Code P0072 Chrysler Description
The P0072 Chrysler code indicates that there is a problem with the ambient air temperature sensor circuit, specifically that the sensor is reading a lower voltage than expected. The ambient air temperature sensor is responsible for measuring the temperature of the air outside the vehicle, which is crucial for various systems such as the engine management system, climate control system, and transmission control system. When the sensor circuit is reading a low voltage, it can lead to incorrect temperature readings being sent to these systems, resulting in poor engine performance, reduced fuel efficiency, and potential issues with the vehicle's emissions.
Common Causes of P0072 Chrysler
- Faulty ambient air temperature sensor
- Wiring or connector issues in the sensor circuit
- Corrosion or damage to the sensor
- Electrical issues in the sensor circuit
- Faulty engine control module (ECM)
Symptoms of P0072 Chrysler
- Check engine light is illuminated
- Inaccurate temperature readings on the climate control system
- Engine running rough or stalling
- Reduced fuel efficiency
- Transmission shifting issues
How to Fix P0072 Chrysler
- Begin by locating the ambient air temperature sensor, usually located near the front bumper or behind the grille.
- Inspect the sensor and its wiring for any visible damage or corrosion.
- Test the sensor using a multimeter to check for proper voltage readings.
- If the sensor is faulty, replace it with a new one.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0072 Chrysler
The cost of repairing the ambient air temperature sensor circuit low issue can vary depending on the specific cause of the problem. On average, the cost of a new ambient air temperature sensor ranges from $20 to $50, while labor costs can range from $80 to $150 per hour. Therefore, the total repair cost can range from $100 to $300 or more. It's important to consider additional diagnostic fees and potential costs for any additional parts or repairs that may be needed.
