The story of the Toyota 4S-FE ECU is one of survival and precision. As part of Toyota’s legendary "S" engine family, the 4S-FE was the refined, 1.8-liter workhorse often found in the JDM Toyota Corona (ST190) Toyota Chaser

Most 4S-FE ECUs utilize a three-plug system. When looking at the ECU pins (not the wire side), the plugs are generally labeled from left to right. Plug A (26-pin): Mostly engine sensors and injectors. Plug B (16-pin): Power, ground, and ignition signals.

Sensor Input Pins

IGT (Ignition Timing): Trigger signal sent to the igniter to fire the coil.
