P2090 GMC Code - Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Bank 1
Quick Answer
The P2090 GMC diagnostic trouble code indicates a problem with the Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit on Bank 1. Common causes include Faulty Camshaft Position Actuator Solenoid Valve: A malfunctioning or failed camshaft position actuator solenoid valve can cause the voltage in the circuit to drop below the specified threshold, Wiring Issues: Damaged or corroded wiring in the circuit can interrupt the flow of voltage, leading to low voltage readings, Electrical Problems: Issues with the electrical system, such as a blown fuse or a faulty ECM, can disrupt the voltage to the solenoid valve. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2090 GMC Description
The P2090 GMC diagnostic trouble code indicates a problem with the Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit on Bank 1. This means that the voltage in the circuit is lower than the specified threshold, which can lead to issues with the actuator's performance. The Exhaust Camshaft Position Actuator Solenoid Valve is responsible for controlling the camshaft position in relation to the engine's intake and exhaust valves. When the voltage in the circuit is too low, it can affect the actuator's ability to adjust the camshaft position accurately, leading to performance issues and potentially causing damage to the engine.
Common Causes of P2090 GMC
- Faulty Camshaft Position Actuator Solenoid Valve: A malfunctioning or failed camshaft position actuator solenoid valve can cause the voltage in the circuit to drop below the specified threshold.
- Wiring Issues: Damaged or corroded wiring in the circuit can interrupt the flow of voltage, leading to low voltage readings.
- Electrical Problems: Issues with the electrical system, such as a blown fuse or a faulty ECM, can disrupt the voltage to the solenoid valve.
- Poor Connections: Loose or poor connections in the circuit can lead to voltage drops and trigger the P2090 code.
- Mechanical Failure: Internal mechanical issues within the camshaft position actuator solenoid valve can cause it to malfunction and result in low voltage readings.
Symptoms of P2090 GMC
- Check Engine Light: The most common symptom associated with the P2090 code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: The engine may experience rough idling, with noticeable vibrations or shaking when the vehicle is stationary.
- Poor Acceleration: The vehicle may have difficulty accelerating smoothly or quickly, resulting in sluggish performance.
- Decreased Fuel Efficiency: A decrease in fuel efficiency may be observed, with the vehicle consuming more fuel than usual.
- Engine Misfires: The engine may misfire, leading to a lack of power and potential exhaust emissions issues.
How to Fix P2090 GMC
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and perform a thorough inspection of the camshaft position actuator solenoid valve and its circuit.
- Check Wiring: Inspect the wiring harness for any signs of damage, corrosion, or poor connections. Repair or replace any faulty wiring as needed.
- Test Solenoid Valve: Test the camshaft position actuator solenoid valve for proper functionality and replace it if it is found to be faulty.
- Reset the ECM: Clear the trouble code using a diagnostic scanner and reset the Engine Control Module (ECM) to see if the issue persists.
- Recheck and Test Drive: After completing the repairs, recheck the system for any remaining issues and test drive the vehicle to ensure that the problem has been resolved.
Cost to Fix P2090 GMC
The typical repair costs for addressing the P2090 GMC code can vary depending on the specific cause of the issue and the labor rates of the auto repair shop. Generally, the cost of replacing a faulty camshaft position actuator solenoid valve can range from $150 to $300, including parts and labor. However, additional costs may be incurred if there are wiring or electrical issues that need to be addressed. It is recommended to consult with a professional mechanic to get a more accurate estimate based on the specific circumstances of the vehicle. Keep in mind that labor rates at auto repair shops can vary between $80 and $150 per hour, so it's advisable to inquire about the rates in your local area for a more precise cost estimate.
