Two years ago I installed a Holley aluminum timing cover. It doesn't leak a drop.
But.....apparently the cover was slightly out of spec and I got the P1345 code. Ultimately shimmed out the crank sensor with shims from EFI Connection and that stopped the code.
In the past year the truck has three times threw the P1345 code, cleared the codes and it doesn't come back for 2k-4k miles. Threw the code this afternoon, cleared it, drove another 10 miles and it hasn't come back on.
My question is, how can I test the ICM and crank sensors to figure if one or the other is bad (or good)?
