Mark1 sensors..

There may some new mr2 owners who may benefit from my sensor checkout the other day.

Radiator-the sensor on the side of the radiator tells it when the fan motors are supposed to run (fans do not run on "high" unless your relay is working)

A/c compressor (S/C ONLY)-there's a rotational sensor that inputs to the ECU

Side scoop fan-the sensor is located at the rear of the cyl head.

Water temp sensor-the EFI uses a separate sensor bolted to the back of the cyl head (2 wires)-looks like thermostat

Water Temp Sensor-this is located at the water inlet (1 wire) and very close to the dipstick, this feeds water temp to the dashboard speedometer.
