P0344 Code: Camshaft Position Sensor “A” Circuit Intermittent (Bank 1 or Single Sensor)

The Camshaft Position Sensor is one of many sensors. It relays valuable information that the vehicle’s primary computer or powertrain control module (PCM) uses to calculate fuel injection and ignition timing. When the PCM detects that the signal from this sensor is intermittent or missing, the P0344 code gets set.

Here is a quick overview of what you need to know if you’ve retrieved this trouble code from your vehicle.

What Does the P0344 Code Mean?

Diagnostic trouble code (DTC) P0344 stands for “Camshaft Position Sensor “A” Circuit Intermittent (Bank 1 or Single Sensor).” It triggers when the PCM detects a loss of signal from the Bank 1 camshaft position sensor. Bank 1 refers to the bank of the engine that contains cylinder #1.

Other trouble codes, such as P0340 (Camshaft Position Sensor “A” Circuit) and P0341 (Camshaft Position Sensor “A” Circuit Range/Performance), may get logged at the same time as the code P0344. These codes differ in terms of how long the problem persists and the type of problem that the sensor, circuit, or engine controller experiences.

If you’re planning a DIY approach to fixing P0344, an in-depth understanding of the camshaft position sensor could help you arrive at a proper solution. You can read our advanced technical discussion about camshaft position sensors and typical locations. Otherwise, you can continue reading for the most likely causes of P0344.

Note: The definition of code P0344 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
