The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. The reductant injection air pressure control valve is being monitored by the engine control module. This trouble code would be set by the ECM when the reductant injection air pressure control valve would not be as per the specifications set by the manufacturer.
What causes this problem with the Reductant Injection Air Pressure Control Valve Stuck Closed?
- Malfunctioning reductant injection air pressure control valve
- Reductant injection air pressure control valve harness might be unlocked
- Reductant injection air pressure control valve circuit might have bad electrical connection
- Imperfect powertrain control module
Replace/Repair These Parts To Fix Code P20AB
- Automatic Transmission Module - Sometimes the automatic transmission module is unable to communicate or correctly anticipate the speed of the vehicle and thus creates difficulty in gear shift leading to sluggish acceleration, throttle response and stalling. Thus, can also hamper a lot of components physically and thus must be check for and replaced, if required.
- Engine Control Module -
If there is any corrosion or breaks in the internal wiring of the harness, then
it can cause a short in the ECM or can also cause corrosion in the ECM through
the wiring harness. You can always rely on us as we have best auto parts for our customers.
- Powertrain Control Module -
The onboard computer, or powertrain control module is the brain of the engine
control system. Now if the brain is not working properly, then neither is the
car engine. Get it replaced before the situation gets worse.
- Fuel Injector - The fuel injectors are important component of the fuel delivery system that helps in proper utilization of the fuel entering the engine. This not only helps in taking care of the air to fuel ratios in the engine, helping the combustion process but also enhances the performance. Thus, replace faulty injector now!
- Exhaust Gas Recirculation Valve - It is auto part commonly found on many road going automobiles. It is a part of the vehicle’s exhaust gas recirculation (EGR) system, an emissions system that is designed to recirculate exhaust gases back into the vehicle’s intake so that it can reduce cylinder temperatures and NOx emissions. Purchase top notch exhaust gas recirculation valve from us at economical prices.
- Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.

Easy Diagnosis Of Engine Error OBD Code P20AB
Here are some steps which you should follow in order to diagnose this fault code:
After verifying the P20AB code with an OBD-II scanner, the mechanic should begin with a visual inspection of all electrical components, especially looking for some issues in the reductant injection air pressure control valve. Any issues should be repaired, and the code should be cleared from the system. If the code reappears after a retest, the mechanic should then move on to performing voltage tests and resistance tests on the sensor, and comparing the information to the manufacturer’s specifications. If the readings are within the correct limits, then the sensor needs to be replaced. However, if the readings are not within the correct limits, then the issue lies elsewhere. The mechanic should continue checking each possible cause, clearing the code and retesting the system after each attempt, to be sure that the correct solution is found.
Common Mistakes When Diagnosing The P20AB Code
