2004 Mitsubishi Eclipse Q&A
2004 Mitsubishi Eclipse Question: Cam sensor was replaced engine light still on
P0421 indicates low 'warm-up' catalytic converter efficiency. Your check engine light would still be on for that. P0335 and P0340 indicate a camshaft position sensor corcuit problem. I don't have enough information to know about the high idle problem. could be related to having no cam sensor signal.

Drove the car which was running perfect, parked it in the garage and the next day it would not start, it will only crank. Thought it was a fuel pump problem as no fuel was being sent to the engine...
