Good point. He should check to see if his crank trigger sensor has become loose or damaged. I wish this design was never implemented.

Would the check engine light come on if the crank angle sensor is bad?

If memory serves me, CAS is code 22, TDC sensor or crank angle sensor is code 23.

Would this be what I am looking for as far as the crank angle sensor? Also if there was no check engine light should I still be worried about the CAS? And would I still be getting any kind of spark out of any of the coil packs if it was bad or would they all be dead? Since one coil pack was giving spark.

Usually don't get any codes... If the ECU had a clue what was happening to it, it probably wouldn't be dropping coils.

You're looking for all the timing marks to be lined up, the signal wheel to be in good condition, and properly lined up to the gear. The notch and the mark in the gear must be lined up as in the below pic:

It is pretty rare for a CAS to fail. It is more likely the crank angle sensor is not adjusted properly or has come loose. Especially if you did the timing belt recently. Check it before replacing it. Here is a photo of its location. And yes, that is a the crank angle sensor in your photo.



This seems to be my real issue with this design is that codes do not always show up in diagnostics from what I have read on this forum. Makes it a real pain. I would much rather gamble, if I was sure the crank sensor was secured, on the coil pack and PTU. Always good to have a spare set anyway even if it proves to be the wrong bet. Plus, it is a much easier fix.

If there is ANY spark, its not the crank sensor. Most of the time when the crank sensor is "bad" its because the wires were carelessly routed the last time the timing cover was off, and something (usually a belt) chewed the wires. Its also easily checked with an ohm meter. Sometimes they get damaged at the mount point when not bolted on correctly.

Maybe it was just me but was that "warp" you were asking about, you know the stock timing belt cover does have a bulge in it?

Looks like you are tracking it down though.
