Code P011C Nissan Description

The P011C diagnostic trouble code (DTC) for Nissan vehicles specifically refers to the Charge Air Temperature/Intake Air Temperature Correlation Bank 1. This code indicates that there is a discrepancy between the intake air temperature sensor and the charge air temperature sensor in Bank 1 of the engine. The intake air temperature sensor measures the temperature of the air entering the engine, while the charge air temperature sensor measures the temperature of the air after it has been compressed by the turbocharger or supercharger.

  3. Wiring or connector issues in the sensor circuit
  4. ECM software or hardware issues
  5. Turbocharger or supercharger malfunction

Symptoms of P011C Nissan

  1. Check engine light illuminated
  2. Reduced engine performance
  3. Decreased fuel efficiency
  4. Engine misfires
  5. Stalling or rough idling

How to Fix P011C Nissan

  1. Diagnose the issue by using a scan tool to retrieve the DTC and inspecting the intake air temperature and charge air temperature sensors.
  2. Test the sensors for proper operation using a multimeter to check for resistance and voltage readings.
  3. Inspect the wiring and connectors for any damage or corrosion, repairing or replacing as necessary.
  4. Clear the DTC from the ECM memory and reset the system to see if the code returns.
  5. If the issue persists, replace the faulty sensor(s) or address any other underlying problems causing the correlation error.

Cost to Fix P011C Nissan

The typical repair costs for addressing the P011C code can vary depending on the specific cause of the issue. In general, replacing a faulty sensor or repairing wiring/connectors may cost between $100 to $300, including parts and labor. However, additional costs may apply if other components need to be replaced or if further diagnostics are required. It's recommended to consult with a qualified mechanic or auto repair shop to get an accurate estimate based on the specific circumstances of the vehicle. Labor rates at auto repair shops typically range from $80 to $150 per hour, but can vary based on location and other factors.

When is the Code Detected?

The Engine Control Module (ECM) detects a state that the difference between the temperature of the intake air temperature sensor 2 and it's estimated temperature calculated by ECM from intake air temperature 1 and turbocharger boost sensor.
