P1361 Ignition Coil A Primary Circuit Malfunction

How to Fix P1361 Ignition Coil A Primary Circuit Malfunction


If you’re experiencing engine problems and your check engine light is on, you may have a P1361 code. This code indicates that there is a problem with the ignition coil A primary circuit. Ignition coils are responsible for providing the spark that ignites the fuel in your engine. When the primary circuit fails, it can cause misfires, rough idling, and even engine stalling. In this article, we’ll show you how to fix P1361 ignition coil A primary circuit malfunction.

Step 1: Check the Ignition Coil

The first step in fixing P1361 is to check the ignition coil. Start by disconnecting the negative battery cable to prevent any electrical shock. Locate the ignition coil and check for any signs of damage or wear. If the coil is damaged, it will need to be replaced. If it looks okay, move on to the next step.

Step 2: Check the Wiring

The next step is to check the wiring that connects the ignition coil to the power source. 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 needed.

Step 3: Check the Power Source

If the ignition coil and wiring are both in good condition, the next step is to check the power source. Use a multimeter to test the voltage at the ignition coil. If the voltage is too low, there may be a problem with the power source. Check the battery and alternator to ensure they are functioning properly.
