P1114 Code - Intake Air Temperature Sensor 2 Circuit Low

Quick Answer

The P1114 diagnostic trouble code (DTC) refers to the Intake Air Temperature Sensor 2 Circuit Low. Common causes include Faulty Intake Air Temperature Sensor: The sensor itself may be malfunctioning, providing incorrect readings to the engine control module, Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can cause a low voltage signal, Poor Electrical Connection: Loose or poor electrical connections at the sensor or ECM can lead to a low signal. 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 P1114 Description

The P1114 diagnostic trouble code (DTC) refers to the Intake Air Temperature Sensor 2 Circuit Low. This code indicates that the signal from the intake air temperature sensor 2 is lower than the expected range. The intake air temperature sensor measures the temperature of the air entering the engine, which is crucial for the proper air-fuel mixture and engine performance. When the sensor detects a low voltage or resistance, it can lead to incorrect fuel delivery and ignition timing, resulting in poor engine performance, decreased fuel efficiency, and increased emissions.

Common Causes of P1114

  1. Faulty Intake Air Temperature Sensor: The sensor itself may be malfunctioning, providing incorrect readings to the engine control module.
  2. Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can cause a low voltage signal.
  3. Poor Electrical Connection: Loose or poor electrical connections at the sensor or ECM can lead to a low signal.
  4. Engine Coolant Temperature Sensor Failure: A malfunctioning engine coolant temperature sensor can affect the intake air temperature sensor readings.
  5. PCM/ECM Issues: Problems with the powertrain control module or engine control module can also trigger this code.

Symptoms of P1114

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the dashboard.
  2. Poor Engine Performance: The engine may exhibit hesitation, stalling, or rough idling due to incorrect fuel delivery.
  3. Decreased Fuel Efficiency: A malfunctioning intake air temperature sensor can cause the engine to run rich, leading to decreased fuel efficiency.
  4. Increased Emissions: Incorrect air-fuel mixture can result in higher emissions output from the vehicle.

How to Fix P1114

  1. Diagnostic Scan: Use a diagnostic scan tool to retrieve the trouble codes and data related to the intake air temperature sensor.
  2. Inspect Sensor and Wiring: Check the intake air temperature sensor and its wiring for any visible damage or corrosion.
  3. Test Sensor Resistance: Verify the resistance of the sensor using a multimeter to determine if it falls within the specified range.
  4. Replace Sensor: If the sensor is faulty, replace it with a new one following the manufacturer's guidelines.
  5. Clear Codes: After replacing the sensor, clear the trouble codes and reset the ECM to see if the issue has been resolved.

Cost to Fix P1114

The cost of repairing the Intake Air Temperature Sensor 2 Circuit Low issue can vary depending on the vehicle make and model, the location of the repair shop, and the cost of the sensor itself. Typically, the parts cost for a new intake air temperature sensor ranges from $20 to $100, while labor costs can range from $80 to $150 per hour. Overall, the total repair cost for this issue could range from $100 to $300. It's advisable to get quotes from local auto repair shops to get a more accurate estimate.
