P106A Code - Evaporative Emission System Pressure Sensor - Manifold Absolute Pressure Correlation
Quick Answer
The P106A code indicates a problem with the Evaporative Emission System Pressure Sensor - Manifold Absolute Pressure Correlation. Common causes include Faulty Pressure Sensor: The pressure sensor itself may be faulty, providing incorrect readings to the vehicle's computer, Wiring Issues: Damaged or corroded wiring connecting the pressure sensor to the vehicle's computer can lead to communication errors, Vacuum Leaks: Any leaks in the vacuum lines connected to the evaporative emissions system can disrupt pressure readings. 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 P106A Description
The P106A code indicates a problem with the Evaporative Emission System Pressure Sensor - Manifold Absolute Pressure Correlation. This system is responsible for monitoring the pressure in the fuel tank and detecting any leaks in the evaporative emissions system. The pressure sensor measures the pressure in the fuel tank while the Manifold Absolute Pressure (MAP) sensor measures the pressure in the intake manifold.
Common Causes of P106A
- Faulty Pressure Sensor: The pressure sensor itself may be faulty, providing incorrect readings to the vehicle's computer.
- Wiring Issues: Damaged or corroded wiring connecting the pressure sensor to the vehicle's computer can lead to communication errors.
- Vacuum Leaks: Any leaks in the vacuum lines connected to the evaporative emissions system can disrupt pressure readings.
- Faulty MAP Sensor: A malfunctioning Manifold Absolute Pressure sensor can also trigger this code by providing inaccurate pressure readings.
- EVAP System Leak: A leak in the evaporative emissions system can also cause the correlation between the pressure sensors to be off.
Symptoms of P106A
- Check Engine Light: The most common symptom associated with the P106A code is the illumination of the check engine light on the dashboard.
- Decreased Fuel Efficiency: A malfunctioning evaporative emission system pressure sensor can lead to decreased fuel efficiency as the engine may not be running optimally.
- Rough Idle: The engine may experience rough idling or hesitation when accelerating due to incorrect pressure readings.
- Failed Emissions Test: If the issue is not resolved, it can lead to the vehicle failing an emissions test due to increased emissions.
- Gasoline Smell: A leak in the evaporative emissions system can sometimes result in a gasoline smell coming from the vehicle.
How to Fix P106A
- Diagnostic Scan: Use an OBD-II scanner to retrieve the specific code and pinpoint the issue with the evaporative emission system pressure sensor.
- Check Wiring: Inspect the wiring harness connecting the pressure sensor to the vehicle's computer for any damage or corrosion. Repair or replace as needed.
- Replace Pressure Sensor: If the pressure sensor is faulty, replace it with a new one and ensure it is properly calibrated.
- Check and Repair Vacuum Lines: Inspect all vacuum lines connected to the evaporative emissions system for any leaks or damage. Replace or repair as necessary.
- Clear Codes: After completing the repairs, clear the diagnostic trouble codes from the vehicle's computer and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P106A
The cost of repairing the Evaporative Emission System Pressure Sensor - Manifold Absolute Pressure Correlation issue can vary depending on the specific cause of the problem and the make and model of the vehicle. In general, the cost of parts for this repair can range from $50 to $200, while labor costs can range from $100 to $300. Overall, the total cost of this repair can be anywhere from $150 to $500, including parts and labor. It's important to note that these are rough estimates and actual costs may vary based on the factors mentioned earlier. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate cost estimate.
