P0340 Camshaft Position Sensor Circuit Malfunction (Bank 1)

Technical Description

The vehicle is experiencing a malfunction in the camshaft position sensor circuit.

What does that mean?

This diagnostic trouble code (DTC) is a generic powertrain code that applies to all makes and models of vehicles (1996-newer). However, the specific repair steps may vary slightly depending on the model. Therefore, this engine code article is applicable to Nissan, Ford, Toyota, Chevrolet, Dodge, Honda, GMC, etc.

The P0340 code indicates that a problem has been detected in the circuit of the camshaft position sensor.

Since the issue is related to the circuit, it could be located in any part of the circuit, including the sensor itself, the wiring, or the PCM. Simply replacing the CPS (camshaft position sensor) may not necessarily resolve the problem.

  • Replace the camshaft position sensor if necessary
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as necessary
  • Diagnose and replace the PCM if necessary
