Ok, I was sitting at a stop light, AC on, when the car starts to idle a little rough. The light turns green, I give it gas and nothing happens, except it dies. I started it back up (after cranking over about 15 times) and I now have a Service Engine Soon light on. I drive it home, running like ****. Scan the ODB II and get these codes

P0335 - Crankshaft Position Sensor A Circuit Malfunction
P0340 - Camshaft Position Sensor Circuit Malfunction


My car is stock, except for the RnR turbo back exhaust and eibach springs. Does anybody have an idea, something I can look at?? I want to make sure that it's not something stupid, before I take it into the dealer and they *** ream me because they will try to make it sound like my exhaust broke it.

 

Check for Vacuum leaks, I found after I installed my Boost gauge, the line for my Blowoff valve came off.. the car would barely idle and stall.. When I put it back on, it was fine..

also, since your getting a code for a crankshaft/camshaft sensor, check your wiring harness that goes to the cam angle sensor on the lower right corner of your valve cover.. make sure it didn't get knocked off or come loose.

Also, reset your ECU and see if it comes back.. easiest thing for you to do is just disconnect the battery cables and let it sit for a few hours.. It might help, at least it should clear the code and you can see if it comes back.

 

Oh another thought, check your intercooler hoses and your DV (Blowoff valve) hoses.. If anything popped off for any reason, it would run like crap, though I don't know what sort of P code it might throw (Unlikely a Cam/Crank sensor error, but its worth noting.)

 

I would definitely call mitsu and have it towed to them and have them check it out... those sensors should not be showing unless you have either a failure of the sensors or an issue with the poistion of the crank or cam shafts. this is a big deal if they are correct and showing an issue.

just my 2cents
