How to Fix B1367 Ignition Tach Circuit Failure
Introduction
If you’re experiencing issues with your car’s ignition tach circuit, you may be wondering how to fix it. The B1367 code indicates a failure in the ignition tach circuit, which can cause a variety of problems with your vehicle’s performance. Fortunately, with a little know-how and some basic tools, you can fix this issue yourself and get your car running smoothly again.
What is B1367 Ignition Tach Circuit Failure?
The B1367 code is a diagnostic trouble code (DTC) that indicates a failure in the ignition tach circuit. This circuit is responsible for measuring the engine’s RPM and sending that information to the engine control module (ECM). When the ECM receives this information, it uses it to control the engine’s performance, including fuel injection, ignition timing, and more.
When the ignition tach circuit fails, it can cause a variety of problems with your vehicle’s performance. You may notice that your car is running rough, has poor acceleration, or is stalling out. In some cases, the engine may not start at all.
How to Fix B1367 Ignition Tach Circuit Failure
To fix the B1367 code, you’ll need to diagnose the problem and replace any faulty components. Here’s a step-by-step guide to help you get started:
Step 1: Check the Wiring
The first thing you should do is check the wiring for any damage or corrosion. Look for any frayed wires, loose connections, or signs of rust or corrosion. If you find any issues, repair or replace the affected wiring.
Step 2: Check the Ignition Coil
Next, check the ignition coil for any signs of damage or wear. The ignition coil is responsible for generating the spark that ignites the fuel in the engine. If the coil is faulty, it can cause the ignition tach circuit to fail. Use a multimeter to test the resistance of the coil. If the resistance is outside of the manufacturer’s specifications, replace the coil.
Step 3: Check the Crankshaft Position Sensor
The crankshaft position sensor is another component that can cause the ignition tach circuit to fail. This sensor is responsible for measuring the position of the crankshaft and sending that information to the ECM. If the sensor is faulty, it can cause the engine to run poorly or not start at all. Use a multimeter to test the resistance of the sensor. If the resistance is outside of the manufacturer’s specifications, replace the sensor.
Step 4: Check the Camshaft Position Sensor
The camshaft position sensor is another component that can cause the ignition tach circuit to fail. This sensor is responsible for measuring the position of the camshaft and sending that information to the ECM. If the sensor is faulty, it can cause the engine to run poorly or not start at all. Use a multimeter to test the resistance of the sensor. If the resistance is outside of the manufacturer’s specifications, replace the sensor.
Step 5: Replace the ECM
If none of the above steps fix the issue, the problem may be with the ECM itself. The ECM is responsible for controlling the engine’s performance, and if it’s faulty, it can cause a variety of problems. Replace the ECM with a new one to fix the issue.
Conclusion
Fixing the B1367 code may seem daunting, but with a little know-how and some basic tools, you can get your car running smoothly again. By following the steps outlined above, you can diagnose and fix the issue yourself, saving you time and money.
FAQs
