Having a Chevrolet P2047 Code come up on your engine can be a worrying experience. This code is related to the Reductant Injector Control Circuit, and can cause the engine to run poorly or not at all. The ECM (engine control module) detects that the commanded state of the driver and the actual state of the control circuit do not match for greater than 5 seconds, leading to the code being displayed. While this code can be a major issue, luckily there are a few causes and solutions that can help you get your engine running again.
Causes and Solutions for the Chevrolet P2047 Code
| Cause | Solution |
|---|---|
| Faulty Wiring Harness | Repair or replace the faulty wiring harness |
| Defective Reductant Injector | Replace the injector with a new one |
| Faulty ECM | Replace the ECM with a new one |
| Faulty Reductant Temperature Sensor | Replace the sensor with a new one |
Faulty Wiring Harness
The wiring harness of your Chevrolet P2047 Code can be damaged due to wear and tear, or it can be damaged due to a poor connection. If the wiring harness is faulty, it can lead to a disconnection between the ECM and the reductant injector. To solve this issue, you will need to repair or replace the faulty wiring harness.
Defective Reductant Injector
The reductant injector is the component responsible for introducing the reductant into the exhaust gas stream. If the injector is defective, it can lead to the ECM not being able to control the injector, causing the code to be displayed. To solve this issue, you will need to replace the injector with a new one.
Faulty ECM
If the ECM is faulty, it can lead to the code being displayed. This is because the ECM is unable to detect the commanded state of the driver and the actual state of the control circuit. To solve this issue, you will need to replace the ECM with a new one.
Faulty Reductant Temperature Sensor
The reductant temperature sensor is responsible for measuring the temperature of the reductant. If the sensor is faulty, it can lead to the code being displayed. To solve this issue, you will need to replace the sensor with a new one.
Conclusion: Troubleshooting the Chevrolet P2047 Code
Having a Chevrolet P2047 Code come up on your engine can be a worrying experience. It can be caused by a variety of issues, such as a faulty wiring harness, defective reductant injector, faulty ECM, or faulty reductant temperature sensor. To solve the issue, you will need to replace or repair the faulty components. Thankfully, troubleshooting and repairing the Chevrolet P2047 Code is not too difficult and should not take too long to do.
