Lexus Code P1363 – Open/Low/High Camshaft Position Actuator “B” Circuit, Bank 2

P1363 Code Description Lexus

The P1363 code for a Lexus indicates a problem with the open, low, or high circuit of the camshaft position actuator “B” on bank 2. This means there is an issue with the electrical circuit that controls the camshaft position actuator on the engine’s second bank. The camshaft position actuator is responsible for adjusting the camshaft timing, which is crucial for engine performance and efficiency. When this circuit does not function properly, it can lead to poor engine performance, reduced fuel efficiency, and even engine misfires.

Common Causes of P1363 Code Lexus

NOTE: The listed causes may not be a complete list of all potential issues, and there could be other causes.

1. Faulty camshaft position actuator: The actuator itself may be defective, resulting in an open, low, or high circuit.
2. Wiring issues: Damage to the wiring harness or connections to the camshaft position actuator can cause electrical problems.
3. Poor electrical connection: Corrosion or a poor connection at the electrical terminals can disrupt the signal to the camshaft position actuator.
4. Engine Control Module (ECM) failure: A faulty ECM can also trigger this code if it does not send the correct signals to the camshaft position actuator.

Symptoms of P1363 Code Lexus

1. Rough idling or stalling: The engine may idle unevenly or even stall due to improper camshaft timing.
2. Decreased fuel efficiency: A faulty camshaft position actuator can lead to poor fuel consumption.
3. Engine misfires: Incorrect camshaft timing can cause engine misfires, resulting in a lack of power and rough operation.
4. Check Engine Light illuminated: The P1363 code will trigger the Check Engine Light on the dashboard.
