What is P0070 fault code? What is the Ambient-Air Temperature Sensor Circuit malfunction? How do I fix the P0070 fault code What are the symptoms and causes for the P0070 fault code

What is the P0070 fault code? What does it signify?

If the powertrain controller module (PCM), detects a possible problem with the ambient sensor temperature sensor, or the sensor circuit, the fault code P0070 is recorded.

The PCM receives data collected by the ambient air temperature sensor. This data can be used to display the outside temperature or, if needed, to adjust the operation of an automatic climate control system.

The PCM will store the fault code P0070 if the information from the ambient temperature sensor is significantly different to the data from the intake air temperature and engine coolant temperatures sensors.

Your vehicle’s onboard diagnostics system could register the code P0070 if you have a Ford, specifically Ford Focus, BMW, Volkswagen, or Mini.

Depending on your vehicle type, there are some relevant fault codes:

P0071: Ambient Air Temperature Sensor Range/Performance
P0072: Low Input Ambient Air Temperature Sensor Circuit
P0073: Ambient Air Temperature Sensor Circuit High Input
P0074: Intermittent Ambient Air Temperature Sensor Circuit

 

What causes the P0070 Fault code?

  • – Defective ambient air temperature sensor
  • – Short-circuited or broken cables
  • – Corroded electrical circuits and connectors
  • – Dirty sensor

 

What are the symptoms of the P0070 Fault code?

  • – Illumination at the check engine lights
  • – Air conditioning not working properly
  • – Incorrect readings in the interior air temperature display

 

How do I fix the P0070 fault code?

  • Repair of short-circuited or broken cables
  • – Cleaning of corroded electrical circuits and connectors
  • – Clean or replace the ambient temperature sensor

 

How serious is the P0070 Fault code?

This code should not be considered serious as it won’t cause any driving problems or stop the vehicle running smoothly. Depending on the weather conditions, it may be possible for the climate control system to malfunction.
