How to Fix P1296 Injector High Side Short to GND or VBATT – Bank 1

Introduction

If you’re experiencing the P1296 error code on your car, it means that there is a problem with the high side of the fuel injector circuit on bank 1. This can be caused by a short to ground or battery voltage. In this article, we’ll go over the steps you can take to fix this issue and get your car running smoothly again.

Step 1: Check the Wiring

The first thing you should do is check the wiring on the high side of the fuel injector circuit. Look for any signs of damage or wear, such as frayed wires or loose connections. If you find any issues, repair or replace the wiring as necessary.

Step 2: Check the Fuel Injector

Next, you should check the fuel injector itself. Make sure it is properly seated and connected to the wiring harness. If everything looks good, use a multimeter to test the resistance of the injector. The resistance should be within the manufacturer’s specifications. If it’s not, replace the injector.

Step 3: Check the Fuel Injector Driver Circuit

If the wiring and injector are both in good condition, the problem may be with the fuel injector driver circuit. Use a scan tool to check for any trouble codes related to the driver circuit. If you find any, follow the diagnostic procedures outlined in your car’s service manual to fix the issue.

Step 4: Check the Powertrain Control Module (PCM)

If none of the above steps have resolved the issue, the problem may be with the PCM. Use a scan tool to check for any trouble codes related to the PCM. If you find any, follow the diagnostic procedures outlined in your car’s service manual to fix the issue.

Step 5: Clear the Error Code

Once you’ve fixed the issue, use a scan tool to clear the P1296 error code. This will reset the check engine light and allow you to verify that the problem has been resolved.

Conclusion

Fixing the P1296 error code can be a bit of a challenge, but by following these steps, you should be able to diagnose and fix the issue. Remember to always consult your car’s service manual and use caution when working on your vehicle.
