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.
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.
What is the ignition system in a 1987 Toyota?
The 1987 Toyota ignition system consists of the distributor — which houses the coil and crank sensor — ignition igniter and the engine computer. The crank sensor sends a signal relating the position of the crankshaft relative to top dead center on compression stroke to the engine computer.
What does the igniter do on a Toyota Camry?
The Igniter (which is another name for the ignition control module) is the component that activates the ignition coil to start sparking away. When this bad boy fails, your Toyota Camry is not gonna’ start due to a lack of spark (at all four cylinders).
What happens when the ignition fails in a Toyota?
When the ignition system fails in a Toyota, generally it’s because the igniter transistor has gone south. To confirm your diagnosis, the crank sensor and the coil should be checked in the process of elimination.
Where is the spark plug on a 1993 Toyota pickup?
Google 1993 toyota pickup service manual and it should be at or near the top. I’m assuming you have good plug wires, cap, rotor & plugs, and that you are experienced in checking spark. Check for power on B+ in the check connector when ignition is on.
What happens if the IGT signal fails to reach the igniter?
If the IGT signal from the ecu fails to make it to the igniter for some reason (including the possibility of the IGT circuit within the igniter having failed), the igniter can continue to fire spark based only on Ne, which means there is no advance.
Is there a problem with the ignition coil igniter?
I replaced the coil and igniter from a wrecking yard. I still have the same problem. I just went through the ignition system and did the resistance checks that were listed. The Chilton’s manual, which sucks, said that there should be no continuity between the negative terminal on the coil and the body of the igniter.
