P011C Code - Charge Air Temperature/Intake Air Temperature Correlation Bank 1
Quick Answer
The P011C diagnostic trouble code (DTC) refers to a discrepancy between the charge air temperature (CAT) and intake air temperature (IAT) sensors on Bank 1 of the engine. Common causes include Faulty charge air temperature sensor, Faulty intake air temperature sensor, Wiring or connection issues. 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 P011C Description
The P011C diagnostic trouble code (DTC) refers to a discrepancy between the charge air temperature (CAT) and intake air temperature (IAT) sensors on Bank 1 of the engine. In modern vehicles with turbocharged or supercharged engines, the CAT sensor measures the temperature of the compressed air entering the engine, while the IAT sensor measures the temperature of the ambient air entering the engine. The ECU (Engine Control Unit) compares the values from these sensors to ensure that the engine is receiving the correct amount of air at the right temperature for optimal combustion.
Common Causes of P011C
- Faulty charge air temperature sensor
- Faulty intake air temperature sensor
- Wiring or connection issues
- Sensor calibration problems
- Issues with the air intake system
Symptoms of P011C
- Check Engine Light illuminated on the dashboard
- Reduced engine performance or power
- Poor fuel efficiency
- Rough idle or stalling
- Increased emissions
How to Fix P011C
- Use a diagnostic scan tool to retrieve the DTC and confirm the P011C code.
- Inspect the charge air temperature sensor and intake air temperature sensor for any signs of damage or malfunction.
- Check the wiring and connections related to the sensors for any loose connections or corrosion.
- Test the sensors for proper operation and calibration, replacing them if necessary.
- Clear the DTC and perform a test drive to verify that the issue has been resolved.
Cost to Fix P011C
The typical repair costs for addressing a P011C code can vary depending on the specific cause of the issue and the vehicle make and model. In general, replacing a faulty sensor or addressing wiring issues may cost anywhere from $100 to $300, including parts and labor. However, additional diagnostic time and labor charges may apply, with total repair costs potentially ranging from $150 to $500. It's advisable to consult with a trusted mechanic or auto repair shop for a more accurate estimate based on your vehicle's specific needs. Keep in mind that labor rates can vary between different locations, shops, and types of repair facilities.
