Test Connector

The Test Connector is a green, one pin connector located in the engine compartment. When grounded, the test connector activates the self-diagnostic system and causes the dash mounted "CHECK" light to flash malfunction codes (California vehicles only).

Test connector signal can be checked at ECU terminal 1E. When ignition is switched "ON," MIL lamp should light for three seconds with terminal voltage reading below 2.5V. After three seconds, the MIL lamp should go out with terminal voltage now reading approximately 12V.

Crank angle sensor is part of the distributor assembly.
