Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Ignition System: Description
The electronic ignition system consists of a breakerless distributor, an ignitor, a pick-up coil, ignition coil, and related wiring. Distributor contains a reluctor, breaker plate, and pick-up coil assembly.
Tercel (carbureted) models are equipped with vacuum and centrifugal advance mechanisms in the distributor. The vacuum advance may be controlled by a computer activated solenoid, a thermostatic switching valve, or the High Altitude Compensation (HAC) system.
Some Toyota models use an Integrated Ignition Assembly (IIA) that has the ignition coil and ignitor mounted on the distributor.
