MAP/MAF, Engine Coolant Temperature (ECT), Intake Air Temperature (IAT), Throttle Position Sensor (TPS), and the Oxygen Sensor ( O2cap O sub 2 2. Typical 4S-FE ECU Connector Configuration

Use a paperclip or a jumper wire to connect terminal to terminal E1 . Armed with the pinout table above, you can

A: It is usually located under the hood, near the passenger side strut tower, labeled "DIAGNOSTIC".

The 4S-FE engine management system is built around a robust ECU featuring a 26-pin, 16-pin, and 12-pin terminal structure, for a total of 54 pins. These pins handle 19 input signals from various sensors and 11 output signals to actuators, giving the ECU full control over the engine's operation.

When tracing the pinout for a 4S-FE, you will typically find these standard Toyota terminal codes: : Switched battery power (12V) through the EFI main relay. : Constant battery power (12V) for memory backup. E1 / E01 / E02 : Main computer grounds. : Sensor ground (return path for sensors like THW and THA). : Fuel injector signals. : Ignition timing signal to the igniter. : Ignition feedback signal from the igniter. : Crankshaft/Engine speed signal. : Engine coolant temperature sensor signal. : Intake air temperature sensor signal. : Manifold absolute pressure (MAP) sensor power and signal. : Oxygen sensor signal. : Starter signal (indicates the engine is cranking). : Vehicle speed sensor signal.

Receives ignition-switched power coming directly from the EFI Main Relay. This turns the ECU on when the key is rotated to the "ON" position.
