Struggling with OBD ignition coil error codes? Discover how this LED ignition coil tester uses electromagnetic induction to identify bad coils instantly. Watch the demo video! LED Ignition Coil Tester、Faulty Ignition Coils
🔧 What is an Ignition Coil Tester?
When your car’s OBD system throws a generic ignition coil fault code (like P0300-P0304), it rarely specifies which coil is failing. This tool solves the mystery without removing a single spark plug!
How It Works:
- Electromagnetic Induction Detection: The tester’s sensor clamps around the ignition coil wire.
- LED Visual Feedback:
- Bright Flashing LED: Healthy coil (normal electromagnetic signal).
- No Light/Weak Light: Faulty coil (weak or no signal).
🚗 Step-by-Step Testing Guide
- Connect to OBD-II Port: Retrieve fault codes (e.g., P0301 = Cylinder 1 misfire).
- Clamp the Tester: Attach the sensor to each coil’s wiring harness.
- Observe LEDs:
- Good Coil: Rapid LED flashes.
- Bad Coil: Dim or no light.
