How do I fix code P0073?

What repairs can fix the P0073 code?

1. Repair or replace wires that have shorts or breaks in them.
2. Absolve the electric circuitry and connector from any possible corrosion.
3. Replace the ambient air temperature sensor.

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.

How do I bypass ambient temperature sensor?

As far as the ambient sensor, that is not the MFA ambient temp sensor. This is for the A/C to make sure the compressor does not turn on on if the Sun Load is above a certain threshold to protect the compressor. This one, you can bypass if you wish. You just need to jump a wire across the sensor.

How do I test my ambient air temperature sensor?

Verify any suspicions with a visual inspection of the sensor and its connector. Use a multimeter and verify the manufacturer’s specifications (~ 220-240 ohms at 70°-80° F), to test this sensor for proper resistance. Automotive air conditioning systems use NTC sensors to monitor air temperature.

What is the symptoms of a bad temperature sensor?

Symptoms of a Bad Coolant Temperature Sensor If your vehicle starts to use a lot more gasoline than usual, or black smoke is starting to come from the exhaust pipe, these are indicators that the coolant temperature sensor in your vehicle could be defective, and needs to be replaced.

How do I know if my ambient temperature sensor is bad?

What Are the Signs of a Bad Ambient Temperature Sensor?

1. Your Car’s Auto AC Setting Doesn’t Work.
2. Your Car’s AC System Cools Your Car Inconsistently.
3. Your Car’s Outside Temperature Gauge Is Incorrect.

Why is my car reading the wrong outside temperature?

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.

What are the symptoms of a bad ambient air temperature sensor?

What Are the Signs of a Bad Ambient Temperature Sensor?

• Your Car’s Auto AC Setting Doesn’t Work.
• Your Car’s AC System Cools Your Car Inconsistently.
• Your Car’s Outside Temperature Gauge Is Incorrect.

What are the possible causes of p0073 Dodge?

P0073 DODGE Possible Causes 1 Faulty ambient air temperature sensor 2 Ambient air temperature sensor harness is open or shorted 3 Ambient air temperature sensor circuit poor electrical connection More …

What to do if the p0073 code returns?

If the P0073 code does return, we will need to test the AAT sensor and its associated circuits. Typically, there are 2 wires at the AAT sensor. With the ignition switch off, disconnect the harness going to the AAT sensor. Turn the ignition switch on.

Why is my p0073 air temperature sensor high?

If all prior tests have passed and you continue to get a P0073, this would most likely indicate a failed AAT sensor, although a failed control module could not be ruled out until the AAT sensor had been replaced. If unsure, seek assistance from a trained automotive diagnostician.

What is the OBDII code on a Dodge?

Ambient temperature sensor input voltage is above the minimum acceptable value. Engine Light ON (or Service Engine Soon Warning Light) The Powertrain Control Module ( PCM) monitors the Ambient Air Temperature Sensor. The PCM sets the OBDII code when the Ambient Air Temperature Sensor is not to factory specifications.
