How To Test An Igniter On A Toyota Lexus Toyota Igniter 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 s. 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.
Ignition Module Lexus Ls400 4ltr 1uzfe Ucf20r 1994 1997 Here's an extract from the long video covering the toyota mr2 ignition system testing. i felt a video just covering the igniter testing would be helpful as t. 1. visually inspect the igniter for any evidence of deterioration or cracks. check for chafing, burned areas, or wire cuts in the sleeving covering the wire. the connectors ought to be securely fastened and free of corrosion and or oxidation. take a look at the igniter for hot regions. watch the igniter as it heats up. 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. Swap out the ignition coil(s): defective ignition coils (also known as “pencil” coils) are a common cause of this code, so swap out the coil on the affected cylinder(s) with the coil(s) from other cylinders. if the misfire “moves” to the cylinder(s) that had good coils previously, simply replace the defective coils. check the spark plugs:.

Modern toyota vehicles have one ignition coil for each cylinder. each coil has an integral igniter. every time the ecm sends an igt pulse to an igniter, the igniter opens the ignition coil primary circuit, and the ignition coil produces a spark for the spark plug. the ecm can control the ignition timing by controlling the igt pulse. Usually a bad or failing igniter will produce a few symptom that can alert the driver of a potential issue. 1. engine misfires and decrease in power, acceleration, and fuel efficiency. one of the first symptoms of an issue with the vehicle’s igniter is engine performance issues. if the igniter fails or has any problems it can compromise the.
