My CEL came on sometime in August, around a month after I get my Transmission replaced (under warranty, I'm lucky). Pulled the code, P0340. Had the CPS replaced. Cleared the code. Light came on again. Same code. What do I do now? - remy2584
ok, you need a shop to check this system, a good shop that can use a scanner and be able to find the malfunction. from here, it is tough to determine the failure without seeing it in person.
wish I could be more help, but it is difficult to diag from a distance.
