Understanding what an OBD-II code means is the first step in fixing it. If you’ve encountered the P0349 code for the first time, you should definitely read this article to get a better understanding of this code and find out its common causes and symptoms.
What Does the P0349 Code Mean?
Diagnostic trouble code (DTC) P0349 stands for “Camshaft Position Sensor ‘A’ Circuit Intermittent Bank 2.” This generic powertrain code can show up in a variety of vehicles with OBD-II.
The camshaft position sensor monitors the rotational position of the camshaft and sends this information to the PCM to control parameters, such as the timing of fuel injection. An irregular signal from the camshaft position sensor(s) can trigger your PCM to store a P0349 code. This DTC might be the result of an intermittent electrical circuit fault.
The bank 2 portion of the code refers to the side of the engine that doesn’t have cylinder number one. Sensor “A” refers to the first sensor on that side of the engine if there is more than one sensor.
Note: The definition of code P0349 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
What are the Common Causes of the P0349 Code?
A P0349 code can be caused by a number of factors. Here are some of the most common causes of P0349 code

- Circuit problems, such as a damaged wire or poor connection
