P0335 and P340 faults

bowlofturtle · Oct 26, 2009, 02:21 AM

As if problems weren't enought with this car. My gf calls me the other day and tells me the car wouldn't start. She tells me its actingly like what did before, which was having a hard start turning over due to weak battery. It cranked tho.

I put in a new battery about 5 months ago.

About 10 minutes later she calls again and tells me car is started but is running rough and drove it over, she said it was running rough for a breif moment and it was all good now but CEL was on. She took another drive and it started up fine and drove great.

CEL came back as P0335 and P0340. Cam and crank ciruit A issues.

This brings great fear to me, i did the Timing belt and water pump about 980miles ago, which was roughly 1 month ago. I have a feeling it might be related.

Right now car is running fine, the CEL is not on. I didn't clear the fault so i guess its not a hard fault. Maybe the light was only on due to lower battery voltage.

Do you think the timing jumped? Would one sensor's failure cause the other on to break?

I really hate this car. It never lets me sleep and rest.

i search this up a bit. i found a thread where it was started these faults occured due to a bad battery. I guess the hard starting could of a caused a low enough voltage for similiar conditions. Any thoughts on this?

Crank Position Sensor... $90ish dollar part.

Pull out a spark plug and give it a crank.. if you have no spark thats 100% it.

Cheers!

car starts and currently driving great. Other then that one time where it didn't start and then once it started it was really rough, car has been decent.

I dont want to spend $90 on something that might not be the problem.

Anything else on this? I've got an 03 I'm working on that showed a P0121, P0335, P0340, and P1400. Other than the idle dropping to 500RPM occasionally, the car drives fine and makes decent power for the mods installed. I just cleaned out the throttle body and it seemed to have better throttle response but I'm still getting a P0121, P0335, and P0340.

nope, sorry.

I dont have a hard fault. I haven't cleared it but the CEL isn't on. last time i check the faults was still stored, i didn't clear it tho.

The car is not having a problem starting at all.

I would suggest you look at the cam sensor to replace it. As i've read it is the reason for my 2 faults and reason of causing hard starts.
