I have been having my check engine light show up a few times fir the past couple of days. I assumed it was just a loose gas cap cover (as when I shut down the truck and fiddled with it, that seemed to make it go away. Until yesterday after work, the light went on and I thought "man I gotta have them replace that stupid gas cap." Well, I have a short trip home and it involves a quick highway segment. When I went to get up to speed on the on ramp and hit about 3/4 throttle (I like to zoom on if there's noone in my way) the thing started hesitating (felt a lot like the engine cutting out or backfiring badly.)
Made it home fine (as long as I didn't push it hard it seemed drivable) and took it to the local service shop (there is a really good one around here that most of the people at work recommended.) They fixed it up the same day (under warranty so no cost!) I asked the guy what went wrong and he said it had 2 codes showing, P0340 and P0344, so they replaced the cam sensor. Seems to have resolved the issue. Anyone know what those 2 codes actually mean (he mentioned one of them meant that sensor was failing.)

Thanks,

If it was your gascap then you would have seen "GASCAP" displayed where your mileage is lol been there, done that!


Idk what they mean but I looked them up incase you wanna read on em...


P0340 is here:

Then I found this for P0344:

That's intake cam sensor.

P0344 = Camshaft position sensor
'A' circuit intermittant (Bank 1 or single sensor)

'A' circuit is intake side. 'B' circuit is exhaust side.



Hope that helps, I'm sure someone else can explain it more to you....

 

wow lucky.. last time i saw that code i was rebuilding my engine LOL
