Camshaft Position Sensor A Circuit High Input (Bank 1)
Signals are showing a high voltage input from the camshaft position sensor.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The camshaft position sensor tells the engine computer where the camshaft is positioned. If the voltage it sends is too high, the computer thinks something is wrong with the sensor or the circuit.
What the computer is actually seeing
The engine control module (ECM) expects a voltage between 0.5 to 4.5 volts from the camshaft position sensor. If it sees a voltage above this range, it triggers the P0368 code.
What a healthy reading looks like
Camshaft position sensor output should be between 0.5 volts (low) to 4.5 volts (high) as the engine operates.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Verify the fault code by rescanning the vehicle.
- 2Inspect the camshaft position sensor connector for corrosion or damage.
- 3Check the wiring between the injector and the ECM for any shorts or open circuits; repair as needed.
- 4Measure the voltage at the camshaft position sensor while cranking the engine. It should be between 0.5 and 4.5 volts. If it's above this range, replace the sensor.
- 5If the sensor is good, check the signal return to the ECM for faults.
Common causes
- Faulty camshaft position sensor
- Short circuit in the wiring
- Open circuit in the wiring
- Faulty connector to the sensor
- Misalignment of the camshaft sensor
Typical repair cost
$$ ($100 - $300)

Frequently asked questions
Is it safe to drive with this code?
It depends on the symptoms. If the engine runs rough or stalls, it's best to fix it soon.
Will this code come back after clearing it?
If the underlying issue isn't resolved, yes, it typically will come back.
Why does this code pair with other codes?
Faults in the camshaft sensor can affect timing, which may trigger other sensor codes.
