Sensor ground return lines (critical for preventing signal noise on the TPS and MAP sensors).
Absolutely not. The 3S-GE has a different compression ratio, variable valve timing (on later models), and a MAP sensor vs. the AFM on most 3S-FEs. Plugging a 3S-GE ECU into a 3S-FE will destroy the engine (incorrect fuel and ignition maps). 3s-fe ecu pinout pdf
+5V constant reference voltage supplied by the ECU to power sensors like the MAP sensor and Throttle Position Sensor (TPS). Sensor ground return lines (critical for preventing signal
Because minor revisions occurred almost annually across different international markets, finding the exact documentation is paramount. Keep these tips in mind when searching for source schematics: variable valve timing (on later models)
