  • Additionally, the vehicle may experience misfires, reduced fuel efficiency, and difficulty starting.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

There are several causes of the automobile fault code p2147, including a faulty fuel injector, open or shorted harness, poor electrical connection, and a faulty engine control module.

  • The automobile fault code P2147 can be caused by a faulty fuel injector 1.
  • It can also be caused by an open or shorted fuel injector 1 harness.
  • Poor electrical connection in the fuel injector 1 circuit can also trigger this fault code.
  • Lastly, a faulty engine control module (ECM) can also be a cause of the P2147 fault code.

To fix the p2147 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2147, 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 P2147 indicates a malfunction in the fuel injector group A supply voltage circuit. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue varies between $75 and $150 per hour, depending on the auto repair shop.

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

It is important to address this fault code promptly to avoid further damage to the vehicle and ensure optimal performance.

The P2147 code is related to the fuel injector circuit in the engine.

It indicates that the high control circuit of the fuel injector in cylinder 1 is experiencing low voltage. This means that the Engine Control Module (ECM) is unable to energize the fuel injector in cylinder 1. As a result, the affected fuel injector is disabled, which can cause issues with the engine’s performance.

The DTC will be set when the ECM detects that the fuel injector high voltage supply circuit is shorted to ground for more than 2 seconds.

What are the possible causes of the P2147 fault code?

If you’re experiencing the P2147 fault code, you may notice that your engine light is on. This code can be caused by a faulty fuel injector, an open or shorted fuel injector harness, poor electrical connection in the fuel injector circuit, or a faulty Engine Control Module (ECM). To fix this issue, it’s important to visually inspect the wiring harness and connectors, checking for any damaged components or broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P2147 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2147 fault code, there are a few possible causes to consider. One of them is a faulty Fuel Injector 1, which could be caused by an open or shorted harness, poor electrical connection, or a faulty Engine Control Module (ECM). To fix this issue, you should 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.

Is it possible for a faulty Engine Control Module (ECM) to cause the P2147 fault code?

Yes, a faulty Engine Control Module (ECM) can cause the P2147 fault code. This fault code is triggered when there is an issue with Fuel Injector 1, its harness, or the ECM. The symptom is an illuminated Engine Light or Service Engine Soon Warning Light. To fix this issue, one should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.
