About 3 months ago my 2003 lancer es blew a clutch, i let the car sit for about a month and decided to bring it to the shop to get it fixed, when i tried to start it check engine light came on p0340 camshaft sensor...

i replaced the sensor and still same code, i then checked for spark and sure enuff cylinder 2 and 3 aint firing so i changed the coil and plugs, still same problem...i then bought a computer from the wreckers, installed it and still same problem!

I had enuff of it and brought it to the shop, mechanic went right threw the whole circuit grounds and all, nothing wrong with any of the wires, he decided to check the timing and belt and they were fine, i even put a new crank sensor in when he had it all ripped apart, still the same!

He said there was notin else he could do, the only other thing he could think of was the MAF sensor is done or the computer has to be re-set because i got it from the wreckers, but the numbers on the computers are the same, the closest mitsubishi dealership is an hour and a half from me...

any ideas? what do think about the maf sensor? does my new computer really have to go to the dealership to get matched up with my car?

 

I had a similar problem on my Evo and it turned out to be the map sensor. It threw the same code and ran like ****. Not sure if this applies to a lancer but thought I would throw it at ya.

 

hey guys, i fugured it out today...it was a combo of my computer and camshaft position sensor...the brand new one i bought from napa was absolute junk!!!!!!!!!!!! i learnt my lesson an will never go aftermarket with those kind of sensors ever again!!, i plugged the old camshaft sensor in with the computer i got from the wreckers and it fired up right away
hope this helped n e1 else that is havin this problem! now i just gotta deal wit the smoke from the motor for not bein started in 3 months lol
