My Crossfire recently quit running and the dealer replaced the camshaft sensor. After the replacement they got a P0140 error code and want to replace the relay sensor for more than $400. I have had the check engine and oil lights on for some time with no issues. I've been searching this site for solutions. Most say it's not an issue. I live in a small town on the coast of Washington and I doubt the local dealership knows much about Crossfires. Wondered if anyone had any advice.
Thanks.

 

I had same problem but did what most comments suggested, I took the rcb out and re-soldered the joints on the relay. Took small thin piece of sand paper and sanded contacts. so far no code.

 

A P0140 code is an oxygen sensor code, from the manual :
