Car won't start! check engine light! Help plz

[isramirez21]

Hello everyone! :-)
Here is my problem. A few days ago my car wouldn't start, it would turn but no started.... I tried a few times and finally did started; however it showed me a check engine light, after that I just unplugged the battery for a few seconds then plugged it back in; as result the check engine light was gone. I was happy for a few days, but now it doesn't start only after a few tries( it just turns). The check engine light is back again.

So today I'll have it scanned on Autozone to see what codes shows.
I was wondering if you guys knew about this problem and could help me to diagnostic it?

I read that it Could be a camshaft sensor!?
I already checked the spark plugs, battery and they seem ok.
Should I check anything else?

It's an A4 2.8 1996

codes:

P1340 definition ckp/cmp sensor signals out of sequence

explanation
timing belt jumped

probable causes

1-Failed cmp or ckp sensor
2-Poor electrical connection



P1392 definition Cmp sensor bank 2 open circuit/short to positive

explanation
open or short circuit codition

probable cause

1- Failed CMP sensor



Thanks for the help

You really need to scan with a Vag-Com those generica Autozone scanners really dont say whats going on. find someone in your area with vag-com

v-checker from ECS. Best thing I ever bought for my audi. Really does not do all to much but great for checking codes when your on the go and can do simple tasks such as throttle body alignment.

Without codes is like finding a needle in a hay stack at night lol, get the codes first. then will go from there

BUMP!

It's just the camshaft sensor! I have just cleaned the connectors and the car starts and runs great. I havent changed the sensor yet since the cleaning did the trick.:-)
I probably change it in the future.;-) but for now it works ok.:-) I have only cleaned one, I know that there are two, but I couldn't find the other one on the passager's side. anybody knows where It could be? I looked everywhere but I didnt see it.:-(
