Error Code P20AC: What It Means & What To Do?
OBD Code P20AC - Reductant Metering Unit Temperature Sensor Circuit
The
trouble code P20AC can be described as Reductant Metering Unit Temperature
Sensor Circuit. The error code P20AC would start triggering when the PCM would
detect some fault in reductant metering unit temperature sensor. One thing
which you must keep in mind that its symptoms as well as causes would surely
vary as it depends upon a number of things. It is the engine computer which
would monitor the temperature of the system using the reductant metering unit
temperature sensor. Now if an implausible signal would be sent by the
temperature sensor, then it would give rise to the P20AC fault code.
Learn More About OBD Error Code P20AC
This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code. The P20AC trouble code would indicate that a reductant metering unit temperature sensor circuit which is not as per the predetermined limit has been detected by the ECM. Now when this would occur, the fault code would be stored and there would be an illumination in the malfunction indicator light.
What causes this problem with the Reductant Metering Unit Temperature Sensor Circuit?
- Defaults in the reductant metering unit temperature sensor
- Reductant metering unit temperature sensor harness is open or shorted
- Reductant metering unit temperature sensor circuit poor electrical connection
- Unusable powertrain control module
Replace/Repair These Parts To Fix Code P20AC
- Exhaust Gas
Recirculation Valve - Did you just see check engine light flashing on your
dashboard? If the computer would detect some fault with the automobile’s EGR
valve circuit, then it would set up the check engine light so that the driver
is notified about the fault. Don’t
waste time and get them replaced or else this fault code can turn up.
- Diesel Exhaust
Fluid Pump - The diesel exhaust fluid pump needs to work
properly if the transmission system has to perform. If it is not functioning,
the transmission may slip and cause harsh shifts too. Thus replace faulty pump
now and buy a new one from us!
- Engine Control
Module - Is your car engine light still staying ON after
resetting or your car engine is turning off for no reason? Then these are some
common symptoms indicating that your car engine control module is defective.
- Powertrain Control
Module - The PCM works as the central computer system in
an automobile’s mechanism. This auto part is the in charge of all the
constituents as well as the functions performed by them. Having such enormous
importance in the operation of all the parts means that any defect in it will
affect almost every aspect of a car.
- Fuel Injector
- If there is a leakage in the fuel injectors, then it might cause rise
in the fuel consumption, fuel odours around the vehicle and hard starting. You
can always rely on us as we have best auto parts for our customers.
- Electronic Control
Unit - The ECU is a major component of your car's onboard
computer. It's used to regulate many systems and subsystems in your car's
engine, drive train and other major components. Visit us to buy best quality
ECU online.

Easy Diagnosis Of Engine Error OBD Code P20AC
Here are some steps which you should follow in order to diagnose this fault code:
- Use an OBD-II scanner in order to verify that the code is present, and check for other codes for any other type of error or problem that might need attention.
- The current data along with freeze frame data are recorded, and the codes are then cleared to see if they reoccur.
- The vehicle is inspected for any problems with the wiring and connectors to check for loose connections, corrosion, or shorts.
- The tests related to the reductant metering unit temperature sensor and components may help pinpoint the problem, as well as inspection of the current sensor and cut off switch will further helping the cause.
- The P20AC error is triggered if there is a physical problem with the reductant metering unit temperature sensor circuit which could cause the engine performance to go off.
Common Mistakes When Diagnosing The P20AC Code
- There can be a failure in the reductant metering unit temperature sensor
- Defaults in the powertrain control module
- Wiring failure
