How to Fix P1367 Ignition Coil C Secondary Circuit Malfunction

Introduction

If you’re experiencing a P1367 error code on your vehicle, it means that there is a problem with the ignition coil C secondary circuit. This can cause your engine to misfire, run rough, or even stall. Fortunately, fixing this issue is relatively straightforward and can be done at home with a few basic tools. In this article, we’ll walk you through the steps to diagnose and fix the problem.

Step 1: Check the Ignition Coil

The first step in fixing a P1367 error code is to check the ignition coil. Start by locating the coil on your engine. It’s usually located near the spark plugs and has a wire running to it. Once you’ve found the coil, use a multimeter to check the resistance between the coil’s primary and secondary terminals. The resistance should be within the manufacturer’s specifications. If it’s not, you’ll need to replace the 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 for any visible damage or corrosion. If you find any damage, you’ll need to repair or replace the wiring. If the wiring looks good, use a multimeter to check the resistance between the coil’s secondary terminal and the PCM (powertrain control module). The resistance should be within the manufacturer’s specifications. If it’s not, you’ll need to repair or replace the wiring.

Step 3: Check the PCM

If the ignition coil and wiring check out, the problem may be with the PCM. Start by checking the PCM’s power and ground connections. Make sure they’re clean and tight. If they’re good, use a scan tool to check for any PCM error codes. If you find any, you’ll need to diagnose and fix those issues before continuing.

Step 4: Replace the Ignition Control Module

If you’ve checked the ignition coil, wiring, and PCM and still haven’t found the problem, the issue may be with the ignition control module. This module controls the ignition timing and can cause a P1367 error code if it’s malfunctioning. To replace the ignition control module, start by disconnecting the battery and removing the old module. Install the new module and reconnect the battery.

Step 5: Clear the Error Code

Once you’ve fixed the problem, you’ll need to clear the error code from your vehicle’s computer. You can do this with a scan tool or by disconnecting the battery for a few minutes. Once the code is cleared, start your engine and make sure it’s running smoothly.

Conclusion

Fixing a P1367 error code may seem daunting, but with a little know-how and some basic tools, it’s a problem that can be solved at home. By following the steps outlined in this article, you can diagnose and fix the issue and get your vehicle running smoothly again.
