What is GM code P0340?

What is GM code P0340?

The OBD-II diagnostic trouble code P0340 indicates a “Camshaft Position Sensor “A” Circuit Malfunction.” It covers the entire circuit attached to the aforementioned sensor, such as the electric wiring and the powertrain control module (PCM). The P0340 code is a generic powertrain code.

When is the p0340 GMC code detected?

When is the P0340 GMC code detected? 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.

What causes the p0340 CMP sensor to malfunction?

P0340 – Camshaft position (CMP) sensor A, bank 1 circuit malfunction Trouble Code Fault Location Probable Cause P0340 Camshaft position (CMP) sensor A, bank 1 Wiring, CMP sensor, ECM

Are there any DTCs associated with the p0340 sensor?

Double check these before coming back to the CMP. DTC P0340 or P0345 may be accompanied by other DTCs, such as P0300 Random Misfire, P0725 Engine Speed Sensor Circuit, or P0335 Crankshaft Position Sensor Circuit Malfunction.

What causes a p0340 to set on a Mustang GT?

Ford Trucks / Mustang GT – An alternator phase problem, such as a blown diode or open coil, may cause so much electrical interference that the CMP signal gets distorted, causing a P0340 / P0345 DTC to set, among others, in spite of there being no actual problem with the CMP sensor or wiring.

When is the P0340 GMC code detected? 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.

What does p0340 mean in an internal combustion engine?

What Does P0340 Mean? The camshaft position sensor located in the internal combustion engine monitors the position and rotational speed of the camshaft. It works hand in hand with the reluctor ring that creates a square wave voltage signal that the ECM interprets as the crankshaft position.

Double check these before coming back to the CMP. DTC P0340 or P0345 may be accompanied by other DTCs, such as P0300 Random Misfire, P0725 Engine Speed Sensor Circuit, or P0335 Crankshaft Position Sensor Circuit Malfunction.
