Code P055D Buick Description
The P055D Buick code indicates a problem with the intake camshaft position actuator oil pressure sensor circuit, specifically detecting a high voltage. This sensor is responsible for monitoring the oil pressure in the system that controls the intake camshaft position actuator. When the voltage is too high, it can lead to improper functioning of the actuator, affecting the timing of the intake camshaft and potentially causing drivability issues.
Common Causes of P055D Buick
- Faulty intake camshaft position actuator
- Wiring issues or poor connections in the sensor circuit
- Low oil pressure in the system
- Engine oil contamination
- Electronic control module (ECM) malfunction
Symptoms of P055D Buick
- Engine misfires or rough idling
- Decreased fuel efficiency
- Engine stalling or hesitation during acceleration
- Illumination of the Check Engine Light
- Reduced overall engine performance
How to Fix P055D Buick
- Begin by performing a thorough inspection of the intake camshaft position actuator, oil pressure sensor, and related wiring for any visible damage or signs of wear.
- Test the oil pressure in the system to ensure it is within the manufacturer's specifications.
- Replace the intake camshaft position actuator and/or oil pressure sensor if they are found to be faulty.
- Repair any damaged wiring or connections in the sensor circuit.
- Clear the diagnostic trouble codes and test drive the vehicle to confirm that the issue has been resolved.
Cost to Fix P055D Buick
The typical repair costs for addressing the P055D Buick code can range from $200 to $500, depending on the specific components that need to be replaced and the labor involved.

Frequently Asked Questions about P055D Buick Code
1. What does the OBDII code P055D mean on a Buick?
P055D indicates a high voltage issue in the Intake Camshaft Position Actuator Oil Pressure Sensor Circuit. This sensor monitors oil pressure for the intake camshaft actuator.
2. What are the common symptoms of code P055D on a Buick?
Symptoms may include rough idling, reduced engine performance, delayed acceleration, poor fuel efficiency, and the illumination of the check engine light.
3. What causes the P055D code to appear on a Buick?
Common causes include a faulty oil pressure sensor, damaged wiring or connectors, low engine oil levels, or a malfunctioning intake camshaft actuator.
4. Can low engine oil cause the P055D code on a Buick?
Yes, insufficient oil levels or dirty oil can lead to improper camshaft actuator operation and trigger the P055D code.
5. How do I diagnose the P055D code on my Buick?
Use a diagnostic scan tool to confirm the code, inspect the oil pressure sensor wiring and connectors for damage, and check the engine oil level and condition.
6. Can I drive my Buick with the P055D code?
Driving with this code is not recommended, as it can lead to poor engine performance and potentially cause further damage to the engine if left unresolved.
7. How do I fix the P055D code on a Buick?
Repairs may include replacing the oil pressure sensor, repairing damaged wiring, cleaning or replacing the camshaft actuator, or performing an oil change if the oil is dirty or low.
8. How much does it cost to fix the P055D code on a Buick?
Repair costs vary but typically range from $100 to $300, depending on whether the oil pressure sensor, wiring, or camshaft actuator needs replacement.
9. Can an electrical issue cause the P055D code?
Yes, damaged or corroded wiring, loose connectors, or a short circuit in the sensor circuit can cause the high voltage reading that triggers this code.
10. Will clearing the P055D code fix the issue permanently on my Buick?
Clearing the code without addressing the root cause will not fix the problem, and the code is likely to return. Proper diagnosis and repair are necessary.
