Air Temperature Sensor Placement and Wiring

zetec - 78

The Air Temperature Sensor inserts through and is then fastened to the air box backing plate.

This is a Bosch part. The Performance Electronics part number is 50050002. The cost is $30.

The threads on the sensor are metric (M12 X 1.5) so a jam nut with that threading is needed to secure the sensor to the backing plate.

The sensor connects to the wiring via the readily available EV1 connector ($6.50 with pigtail).
