If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2038 fault code.

Here are the symptoms to look out for:

  • The P2038 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 a decrease in engine performance, rough idling, stalling, or difficulty starting the engine.
  • Additionally, the vehicle may experience poor fuel economy, reduced power, or even a complete loss of power.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2038 can be caused by a range of issues, including a faulty sensor and poor electrical connections.

  • The automobile fault code P2038 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 the P2038 fault code.

To fix the p2038 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2038, 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.
  • Ensure that all the connections are secure and free from corrosion.
  • This repair should take approximately 1.0 hour.

The automobile fault code P2038 indicates an issue with the exhaust gas temperature (EGT) sensor circuit. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P2038 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) present in the exhaust stream.

The Reductant Injection Air Pressure Sensor sends voltage reading information to the Powertrain Control Module (PCM) and the code is set when the voltage sent from the sensor to the PCM is out of factory specifications.

What are the possible causes of the P2038 fault code in an automobile?

If you’re experiencing the P2038 fault code in your automobile, you may notice that the engine light is on or the service engine soon warning light is illuminated. This fault code is typically caused by a faulty reductant injection air pressure sensor, an open or shorted sensor harness, poor electrical connection in the sensor circuit, or a faulty reductant pump assembly. To fix the issue, it’s recommended to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

How can one 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, an open or shorted harness, poor electrical connection, or a faulty Reductant Pump Assembly.
