¾” Box Wrench
Air Temperature Sensor (Part Number EAC 2863)
The Air Temperature Sensor (also known as “Air Intake Sensor”) is on the top side of the left-side Air Filter Housing’s “trumpet”. It took longer to write about it then to change it…
(Viewed from Left-Side)
The device is a “Thermistor” - a resistor that changes it value as ttemperature changes. It is used for the EFI system and is easy to test as covered on one of Sean Straw’s web pages (http://jaguar.professional.org/thermistor/AirTemp.php). I got mine from Motorcarsltd.com (their part number IN100393) for $22.56. Unplug the connector (try not to crack it), and use a ¾” box wrench to remove the old one and reinstall the new one. There is a copper washer there – if it looks in good shape, reuse it, otherwise get a new one. Plug the connector back on. Next project…
