P0347 code definition

The P0347 Trouble Code refers to an issue with the camshaft position sensor A where the circuit input in bank 2 is too low.

What the P0347 code means

This is a generic code regarding the camshaft position sensor. Trouble codes P0335 through P0349 all refer to the CPS and each indicates a different reason for failure. In this case, the P0347 code means that the sensor’s signals are too low and it is hard to interpret. In this case, it is in the bank 2 side of the engine.

What causes the P0347 code?

Many different things can cause the P0347 code to appear including the following:

What are the symptoms of the P0347 code?

In many cases, the Check Engine Light will come on in the vehicle. In addition, the P0347 code will be stored in the vehicle. The vehicle might also suffer from a lack of power, which you will notice as you are driving around normally. The vehicle might stall, and you may also notice that it is more difficult to start.

How does a mechanic diagnose the P0347 code?

To diagnose the P0347 code, the mechanic will need to use his or her OBD-II scanner. They will connect the scanner to the vehicle’s onboard computer and then gather data regarding this vehicle. The information they get can be very helpful when they are trying to diagnose the vehicle and determine exactly what is wrong with it. The mechanic will also reset the code and take the vehicle out to drive it. They need to see if the code returns during normal operating conditions. If it does, they know that there is an actual issue with the vehicle.

Common mistakes when diagnosing the P0347 code

A common mistake when it comes to diagnosing the P0347 code is immediately blaming the sensor and replacing it. Instead, the mechanic needs to examine the entire system since the code is related to the whole of the camshaft position sensor circuit. By conducting a proper diagnosis, it ensures that they find the actual cause for the code.

How serious is the P0347 code?

The code can be a pain to deal with as a driver. In many instances, the vehicle will not have the power you need, and there is a chance that you could stall the vehicle while idling at a stop light. In addition, it can be more difficult to start. Even when the drivability issues seem minor, it is not something you will want to ignore. Make sure that you bring the vehicle to a mechanic who can diagnose it and repair it properly so the condition does not worsen.

What repairs can fix the P0347 code?

Here are some of the repairs the mechanics might use when repairing the P0347 code.

  • Check the battery’s
  • Check the wiring that runs to the starter and make repairs to it as needed, since corrosion and loose connections are common
  • Replace the starter
  • Check the connector that’s on the camshaft sensor
  • Replace the CPS, or camshaft position sensor

Additional comments for consideration regarding the P0347 code

As vehicles get older, some of the sensor modules have issues, and they present false codes when there is nothing wrong with the vehicle. While this is possible when you have a code such as the P0347 code appear on your vehicle, you do not want to take that chance. Instead, you will want to make sure you bring the vehicle to a mechanic who can take care of the codes and any needed repairs. It is always best to make sure your vehicle has the proper care so you can have peace of mind while driving.
