The P2041 automobile fault code indicates a problem with the Reductant Injection Air Pressure Sensor or its related components. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause could be a faulty sensor, open or shorted harness, poor electrical connection, or a faulty pump assembly. The repair importance is high as it affects the vehicle’s emissions system. The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2041 fault code.

Here are the symptoms to look out for:

  • The P2041 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, engine stalling, rough idling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience difficulty starting, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2041 can be caused by a faulty sensor, poor electrical connection, or a faulty pump assembly.

  • The automobile fault code P2041 can be caused by a faulty Reductant Injection Air Pressure Sensor.
  • It can also be caused by an open or shorted Reductant Injection Air Pressure Sensor harness.
  • Another cause can be a poor electrical connection in the Reductant Injection Air Pressure Sensor circuit.
  • Lastly, a faulty Reductant Pump Assembly can also trigger this fault code.

Below are the possible fixes for the automobile fault code p2041, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2041, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2041 has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of P2041 will range between $75 and $150, depending on the repair time required.

The P2041 fault 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 P2041 code is set when the voltage sent from the sensor to the PCM is out of factory specifications.

This fault code indicates an intermittent issue with the Reductant Injection Air Pressure Sensor ‘A’ Circuit.

What are the possible causes of the P2041 automobile fault code?

The P2041 fault code in automobiles is indicated by the engine light turning on. The possible causes of this fault code include a faulty Reductant Injection Air Pressure Sensor, an open or shorted harness, poor electrical connection in the sensor circuit, or a faulty Reductant Pump Assembly. To fix this issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the wiring harness and connectors related to the Reductant Injection Air Pressure Sensor?

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.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while checking the P2041 fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins while checking the P2041 fault code, follow these steps: Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins. If you find any, replace or repair them as necessary.
