[SOLVED] P2064 Code: How To Fix High Control Circuit For Reductant/Regeneration

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2064 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 a sign of p2064 fault code. Here are the symptoms to look out for:

  • The P2064 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, engine misfire, rough idling, decreased fuel efficiency, engine stalling, and difficulty starting the engine.
  • It can also cause the vehicle to emit excessive smoke from the exhaust and experience reduced power while driving.
  • These symptoms can be caused by a variety of issues, including faulty fuel injectors, damaged wiring, or a malfunctioning engine control module.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2064 can be caused by a faulty reductant injector air pump, open or shorted harness, poor electrical connection, or a faulty PCM.

  • The automobile fault code P2064 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.
  • Another cause can be a poor electrical connection in the Reductant Injector Air Pump circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also trigger this fault code.

To fix the p2064 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2064, 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 fault code P2064 indicates a problem with the fuel level sensor circuit. The estimated repair time for this issue is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them 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. It is important to address this issue promptly to avoid further damage to the vehicle and ensure optimal performance.

The P2064 fault code is related to the reductant injector air pump control circuit.

It indicates that the Powertrain Control Module (PCM) has detected a malfunction in this circuit.

The code specifically points to a high voltage in the reductantregeneration supply control circuit. 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 promptly to avoid further damage to the vehicle.

What are the possible causes of the P2064 fault code?

If you’re experiencing the P2064 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 important to visually inspect the related 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) when fixing the P2064 fault code?

It is not necessary to replace the Powertrain Control Module (PCM) when fixing the P2064 fault code. The possible causes of the code include a faulty Reductant Injector Air Pump, an open or shorted harness, poor electrical connection, or a faulty PCM. To fix the issue, one 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.
