How to Fix P1267 Cylinder #2 High to Low Side Short

Introduction

If you’re experiencing the P1267 error code on your vehicle, it means that there is a problem with the cylinder #2 high to low side short. This can be a frustrating issue to deal with, but fortunately, it’s something that can be fixed with a little bit of know-how and some basic tools. In this article, we’ll walk you through the steps you need to take to fix this problem and get your vehicle running smoothly again.

Step 1: Diagnose the Problem

Before you can fix the problem, you need to diagnose it. The P1267 error code is usually caused by a short circuit in the wiring between the fuel injector and the PCM (powertrain control module). To diagnose the problem, you’ll need an OBD-II scanner. Connect the scanner to your vehicle’s OBD-II port and read the error code. If it’s P1267, then you know that the problem is with the cylinder #2 high to low side short.

Step 2: Check the Wiring

Once you’ve diagnosed the problem, the next step is to check the wiring. Start by inspecting the wiring between the fuel injector and the PCM. Look for any signs of damage, such as frayed wires or loose connections. If you find any damage, you’ll need to repair or replace the wiring.

Step 3: Check the Fuel Injector

If the wiring looks good, the next step is to check the fuel injector. Start by disconnecting the fuel injector from the wiring harness. Then, use a multimeter to check the resistance of the fuel injector. The resistance should be between 11 and 18 ohms. If the resistance is outside of this range, you’ll need to replace the fuel injector.

Step 4: Check the PCM

If the wiring and fuel injector both look good, the problem may be with the PCM. Start by disconnecting the PCM from the wiring harness. Then, use a multimeter to check the resistance of the wiring between the PCM and the fuel injector. The resistance should be less than 5 ohms. If the resistance is higher than this, you’ll need to replace the PCM.

Step 5: Replace the Faulty Component

Once you’ve identified the faulty component, the next step is to replace it. If it’s the wiring that’s causing the problem, you’ll need to repair or replace the damaged wiring. If it’s the fuel injector that’s causing the problem, you’ll need to replace it. And if it’s the PCM that’s causing the problem, you’ll need to replace it.

Step 6: Clear the Error Code

After you’ve replaced the faulty component, the final step is to clear the error code. Use your OBD-II scanner to clear the code from the PCM. Once the code has been cleared, start your vehicle and make sure that the error code doesn’t reappear.

Conclusion

Dealing with the P1267 error code can be frustrating, but with the right tools and knowledge, it’s something that can be fixed. By following the steps outlined in this article, you can diagnose and fix the problem and get your vehicle running smoothly again.
