This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's computer not getting enough power to control a part that helps the engine run smoothly.
The engine control module (ECM) is not receiving the correct voltage for the sensor supply, affecting the camshaft position actuator on bank 2.
The P1573 code indicates that the ECM has detected a low voltage condition in the sensor supply circuit B, which is responsible for providing power to the camshaft position actuator on bank 2. This can affect the timing of the engine and result in poor performance.
• Check Engine Light is on
• Engine runs rough
• Poor fuel economy
• Faulty camshaft position actuator
• Wiring issues such as a short or open circuit
• Defective ECM
ECM: Engine Control Module
Camshaft: A shaft in the engine that controls the opening and closing of valves
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the camshaft position actuator for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty camshaft position actuator.
• Replace or reprogram the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• BMW M5 (E39)
• BMW M3 (E46)
• BMW X5 (E53)
• Regular maintenance checks
• Ensure proper electrical connections
• Use quality replacement parts
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional.
• Avoid driving the vehicle if it runs poorly.
Check with the vehicle manufacturer for powertrain warranty coverage.
This code is often associated with BMW vehicles using the S54 or S62 engines, known for camshaft position actuator issues.
Moderate – It should be addressed soon to prevent further engine performance issues.
Driving with a malfunctioning engine control system can lead to safety hazards and may not comply with emissions regulations.
• Engine running
• Vehicle in diagnostic mode
The camshaft position actuator is located on the engine, near the camshaft.
Q: Can I drive with a P1573 code?
A: It's not recommended as it can cause further engine issues and poor performance.
Q: How do I reset the Check Engine Light after repair?
A: Use an OBD-II scanner to clear the code after ensuring the issue is fixed.
