Toyota MR2 Igniter
The Toyota MR2 Igniter is an electronic switch that quickly opens and closes the coil primary circuit to provide the magnetic field collapse that generates a high voltage spark to fire the engine when you turn the key. This small control unit sits in early MR2 distributor housings and in later cars it is mounted separately and governed by the engine computer, yet its aim never changes. It times coil power with millisecond precision for strong combustion, better fuel mileage and lower emissions, helping uphold classic Toyota reliability. Similar to the distributorless ignition system, in first generation models the Igniter works with a magnetic pickup or hall sensor inside the distributor. The Igniter has its own transistor to handle current, which makes mechanical points a thing of the past. The subsequent generations, namely the second and those after that, have a distributorless setup wherein the Igniter gets data about the crankshaft and, on that basis, signals the individual coils under the direct supervision of the control computer. Therefore, there are no manual timing adjustments. The final system takes sensor feedback into account for advance, knock protection and quick starts. The Igniter is critical for many MR2 owners as it causes a Toyota MR2 to stop cold.

Toyota MR2 Igniter Parts Questions & Experts Answers
- Q: How check and replace the Igniter on Toyota MR2?A:To check the line source power voltage, use a voltmeter by connecting the positive probe to the Ignition Coil positive terminal and the negative probe to ground, ensuring approximately 12 volts is indicated when the ignition switch is turned to On. If the voltage is not present, troubleshoot the igniter circuit. For the igniter power transistor, connect the positive probe of the voltmeter to the ignition coil negative terminal and the negative probe to ground, again expecting around 12 volts; if not, replace the igniter. To further test, unplug the ignition coil wiring connector from the distributor and connect a 3 to 5-volt dry cell battery to the pink and white wire terminals, taking care not to exceed 5 volts or apply voltage for more than five seconds to avoid damage. Then, check the voltage at the ignition coil negative terminal, which should read 7 to 10 volts; if it does not, replace the igniter. For replacement, remove the coil protector, the coil primary terminal nuts and wires, unplug the two large green connectors to the igniter, and take out the two igniter mounting screws before removing the igniter. Installation follows the reverse order of removal.
