TEST PROCEDURE

The Audi 80 with KE-III-Jetronic injection has a dual temperature sensor for the injection system and a fully electronic ignition system. Measurements at these sensors are taken from each of the two terminals to ground (cylinder block).

For testing, connect the ohmmeter to one of the two terminals and to ground (bare metal of the cylinder block).

The resistance reading depends on temperature.
