P0369 code definition
The P0369 code is a notification that the camshaft sent an outgoing signal from position sensor “B” from bank one that was missed at some point. It is an intermittent issue that is an electrical circuit problem.
What the P0369 code means
Vehicles that can report this type of code run on a single camshaft in block. Its PCM relies on the camshaft position sensor to report when the crankshaft sensor signal is accurate, when a crankshaft position sensor signal is timed to cylinder one for timing and for fuel injector starting/synchronization.
Codes P0340 and P0341 are also associated with this one. The only real difference between these three codes is how long their respective problem lasts for and the type of electrical problem affecting the circuit/sensor/engine.
What causes the P0369 code?
There are a number of causes that could be behind your vehicle’s P0369 code. The most common reasons are:
- A dead/weak battery
- A faulty starter motor
- A starting system circuit
- Camshaft position sensor circuit poor electrical connection
- A faulty camshaft position sensor
- A camshaft position sensor harness that is shorted or open
- A camshaft position sensor circuit that has a poor electrical connection
What are the symptoms of the P0369 code?
It might not even start for you or, if it does, you may still feel a lack or loss of power when you’re trying to drive. The engine may also rattle or otherwise struggle when you try accelerating. Usually, a Check Engine Light will come on too.
How does a mechanic diagnose the P0369 code?
The mechanic will use a camshaft position sensor that will work with a metal reluctor ring on the end of the camshaft. This and other specialty tools (e.g. a digital ohmmeter, scanner, oscilloscope, etc.) will be used to program the PCM with ignition timing reference values that will help to diagnose the problem.
Most likely, they will also carry out a visual inspection of the wiring, connectors and other components involved in the camshaft.
Common mistakes when diagnosing the P0369 code
It’s important to keep in mind that the P0369 code is in reference to the camshaft position sensor circuit – every component of it. Otherwise, it’s too easy to simply blame the problem on the sensor and rush to replace it. The entire system needs to be looked at and if the sensor is bad, make sure it’s replaced with a quality OEM part so you’re not in the same position in the near future.
How serious is the P0369 code?
The P0369 code shouldn’t worry you too much, but it does mean your vehicle is going to lack for power until it gets fixed. As we mentioned above, in some cases, this could mean your vehicle is idling when you’re on the road, though, which is definitely frustrating and inconvenient.
What repairs can fix the P0369 code?
Typical avenues for fixing the problems related to P0369 are:
- Testing the battery
- Repairing/replacing any disconnected, shorted, damaged, or corroded wires, connectors, or other components
- Testing the camshaft for irregular ignition timing
- Test-driving the vehicle after any of the above repairs to see if the code returns
Additional comments for consideration regarding the P0369 code
In some vehicles, contaminated engine fluid has corrupted the camshaft sensors, which has been enough to cause the P0369 code. In other vehicles, the code will be triggered if there’s something wrong with the crankshaft sensor, despite the fact that it’s meant to represent problems with the camshaft.
