How to Fix P1364 Ignition Coil D Primary Circuit Malfunction

Introduction

If you’re experiencing a P1364 error code on your vehicle, it means that there is a problem with the ignition coil D primary circuit. This can cause your engine to misfire, run rough, or even stall. Fortunately, fixing this issue is relatively simple and can be done at home with a few basic tools. In this article, we’ll walk you through the steps to fix P1364 ignition coil D primary circuit malfunction.

Step 1: Check the Ignition Coil

The first step in fixing P1364 is to check the ignition coil. Start by locating the ignition coil on your vehicle. It’s usually located near the engine and has a wire harness connected to it. Once you’ve located the ignition coil, use a multimeter to check the resistance of the primary and secondary windings. The resistance should be within the manufacturer’s specifications. If the resistance is outside of the specifications, you’ll need to replace the ignition coil.

Step 2: Check the Wiring

If the ignition coil checks out, the next step is to check the wiring. Start by inspecting the wiring harness for any damage or corrosion. If you find any damage, repair or replace the wiring as necessary. Next, use a multimeter to check the continuity of the wiring. Make sure that there is continuity between the ignition coil and the PCM (powertrain control module). If there is no continuity, you’ll need to repair or replace the wiring.

Step 3: Check the PCM

If the ignition coil and wiring check out, the next step is to check the PCM. Start by disconnecting the PCM and inspecting the connectors for any damage or corrosion. If you find any damage, repair or replace the connectors as necessary. Next, use a multimeter to check the continuity of the wiring between the PCM and the ignition coil. Make sure that there is continuity between the two. If there is no continuity, you’ll need to repair or replace the wiring.

Step 4: Replace the PCM

If all else fails, the final step is to replace the PCM. This is a last resort and should only be done if all other options have been exhausted. Before replacing the PCM, make sure that it is the cause of the problem by checking all other components first.

Conclusion

Fixing P1364 ignition coil D primary circuit malfunction is relatively simple and can be done at home with a few basic tools. Start by checking the ignition coil, then move on to the wiring and PCM if necessary. Remember to always check all components before replacing the PCM.
