What does code P0072 mean?
What does code P0072 mean?
Ambient Air Temperature Sensor Circuit Low
OBD-II Code P0072 is defined as a Ambient Air Temperature Sensor Circuit Low. The ambient temperature sensor helps the engine control module (PCM) determine how much fuel to use on startup.
How do I fix code P0070?
What repairs can fix the P0070 code?
- Repairing broken or shorted wires.
- Cleaning corrosion from connector and/or electric circuitry.
- Replacing the ambient air temperature sensor.
How do you fix P0072?
What repairs can fix the P0072 code?
- Repairing or replacing wires that have broken or shorted.
- Clearing the electric circuitry and/or connector from corrosion.
- Replacing the ambient air temperature sensor.
Why is the p0072 air temperature sensor low?
Overhead console may not read outside temperature accurately Potential causes of a P0072 trouble code may include: Open in the signal circuit to the AAT sensor Open in the ground circuit to the AAT sensor A good starting point is always to check for technical service bulletins (TSB) for your particular vehicle.
What does trouble code p0072 mean on PCM?
If the P0072 trouble code returns immediately, the ambient air sensor will need to be replaced. If the P0072 trouble code takes some time before it returns, this indicates that there may be an intermittent problem with the voltage going to the PCM, which will require further diagnosis.
What does the p code mean on a check engine light?
Step 2: Determine the meaning of the letter. There are four possible letters that can be displayed in the first section. The letter “P” indicates powertrain-related codes such as those involving the engine or the transmission and their sensors. Typically, “P” codes are the only ones that will illuminate the Check Engine Light.
How does the OBD-II diagnostic trouble code work?
Depending on the type of vehicle these are some related OBD-II Diagnostic Trouble Codes: The power control module (PCM) and the ambient air temperature sensor work together to ensure the ambient air temperature does not reach levels that are higher than the intake air temperature.
Overhead console may not read outside temperature accurately Potential causes of a P0072 trouble code may include: Open in the signal circuit to the AAT sensor Open in the ground circuit to the AAT sensor A good starting point is always to check for technical service bulletins (TSB) for your particular vehicle.
What does the p0073 OBD-II Diagnostic Code mean?
Depending on the type of vehicle these are some related OBD-II Diagnostic Trouble Codes: What the P0073 code means. The Power Control Module (PCM) uses information that it receives from the ambient air temperature sensor to regulate the levels of the ambient air temperature and intake air temperature.
If the P0072 trouble code returns immediately, the ambient air sensor will need to be replaced. If the P0072 trouble code takes some time before it returns, this indicates that there may be an intermittent problem with the voltage going to the PCM, which will require further diagnosis.
What are the codes for the Check Engine light codes?
P0065 Air Assisted Injector Control Range/Performance P0066 Air Assisted Injector Control Circuit or Circuit Low P0067 Air Assisted Injector Control Circuit High P0071 Ambient Air Temperature Sensor Range/Performance P0072 Ambient Air Temperature Sensor Circuit Low Input P0074 Ambient Air Temperature Sensor Circuit Intermittent
