Hi. New here and really don't know to much about trucks. I have a 1998 Dodge Dakota with 41,000 on it. Automatic, 2 wheel drive. Check engine light came on. Got 2 codes. 1st-P0340 Camshaft position sensor A-Bank 1 circuit malfunction. 2nd-Exhaust gas temp. sensor circuit low (bank 1 sensor 1). Is this something a dealer has to fix? If so any idea on the cost? I have no idea what these are. I do know the exhaust is a little loud as I have some bad manifold bolts I guess they said. Is it bad to run with the bad bolts? Can it be causing this problem? Any help is appreciated.

sounds like ya have two bad sensors to me, however i don't have experience in this area, normally a voltage to low is either the sensor or the wiring...

 

the exhaust gas temp low code could be caused by a lose or missing o2 sensor i know my tuck threw one of those and all i did was put the sensor back in and erase the codes and it has not come back on

 

Started the car today and check engine went out. This has happened before when it has 3/4 tank of gas. Top it off and about 2-6 starts it goes off.

 

do you fuel with it on...if so dont, this will throw a cel also look at the o ring on the gas capcould be leaking do you hear a hiss when you take the cap off?is ur truck pre 2000? if so have the code pulled, guessin a p0456 or ah i cant rember...evap code

 

My light was on, had the o2 code. I checked around, put on a new gas cap and reset the engine light by disconnecting/reconnecting the negative terminal on the battery. Been OK for a week, I'll keep you posted if the light comes back on.
