2ND DESIGN THROTTLE SENSOR

On '83 and '84 Cressidas/Supras and '83 through '86 Camrys equipped with an Electronically Controlled Transmission (ECT), a modified sensor, which incorporates three additional signal wires designated L1, L2, and L3, is used. These signals represent throttle opening angles in between the 1.5' IDL and 70' PSW signals. The L1, L2, and L3 signals are used by the ECT system and are generated in a similar manner as the IDL and PSW signals on the 2nd design sensor. The TCCS ECU only uses the IDL and PSW signals from this sensor.
