Camshaft Sensor

[ABrown]

Hi - I drive an 03 PT Cruiser and just had new spark plugs and spark plug wires installed a week ago due to jerking/hesitating when accelerating on the highway. That fixed the problem and the car seems to be running fine except my check engine light popped on yesterday. The error code is P0340 which is the camshaft sensor from what I understand. My question is could having the plugs/wires replaced have caused something to go wrong with the camshaft or is it just coincidence?

Welcome to the forum.

It should be just a coincidence, unless they somehow managed to jerk/pull the wires of the sensor. The sensor is on the side of the motor whereas they should have only dealt with pulling the upper manifold and loosening a few bolts on top to get at the plugs and wires.

Here's picture of the camshaft sensor. Look for it on the right side of the engine near the top as you stand in front of the car. Check the wires and connection as much as your can.

Need to take air intake off to get at it. People have paid $45-$70 for the part, my son-in-law had it replaced for under $100 at a service chain.
