Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
If you remove the oil cap and have a helper crank the engine while you watch through the oil fill hole, can you see movement in the head?
Well there aren't a lot of possibilities when you are only seeing P0340, and that is the easiest one to check without any tools. If the timing belt fails, there is no upper engine movement and the computer sees crank sensor movement without cam sensor movement it automatically sets a P0340.Hopefully that isn't the case and it is just a bad cam sensor (as Duralast ones as with most aftermarket cam sensors just plain won't work in these cars), but it is a quick and easy inspection we can make in the interim.
Any word on upper engine movement?
I'm sorry about that, I don't have access to the email information for the site. You can send a message to***@******.*** to correct any mistakes we might have in that department.
Ugh, thats a bummer. At least you know now and can get on to replacing the belt and checking for valve damage.
