Test 3 & 3A: Ignition On: Input

These tests check the following components and their circuits: closed throttle (idle) switch, throttle position sensor (TPS), MAP sensor, A/T gear selector switch, coolant temperature sensor (CTS) and MAT sensor. Coolant temperature and MAT sensors are tested in cold condition. This procedure also checks all interrelated wiring circuits as well.
