Code P16D3 Description
The P16D3 diagnostic trouble code (DTC) indicates a problem with the Intake Rocker Arm Solenoid Valve 2 Control Circuit High Voltage. This means that the engine control module (ECM) has detected a higher than normal voltage coming from the solenoid valve that controls the intake rocker arm. The intake rocker arm solenoid valve is responsible for controlling the flow of oil to the intake rocker arm, which in turn controls the opening and closing of the intake valves in the engine. When the control circuit voltage is too high, it can lead to improper operation of the intake rocker arm, affecting the engine's performance.
Common Causes of P16D3
- Faulty intake rocker arm solenoid valve
- Wiring or connector issues in the control circuit
- ECM software or hardware malfunction
- Low oil level or poor quality oil
- Mechanical issues with the intake rocker arm assembly
Symptoms of P16D3
- Rough idling or engine misfires
- Reduced engine performance or power
- Illuminated check engine light
- Engine stalling or hesitation
- Increased fuel consumption
How to Fix P16D3
- Diagnose the issue using a scan tool to confirm the P16D3 code
- Inspect the intake rocker arm solenoid valve, wiring, and connectors for any damage or loose connections
- Test the voltage and resistance of the solenoid valve to determine if it is functioning properly
- Replace the intake rocker arm solenoid valve if it is found to be faulty
- Clear the DTC and perform a test drive to ensure the issue has been resolved
Cost to Fix P16D3
