What is code P0070?

Diagnostic trouble code (DTC) P0070 stands for “Ambient Air Temperature Sensor Circuit.” It is logged when the powertrain control module (PCM) detects a potential issue in the ambient air temperature sensor or the sensor’s circuit.

Where is the ambient air temperature sensor?

The Ambient Air Temperature Sensor measures the temperature outside the passenger compartment and is usually mounted inside or near the front bumper.

What is the ambient air temperature sensor circuit?

Code P0073 may be set if the PCM perceives a problem with your vehicle’s ambient air temperature (AAT) sensor or the sensor’s circuit. The AAT sensor measures the air temperature outside the vehicle. It converts the temperature information into an electrical signal and sends it to the powertrain control module (PCM).

How do I fix code P0070?

What repairs can fix the P0070 code?

1. Repairing broken or shorted wires.
2. Cleaning corrosion from connector and/or electric circuitry.
3. Replacing the ambient air temperature sensor.

Why is my car reading the wrong outside temperature?

At a Glance. Your car actually has a thermistor – not a thermometer. Car thermistors are a poor representation of the actual outside temperature. This is because the thermistor is exposed to re-radiated heat from the road surface.

Is the ambient temperature?

Ambient temperature is the air temperature of any object or environment where equipment is stored. The adjective ambient means “relating to the immediate surroundings.” Also sometimes referred to as the ordinary temperature or the baseline temperature, this value is important for system design and thermal analysis.

What does an ambient air sensor do?

Thermometrics Ambient Air Temperature Sensor measures the temperature outside the passenger compartment and is usually mounted inside or near the front bumper. The sensor provides input to automatic HVAC systems to help control the interior temperature of the automobile.

How can I clear the p0070 trouble code?

In most cases, it will be required to replace the ambient air temperature sensor in order to clear the P0070 trouble code. However, it is always important to first check the wiring, connectors, and harness before concluding that the issue is the ambient air temperature sensor. Need help with a P0070 code?

What causes a p0070 code on an AAT sensor?

Potential causes of a P0070 trouble code may include: Open in the signal circuit to the AAT sensor Short to voltage in the signal circuit to the AAT sensor Short to ground in the signal circuit to the AAT sensor A good starting point is always to check for technical service bulletins (TSB) for your particular vehicle.

What is the p0070 code for a Dodge Durango?

2004 Dodge Durango P00700 code HELP! Less than 3 months ago while driving, my truck slipped and would not go past 40 mph. Got codes P00700 & P00750 Took it to transmission specialist & they said transmission looks in good shape/clean & it was: “Pressure Control Solenoid Block” & replaced the whole thing & changed th…

What is the diagnostic code for ambient air temperature sensor?

P0070 is a diagnostic trouble code (DTC) for “Ambient Air Temperature Sensor Circuit”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
