How do you test a GM camshaft sensor?
How To Testing A Two-Wire Sensor:
- If you have a two-wire, magnetic-type sensor, set your multimeter to “AC volts.”
- Have an assistant turn the ignition key on without starting the engine.
- Check for the presence of power flowing through the circuit.
- Have your helper crank or start the engine.
Why does the p0340 GMC camshaft position sensor malfunction?
The change in the magnetic field cause the voltage from the sensor to change. When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

How to diagnose a GMC camshaft position sensor malfunction?
Start by checking the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The cost to diagnose the P0340 GMC code is 1.0 hour of labor.
What does it mean when your engine code is p0341?
A code P0341 may mean that one or more of the following has happened: Cam sensor wiring routed too close to spark plug wiring (causing interference) Poor wiring connection at cam sensor Poor wiring connection at PCM NOTE: In some cases this engine code is generated on vehicles that do not actually have a camshaft position sensor.
How long does it take to diagnose a p0340 GMC code?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The cost to diagnose the P0340 GMC code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.

What do you need to know about the p0340?
P0340 Description. The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection.
