Engine diagnostic trouble codes (DTC) are assigned to identify various problems in a car. There are hundreds of codes with different character combinations, meaning one cannot simply memorize all of them. For you to solve or look for the right solution, you must know what the code you’re getting on your scan tool means.
Having trouble finding out what a P0341 means and how to clear it? Read on to find out more about this OBD-II code.
What Does the P0341 Code Mean?
Diagnostic trouble code P0341 stands for “Camshaft Position Sensor “A” Circuit Range/Performance (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects a problem with the signal being sent by the camshaft position sensor.
The PCM uses the signal from the CMP sensor to determine the position of the camshaft in relation to the crankshaft. The module then uses that information to help calculate fuel injector operation and (on some vehicles) ignition timing.
To generate its signal, the sensor reads a reluctor wheel that’s typically attached to the camshaft. The signal handed out by the CMP should always coincide with the signal coming from the crankshaft position sensor (CKP).
P0341 code refers to a problem with the CMP signal on Bank 1. It could be that the signal coming from the CMP is not matching, not within the expected range, or not timed properly with the CKP’s signal. You also have to take note that this code can be set by extended cranking periods.
Meanwhile, the “A” in the code refers to the intake camshaft in a straight overhead camshaft engine. Alternatively, if the engine employs a V configuration, the “A” typically refers to Bank 1’s intake camshaft.
Finally, the “bank 1” in the P0341 code refers to the side of the engine where the number one cylinder is located. Note that this only applies to engines with a boxer or V configuration.
What are the Possible Causes of the P0341 Code?
The code P0341 can be interpreted in different ways depending on the vehicle. Here are the most common causes of code P0341:
- Faulty CMP
- Circuit problems (e.g., damaged wiring and loose connections)
- Defective or misaligned camshaft reluctor wheel
- Problems with the PCM (e.g., outdated software)
- Issues with timing components (e.g., a stretched timing chain or failed timing chain tensioner)
What are the Common Symptoms of the P0341 Code?
If you start getting a P0341 code on your OBD-II scan tool, chances are you may experience one or more of these symptoms:
- Possible engine power loss
- Engine stalls when idling
- Engine idling too low or too high
- Engine misfires and runs rough
- Increased fuel consumption
- Engine does not start
