Code P011E Description

The P011E diagnostic trouble code (DTC) refers to the engine coolant temperature 1 / ambient air temperature correlation. This code indicates that there is a discrepancy or correlation issue between the engine coolant temperature sensor and the ambient air temperature sensor in the vehicle. The engine coolant temperature sensor is responsible for measuring the temperature of the engine coolant, while the ambient air temperature sensor measures the temperature of the air outside the vehicle.

  3. Wiring or connector issues
  4. ECM malfunction
  5. Corrosion or damage to sensor connectors

Symptoms of P011E

  1. Decreased fuel efficiency
  2. Rough idle
  3. Engine running rich or lean
  4. Check engine light illuminated
  5. Engine overheating or running hot

How to Fix P011E

  1. Begin by using a diagnostic scanner to retrieve the trouble codes and freeze frame data to confirm the presence of the P011E code.
  2. Inspect the engine coolant temperature sensor and ambient air temperature sensor for any signs of damage or corrosion. Replace any faulty sensors.
  3. Check the wiring and connectors for the sensors to ensure they are properly connected and not damaged. Repair or replace any damaged wiring.
  4. Clear the trouble codes from the ECM using the diagnostic scanner and test drive the vehicle to ensure the issue has been resolved.
  5. If the check engine light illuminates again after the repair, further diagnostic testing may be necessary to identify any underlying issues that were not initially detected.

Cost to Fix P011E

The typical repair costs for addressing the P011E code can vary depending on the specific cause of the issue. In general, replacing a faulty engine coolant temperature sensor or ambient air temperature sensor can cost between $50 to $100 for the part. Labor costs for sensor replacement can range from $50 to $150, depending on the shop's hourly rates. Overall, the total repair costs for resolving the P011E code may range from $100 to $300. It is advisable to check with local auto repair shops for more accurate estimates based on your vehicle make and model. Additionally, diagnostic time and labor rates can vary based on location and other factors.
