The P0365, P0366, P0367, P0368, and P0369 codes have to do with Camshaft Position Sensor “B.” The camshaft position sensor (CMP) determines the position of the camshaft in relation to the crankshaft.
This allows both of these parts to move in tandem and gives the powertrain control module (PCM) the information necessary to run the fuel injectors, ignition system, and anything else necessary within the engine.
What Does Code P0365 Mean?
P0365 is a generic powertrain trouble code for “Camshaft Position Sensor ‘B’ Circuit Bank 1.” Many modern vehicles.
The camshaft position sensor monitors the rotational position of the camshaft and sends that data signal to the powertrain control module (PCM) to operate the fuel injectors and, in some cases, the ignition coils and variable valve timing system.
A P0365 code may be set if the PCM detects an irregular signal from the camshaft position sensor. You shouldn’t assume that a stored P0365 code can be fixed by replacing the camshaft position sensor itself. There might be other problems involving (but not limited to) the sensor, wiring, or the PCM.
It is advised that you change both the sensors once you see the P0365.
If the error code mentions that its a Sensor A circuit> it means the Intake Sensor has gone bad.
If the error code mentions that it is a Sensor B circuit> it means the Exhaust Sensor that has gone bad.
The intake sensor & the exhaust sensor look similar in appearance except that the Intake sensor has the bolt hole at an angle (vs) the exhaust sensor which has the bolting hole in line with the sensor. Please check images enclosed of the sensors.
Once both the sensors are changed and error codes cleared, you should be good for the rest of the lifetime of the vehicle.
Potential Causes of a P0365 Code
There are many potential causes for the P0365 code, including the following:
- A faulty camshaft position sensor
- Oil leaking onto the sensor and damaging wiring or corroding connections
- Short or open in the sensor circuit
- Faulty PCM (rare)
- Crankshaft position sensor failure
P0365 Code Symptoms
It is possible to experience several different symptoms with the P0365 code, including:
- Check Engine Light on
- Loss of power during operation
- Lack of power
- Engine misfiring (running rough)
- Hard starting
- No start
- Engine stalling
How to Fix P0365
During Diagnosing of errors of p0431 code below step will be following.
- Diagnosing the P0365 code is to connect an OBD-II scanner to the car’s computer and check all the codes stored. The mechanic will then need to clear the codes and test drive the vehicle to see if the code is reset.
- Next, the mechanic should inspect the wiring and connections to the camshaft position sensor. Any damaged wiring should be repaired or replaced, and loose or corroded connections will need to be repaired as well. It may be necessary to pull the sensor from the engine and test it for resistance.
- If an oil leak is responsible for damaging the sensor, the wiring or the connectors, the oil leak will need to be repaired to prevent the same situation from recurring. Note that if the crankshaft sensor has also failed. it should be replaced with the camshaft sensor.
- The mechanic should also inspect and diagnose the PCM. While rare, a faulty PCM can also cause the P0365 code, and may need to be replaced in some instances.
How Much Does It Cost to Fix a P0365 Code?
To fix a P0365 code, which indicates a faulty camshaft position sensor “B” circuit, you can expect to pay between $100 and $300 depending on your vehicle, including the cost of the replacement sensor and labor to install it; with most cases falling within the $150 – $200 range.
