P0070 Dodge Code - Ambient Air Temperature Signal Voltage Too High/Low
Quick Answer
The P0070 diagnostic trouble code (DTC) for Dodge vehicles indicates that the ambient air temperature signal voltage is either too high or too low. Common causes include Faulty Ambient Air Temperature Sensor: The sensor itself may be defective and providing incorrect voltage readings, Wiring or Connector Issues: Damaged or corroded wiring or connectors in the ambient air temperature sensor circuit can disrupt the signal, ECM Malfunction: A malfunctioning ECM may not be processing the ambient air temperature signal correctly, leading to the P0070 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 P0070 Dodge Description
The P0070 diagnostic trouble code (DTC) for Dodge vehicles indicates that the ambient air temperature signal voltage is either too high or too low. This code is typically related to the ambient air temperature sensor, which is responsible for measuring the temperature of the air outside the vehicle. The sensor provides this information to the engine control module (ECM) to help optimize fuel delivery and ignition timing based on the current environmental conditions.
Common Causes of P0070 Dodge
- Faulty Ambient Air Temperature Sensor: The sensor itself may be defective and providing incorrect voltage readings.
- Wiring or Connector Issues: Damaged or corroded wiring or connectors in the ambient air temperature sensor circuit can disrupt the signal.
- ECM Malfunction: A malfunctioning ECM may not be processing the ambient air temperature signal correctly, leading to the P0070 code.
- Environmental Factors: Extreme temperatures or exposure to moisture can also affect the sensor's performance and trigger the code.
- Other Electrical Issues: General electrical problems within the vehicle's wiring system can also impact the ambient air temperature sensor's operation.
Symptoms of P0070 Dodge
- Check Engine Light: The most common symptom associated with the P0070 code is the illumination of the check engine light on the vehicle's dashboard.
- Inaccurate Temperature Readings: The vehicle may display incorrect ambient air temperature readings on the dashboard or climate control system.
- Poor Fuel Efficiency: Incorrect ambient air temperature signals can lead to suboptimal fuel delivery, resulting in decreased fuel efficiency.
- Rough Idling: The engine may experience rough idling or fluctuations in RPM due to incorrect sensor readings.
- Engine Stalling: In severe cases, the engine may stall or have difficulty starting if the ambient air temperature sensor is malfunctioning.
How to Fix P0070 Dodge
- Diagnostic Scan: Begin by using a diagnostic scan tool to retrieve the P0070 code and any related codes to pinpoint the issue accurately.
- Inspect Sensor and Wiring: Check the ambient air temperature sensor and its wiring for any visible damage or corrosion. Replace any faulty components.
- Test Sensor Operation: Test the ambient air temperature sensor's operation using a multimeter to ensure it is providing the correct voltage readings.
- Clear Codes: After making any necessary repairs, clear the DTCs from the ECM memory using the diagnostic scan tool.
- Test Drive: Take the vehicle for a test drive to verify that the issue has been resolved and that the check engine light does not reappear.
Cost to Fix P0070 Dodge
The typical repair costs for addressing a P0070 code on a Dodge vehicle can vary depending on the specific cause of the issue. In general, replacing a faulty ambient air temperature sensor can cost between $50 and $150 for the part, with additional labor charges ranging from $80 to $150 per hour. If wiring repairs or ECM diagnostics are required, the total repair cost may increase accordingly.
