Where is the igniter located on a Toyota?
The procedures shown in this video will help you isolate the cause of a no start, no spark condition on a Toyota or Lexus system that uses an igniter built separately from the ignition coil. On 3 and 4 wire coil over plug systems, the igniter is actually built into the ignition coil. Similar procedures can be performed on those designs as well.
Where is the igniter on a coil over plug?
On 3 and 4 wire coil over plug systems, the igniter is actually built into the ignition coil. Similar procedures can be performed on those designs as well. With any no spark condition, you need to determine if you have an input or output problem.
What does the ECU do on a Lexus?
This article applies to the Lexus IS, GS, RX, ES (2004-2014). The engine control unit, or ECU, is basically the brains of your car. The ECU stores diagnostic trouble codes when it senses a malfunction so a mechanic can fix it later. It’s also the ECU’s job to store your driving data to customize your ride.
Where is the fuse puller on a Lexus ECU?
If your fuse box doesn’t have the fuse puller in it, you can use pliers for the next step. Using the diagram on the bottom of the fuse box cover, remove the EFI fuse and ETCS fuse.
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.
What is no spark advance condition on Toyota igniter?
The VAST system operation is explained on pages 6 and 8, and there is actually troubleshooting info for the no spark advance condition on page 14.
Is the distrib connection to the igniter sound?
If not, verify those and verify that the distrib connection to the igniter is sound. One member here with no spark found the trouble to be a cut brown ground wire in the engine compartment that was apparently E2. E2 is called an engine ground but it doesn’t directly connect the the engine but to the ecu, and grounds through the ecu.
What to do if your igniter is not working?
Use back-probe adapters for your multimeter or push sewing needles into the connectors and press your test leads against them. If all that checks out and you still don’t have spark, then very likely your igniter is toast. Try craigslist, ebay, or car-part.com which is a portal to hundreds of junkyards. Shouldn’t have to pay over $45 for it.
How to test the igniter on a Toyota Camry?
TEST 1: Making Sure The Igniter Is Getting Power. TEST 2: Making Sure The Igniter Is Getting Ground. TEST 3: Testing The Igniter Control Signal. TEST 4: Testing Camshaft Position Sensor 1. TEST 5: Testing Camshaft Position Sensor 2. Where To Buy The Igniter (Ignition Control Module).
