This code relates to an issue with the camshaft or crankshaft position sensor, and commonly affects Chevrolet and GMC vehicles, but is not limited to just those manufacturers.

The camshaft position sensor gathers information about the vehicle's camshaft speed and sends it to the vehicle's engine control module (ECM).

A camshaft position sensor code for that year and model should be P0340 when scanned with a proper scan tool. Assuming that you do indeed have a P0340, replacing the sensor would be a good start.

Some vehicles also have a camshaft position sensor that allows the engine computer to monitor the position of the camshafts (or camshaft), which open and close the valves, for more precise fuel ...

The Problem: The crankshaft position sensor tone wheel may delaminate, causing the engine to lose its ability to synchronize the fuel injector pulses and camshaft timing, possibly resulting in an ...

This paper describes a dual-track magnetic crankshaft and camshaft position sensor configuration. It uses semiconductor sensors such as magnetoresistors to pick up the magnetic flux modulation created ...
