Circuit Operation
- The PCM (terminal 124) applies 5 volts to the A/T fluid temperature sensor output terminal (terminal 1).
- The A/T fluid temperature sensor circuit is grounded to the PCM (terminal 57).
- When the A/T fluid temperature is cold, the A/T fluid temperature sensor resistance is high. When the A/T fluid temperature is hot, the A/T fluid temperature sensor resistance is low.
