How to Fix P1363 Ignition Coil C Primary Circuit Malfunction
If you’re experiencing a P1363 error code on your vehicle, it means that there is a problem with the ignition coil C primary circuit. This can cause your engine to misfire, run rough, or even stall. Fortunately, fixing this issue is relatively straightforward and can be done with a few simple tools and some basic knowledge.
Step 1: Diagnose the Problem
Before you can fix the issue, you need to diagnose what’s causing it. Start by using an OBD-II scanner to read the error code. This will give you a better idea of what’s going on and where to start looking for the problem.
Step 2: Check the Ignition Coil
The most common cause of a P1363 error code is a faulty ignition coil. To check this, you’ll need to use a multimeter to test the resistance of the coil. First, disconnect the coil from the wiring harness and remove it from the engine. Then, set your multimeter to the ohms setting and touch the leads to the positive and negative terminals on the coil. The resistance should be between 0.5 and 1.5 ohms. If it’s outside of this range, the coil is faulty and needs to be replaced.
Step 3: 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 signs of damage or wear. Look for frayed wires, loose connections, or corroded terminals. If you find any issues, repair or replace the wiring as needed.
Step 4: Check the PCM
If the wiring and ignition coil are both in good condition, the problem may be with the powertrain control module (PCM). This is the computer that controls the engine and ignition system. To check the PCM, you’ll need to use a scan tool to perform a diagnostic test. This will help you identify any issues with the PCM and determine if it needs to be replaced.
Step 5: Replace the Faulty Component
Once you’ve identified the faulty component, it’s time to replace it. If it’s the ignition coil, simply disconnect the old one and install the new one in its place. If it’s the wiring or PCM, follow the manufacturer’s instructions for replacing the component.
Step 6: Clear the Error Code
After you’ve fixed the problem, use your OBD-II scanner to clear the error code. This will reset the system and ensure that the error code doesn’t come back.
Fixing a P1363 error code is relatively simple and can be done with a few basic tools and some knowledge. By following these steps, you can diagnose and fix the problem quickly and get your vehicle back on the road.
1. Can I drive my car with a P1363 error code?
It’s not recommended to drive your car with a P1363 error code. This can cause your engine to misfire, run rough, or even stall, which can be dangerous while driving.
2. How much does it cost to fix a P1363 error code?
The cost to fix a P1363 error code will depend on the cause of the problem. If it’s a faulty ignition coil, the cost to replace it can range from $50 to $200. If it’s a wiring or PCM issue, the cost can be higher.
3. Can I fix a P1363 error code myself?
If you have some basic knowledge of car mechanics and the right tools, you can fix a P1363 error code yourself. However, if you’re not comfortable working on your car, it’s best to take it to a professional mechanic.
