P2039: Uncovering The Culprit Behind Your Car’s Fuel Pressure
The P2039 code is related to the reductant system in automobiles.
The reductant system injects a solution of urea in deionized water into the exhaust system to reduce Nitrogen Oxides (NOx) emissions. The Reductant Injection Air Pressure Sensor sends voltage reading information to the Powertrain Control Module (PCM) to interpret pressure or exhaust gas temperature. The P2039 code is set when the voltage sent from the sensor to the PCM is lower than the factory specifications.
FAQ
If you’re experiencing the P2039 fault code, your engine light may be on. This could be due to a faulty Reductant Injection Air Pressure Sensor, an open or shorted harness, poor electrical connection, or a faulty Reductant Pump Assembly. To fix the issue, check the possible causes listed above and visually inspect the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light), it could be due to a faulty Reductant Injection Air Pressure Sensor or other related issues. To visually inspect the wiring harness and connectors related to the sensor, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Reductant Injection Air Pressure Sensor harness is open or shorted, or if there is a poor electrical connection in the circuit. Once you’ve identified the issue, you can take the necessary steps to fix it.
If you find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors, follow these steps. First, check the “Possible Causes” listed above. Then, visually inspect the related wiring harness and connectors. Finally, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
Wrap Up
If you see the Engine Light ON or Service Engine Soon Warning Light with the fault code p2039, check for a faulty Reductant Injection Air Pressure Sensor, open or shorted harness, poor electrical connection, or faulty Reductant Pump Assembly. Visually inspect the wiring harness and connectors for damage and check for broken, bent, pushed out, or corroded connector’s pins.
