What is igniter circuit malfunction?
This code refers to a malfunction in the ignition system, with the malfunction being the lack of an IGF (Ignition Feedback) signal between the igniter (also known as an “ignition module”), and the PCM (Powertrain Control Module).
What is IGf signal?
The IGf signal confirms that ignition has actually occurred. In the event of a failure to trigger an ignition event, the ECU will shut down injector pulses to protect the catalyst from flooding with raw fuel. Typically this failsafe shutdown occurs within eight to eleven IGt signals after the IGf signal is lost.
How do you test a Toyota ignition Control Module?
Remove one plug wire at the spark plug and insert an old spark plug into the end of the plug boot. Place the spark plug on a metal surface on the engine. Crank the engine and check for a spark at the old spark plug. No spark on the plug indicates an ignition problem.
What is a Toyota igniter?
The primary function of the igniter is to turn on and off the primary coil current based on the IGT signal received from the ECM. The igniter or ECM may perform the following functions: • Ignition Confirmation (IGF) signal generation unit.
How does a Toyota igniter work?
The igniter is an amplifier used to trigger the discharge of battery current into the primary coil windings. The coil if functional, then generates a high voltage spark through the secondary coil windings.
What is a Toyota IGF signal?
IGF (Ignition Confirmation Signal) The ECM uses the IGF signal to confirm each ignition coil has fired after it sends an IGT pulse. The ECM supplies a 5V reference voltage on the IGF circuit shared by all coils. Each time a coil fires, its igniter pulls the IGF 5V reference voltage to ground.
How do you diagnose ignition problems?
Here’s How To Diagnose Your Ignition Issues
- Verify Lack of Spark.
- Check for Any Obvious Issues.
- Probe for Power.
- Double-Check Firing Order.
- Double-Check Initial Timing.
- Test/Inspect Spark Plugs.
- Test Spark Plug Wires.
- Check for Spark at Coil.
How do you test a distributor spark?
Pull the coil wire from the distributor and hold it near a ground. Again, have your assistant crank the engine and look for spark from the coil lead. If you have spark, you likely have a problem with your distributor rotor or cap, so you may want to replace them.
