How to Fix P1297 Injector High Side Short to GND or VBATT – Bank 2

Introduction

If you’re experiencing the P1297 error code on your vehicle, it means that there is a problem with the high side of the fuel injector circuit on bank 2. This can cause a variety of issues, including poor fuel economy, reduced engine performance, and even engine damage if left unchecked. Fortunately, fixing this problem is relatively straightforward, and can be done with a few basic tools and some know-how.

Step 1: Check the Wiring

The first step in fixing the P1297 error code is to check the wiring on the high side of the fuel injector circuit. This can be done using a multimeter to test for continuity and resistance. Start by disconnecting the battery and removing the engine cover to gain access to the fuel injector wiring. Then, use the multimeter to test the wiring for any breaks or shorts. If you find any issues, repair or replace the wiring as necessary.

Step 2: Check the Fuel Injector

If the wiring checks out, the next step is to check the fuel injector itself. This can be done by removing the fuel rail and inspecting the injector for any signs of damage or wear. Look for cracks, leaks, or other signs of damage, and replace the injector if necessary. You can also test the injector using a fuel injector tester to ensure that it is functioning properly.

Step 3: Check the Fuel Pressure

Another possible cause of the P1297 error code is low fuel pressure. This can be caused by a faulty fuel pump, clogged fuel filter, or other issues. To check the fuel pressure, you’ll need a fuel pressure gauge and a fuel pressure test kit. Connect the gauge to the fuel rail and start the engine to check the pressure. If the pressure is low, you may need to replace the fuel pump or filter.

Step 4: Clear the Error Code

Once you’ve fixed the underlying issue causing the P1297 error code, you’ll need to clear the code from the vehicle’s computer. This can be done using an OBD-II scanner or code reader. Simply connect the scanner to the vehicle’s OBD-II port and follow the instructions to clear the code.

Conclusion

Fixing the P1297 error code is essential to maintaining the performance and longevity of your vehicle. By following these steps, you can diagnose and fix the underlying issue causing the error code, and get your vehicle back on the road in no time.
