P00E2 Code - Charge Air Cooler Coolant Temperature Sensor 'A' Intermittent/Erratic

Quick Answer

The P00E2 diagnostic trouble code (DTC) refers to the Charge Air Cooler Coolant Temperature Sensor 'A' Intermittent/Erratic. Common causes include Faulty Sensor: The most common cause of this code is a malfunctioning charge air cooler coolant temperature sensor, Wiring Issues: Corrosion, damage, or loose connections in the sensor's wiring can also trigger this code, ECM Malfunction: A fault in the engine control module can interfere with the sensor's readings, leading to this code. 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 P00E2 Description

The P00E2 diagnostic trouble code (DTC) refers to the Charge Air Cooler Coolant Temperature Sensor 'A' Intermittent/Erratic. This code indicates that the engine control module (ECM) has detected a fault with the temperature sensor located in the charge air cooler circuit. The charge air cooler is responsible for cooling the air compressed by the turbocharger before it enters the engine. The coolant temperature sensor in this system helps the ECM monitor and regulate the temperature of the charge air, ensuring optimal performance and efficiency.

Common Causes of P00E2

  1. Faulty Sensor: The most common cause of this code is a malfunctioning charge air cooler coolant temperature sensor.
  2. Wiring Issues: Corrosion, damage, or loose connections in the sensor's wiring can also trigger this code.
  3. ECM Malfunction: A fault in the engine control module can interfere with the sensor's readings, leading to this code.
  4. Coolant Leak: A coolant leak in the charge air cooler system can affect the sensor's performance and trigger the code.
  5. Environmental Factors: Extreme temperatures or harsh driving conditions can also impact the sensor's accuracy and trigger this code.

Symptoms of P00E2

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
  2. Reduced Engine Performance: The engine may experience a loss of power, hesitation, or rough idling due to incorrect temperature readings.
  3. Poor Fuel Economy: A faulty temperature sensor can lead to inefficient fuel delivery, resulting in decreased fuel efficiency.
  4. Overheating: In some cases, the engine may run hotter than usual due to inaccurate temperature readings from the sensor.

How to Fix P00E2

  1. Diagnostic Testing: Begin by using a diagnostic scanner to retrieve and record the fault codes. Perform a thorough inspection of the charge air cooler coolant temperature sensor and its wiring.
  2. Sensor Replacement: If the sensor is faulty, replace it with a new one following the manufacturer's instructions.
  3. Wiring Repair: Inspect the sensor's wiring for damage or corrosion. Repair or replace any damaged wires or connectors.
  4. Clear Codes: After completing the repairs, clear the fault codes from the ECM's memory using the diagnostic scanner.
  5. Test Drive: Take the vehicle for a test drive to ensure that the check engine light does not reappear and that the engine operates smoothly.

Cost to Fix P00E2

The cost of repairing a Charge Air Cooler Coolant Temperature Sensor 'A' Intermittent/Erratic issue can vary depending on the vehicle make and model, the location of the repair shop, and the labor rates. On average, the parts cost for a new sensor ranges from $50 to $150. Labor costs can range from $100 to $200, depending on the shop's hourly rate and the time required for the repair. Considering the average labor rates of $80 to $150 per hour, the total repair cost for this issue may range from $150 to $350. However, it's recommended to check with local repair shops for a more accurate estimate based on your specific vehicle.
