKP sensor a few months back, but this morning, my little xA seemed to hesitate a bit when starting and sure enough the CEL popped on within a couple of seconds.

If anyone's been having this or a similar problem, I'd like to hear about it. One member on EchoFans suggested that my crankshaft position wheel may have a crack in it. Structurally, it may not be critical. However it is a 32 tooth wheel with one tooth purposefully missing for timing purposes and having a small crack in it may confuse the sensor as to where the actual missing tooth may be.

Yes, I will be taking it into the dealer as soon as I get the chance.

Thanks,

Al
