This article will focus on toyota’s ignition system. we’ll cover system operation, the best testing methods, and typical failures. we’ll be focusing on toyota’s direct ignition system (dis), sometimes referred to as coil on plug (cop), since that’s what you’ll find on the majority of toyota cars currently. key players. Dotting the igfs and crossing the igts. system. once you learn these, you’ll be able to quickly understand any toyota ignition system with a quick read over the information on toyota’s technical information system (tis). ne ne – (crankshaft position sensor signal) the ne signal holds information about crankshaft speed and position.
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. Fortunately there are other web resources like toyotatech’s how to find toyota ignition system faults fast! dotting the igfs and crossing the igts. according to this page “igt” (i guess “ignition trigger”) is a signal from ecu telling the coil to do its thing, and “igf” (guessing “ignition feedback”) is a signal from coil back. So let’s get started. 1. verify lack of spark. whether it’s a misfire or a no run condition, you want to make sure that lack of spark is your issue. to do so, you want to check to see if the. Typical indicators of a failed system include: loss of engine power – any problems with the ignition system mean a loss of engine power, due to voltage that’s not delivered to plugs to ignite the air and fuel mixture. this can be from worn or fouled spark plugs, fraying in spark plug wires, or damage to coils and coil packs requiring you to.

The document discusses toyota's ignition systems, providing an overview of key components and signals. it describes toyota's consistent approach to ignition systems over different model years, making the signals and parts easy to understand. the summary discusses: 1) key ignition system components like the crankshaft position sensor, camshaft position sensor, knock sensor, ignition timing. Step 1 identify the type of ignition system to be tested, most cars, use a coil over plug (cop) type of system, there are several variations but all work on the same principal. step 2 when checking for a misfire while the engine is still running, the fuel pump must be disabled to avoid accidental ignition discharge.
