Testing Toyotas Four Wire Ignition Coils The Low Tech Way

How To Test Ignition Coil 4 Pin Or 3 Pin Toyota Suzuki вђ Otosection Brian eslick from how to automotive howtoautomotive takes you step by step through the process of testing toyota's four wire ignition coils f. The video shows the bench testing of a 4 wire cop from a toyota corolla and toyota yaris engine. the test used an led test light , an incandescent test light.

How To Test Toyota S Four Wire Ignition Coils Low Tech You Connect the battery’s positive connection to the ignition coil’s positive side. additionally, locate the starter solenoid and connect it to the positive battery terminal. then, short the solenoid’s terminal to the location where the ignition switch connects by unplugging the ignition switch wire from the device. This case study is perfect for anyone interested in the working details of toyota lexus coil over plug ignition system, and the very similar three wire desig. Each coil uses a 4 pin connecter. if you were looking directly at each coils' 4 pins the pins would look the following: so i would call left pin 1 and right pin 4 for each ignition coil. i have a test light and can see if the voltage is switching on the connector side as well, but i thought resistance testing was wise too.

Symptom: no start. theory: the ignition system on this engine uses a distributor with three pick up coils inside and an external igniter and coil. the ecm uses the signals generated by the three pick ups to control the igniter, which controls the negative side of the coil for spark. the igniter also sends a signal back to the ecm for injector. Rough running, seemingly, after loose plug wire on cyl 4. for the secondary test you should be checking the resistance between the spark plug wire input on top of the coil and the contact in the tip of the coil that connects to the actual spark plug. resistance between these two points should be between 9.3 and 16.0 ohms on a cold coil.
