help with check engine light?
My 2013 dart sxt has a check engine light on as well as the traction control light. the traction control light only goes on after i start driving it. it doesnt turn on every time i drive but when it does happen, the car slows down as if i had downshifted and will not go past 35 mph. i scanned for codes and it brought up P0344. So i went to a napa store near me and they sold me 2 camshaft position sensors, part number CSS1248. ive attached pictures of the code on the scanner and of the sensor that was sold to me. I replaced the easily accessible one on march 10th and everything was good up until today. the lights came back on and same symptoms. I havent put a scanner through it yet but im expecting the same codes.any advice on how to take change out the sensor thats farthest away from you as youre standing in the front?? also, could it be anything else other than the sensor?
If you have P0344 that code is specific for Bank 1 Sensor 1 of a 2.0 engine. If you have a 2.4 engine, there is only one cam sensor.
From the FSM:
There are two Camshaft Position Sensors on the 2.0L (ECK) engine. The (1/1) Exhaust Camshaft Position Sensor (2) is mounted to the front face of the cylinder head on the same side as the exhaust camshaft. The (1/2) Intake Camshaft Position Sensor (1) is mounted to the rear face of the cylinder head on the same side as the intake camshaft. Both sensors are located nearest the number four cylinder end of the engine. Both sensor connectors have three wires.
You do not need to touch the cam sensor on the intake (rear) side of the head. There would be different code for that sensor. Take that extra sensor back to the store or keep it for a spare. When an intermittent fault occurs, the problem is the usually the wiring or the connector. Removing and replacing the sensor made the problem appear to correct itself because you moved the wiring around. You will need to look for continuity or shorts to ground in the wiring to that sensor. Here is the schematic:
It is possible for an aftermarket sensor to be bad from the box. I usually get oem sensors that are critical like the CMP sensor. What the FSM lists for a P0344:
P0344-CAMSHAFT POSITION SENSOR INTERMITTENT - BANK 1 SENSOR 1
There is a caution in the install instructions:
Install camshaft position (CMP) sensor utilizing twisting motion. The sensor o-ring should be lubricated with clean engine oil. Make sure CMP sensor is fully seated. Do not drive CMP sensor into the bore with the mounting bolt. This may cause CMP sensor to be incorrectly seated causing a faulty signal or no signal at all. The mounting bolt should be tightened to 9 N·m (79.5 in. lbs.).
