[SOLVED] P2063 Code: Low Control Circuit Fix For Reductant/Regeneration Supply

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2063 fault code. This code indicates a problem with the Reductant Injector Air Pump, which could be faulty or have a poor electrical connection. It could also be caused by a faulty Powertrain Control Module (PCM).

The importance of repairing this issue lies in the fact that it could lead to increased emissions and reduced fuel efficiency.

The repair difficulty is moderate, with a repair time of 1.0. To fix the issue, you 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 due to the p2063 fault code.

Here are the symptoms to look out for:

  • The P2063 fault code in an automobile can cause the following symptoms: the engine light will turn on or the service engine soon warning light will appear.
  • Other symptoms include a decrease in engine performance, rough idling, stalling, and poor fuel economy.
  • Additionally, the vehicle may experience difficulty starting, and there may be a lack of power when accelerating.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P2063 fault code can be caused by a faulty reductant injector air pump, poor electrical connection, or a faulty PCM.

  • The automobile fault code P2063 can be caused by a faulty Reductant Injector Air Pump.
  • It can also be caused by an open or shorted Reductant Injector Air Pump harness.
  • Poor electrical connection in the Reductant Injector Air Pump circuit can also trigger this fault code.
  • Lastly, a faulty Powertrain Control Module (PCM) can also be a cause of the P2063 fault code.

Below are the possible fixes for the automobile fault code p2063, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code p2063, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 fault code P2063 indicates a malfunction in the fuel level sensor circuit. The diagnosis involves checking the wiring and connections, as well as testing the sensor itself.

The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the hourly rate of the auto repair shop, which is typically between $75 and $150 per hour.

Other factors that may affect the cost include the location of the repair shop and the availability of replacement parts.

The P2063 fault code is related to the reductant injector air pump control circuit.

It means that the Powertrain Control Module (PCM) has detected a malfunction in this circuit. The code specifically indicates that the reductantregeneration supply control circuit is low.

This fault code can cause issues with the vehicle’s emissions system and may result in decreased fuel efficiency.

It is important to have this issue diagnosed and repaired as soon as possible to avoid further damage to the vehicle.

What are the possible causes of the P2063 automobile fault code?

If you’re experiencing the P2063 fault code, you may notice that your engine light is on. This could be due to a faulty Reductant Injector Air Pump, an open or shorted Reductant Injector Air Pump harness, a poor electrical connection in the Reductant Injector Air Pump circuit, or a faulty Powertrain Control Module (PCM). 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’s pins.

How can I visually inspect the wiring harness and connectors related to the Reductant Injector Air Pump?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light), it could be due to a faulty Reductant Injector Air Pump. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Also, check for an open or shorted Reductant Injector Air Pump harness and poor electrical connection in the circuit. If the problem persists, it could be due to a faulty Powertrain Control Module (PCM).

Is it necessary to replace the Powertrain Control Module (PCM) to fix the P2063 fault code, or are there other solutions?

Replacing the Powertrain Control Module (PCM) may not be necessary to fix the P2063 fault code. The engine light may turn on due to a faulty Reductant Injector Air Pump, open or shorted harness, poor electrical connection, or a faulty PCM. To fix the issue, inspect the wiring harness and connectors for any damage or corrosion and check for broken or bent pins.
