How do I know if my spark module is bad?
Check to see if all of the electrodes spark when the other burners are turned to the “light” position. If the igniters spark when all of the other burner control valves are turned to the “light” position then you probably have a bad burner switch (Key 323 in the parts image below).
How do you test a spark ignition module?
How to Test an Ignition Control Module
- Remove one plug wire at the spark plug and insert an old spark plug into the end of the plug boot.
- Check for voltage at the coil positive terminal when the ignition key is on.
- Locate the ignition module positive (+) wire.
- Locate the ignition module negative (-) wire.
Where does the spark signal come from on a Toyota igniter?
The igniter receives the Ne (crankshaft position) signal from the distributor’s signal coil (sometimes called the “Hall Effect sensor”) which it uses to trigger spark during cranking and initial running. Ne is also passed through the igniter to the ecu, which uses it to determine base timing.
When to replace the igniter in a Toyota?
But if your wires, wiring to ignition coil, coil itself and the dist signal generator, and the air gap of dist are within spec, then replace the igniter.
What do you check when ignition is on in a Toyota?
Check for power on B+ in the check connector when ignition is on. That verifies EFI fuse, IG2 on ignition switch, ignition fuse and EFI relay. Check that the check engine light illuminates when ignition is on. That verifies that the ecu is receiving power, and is functioning at least enough to ground the CEL.
How does the igniter work on a Toyota 3vze?
The 3vze uses a different system, “ESA” (electronic spark advance), in which there are camshaft positions signals (G1 and G2) in addition to Ne, and those inputs connect directly to the ecu instead of the igniter. And the Ne reluctor (signal rotor) has many more teeth, giving a higher resolution crank position signal to the ecu.
