Test 3, Ignition On: Input Sensor & Switch Testing

This test checks following components and their circuits:

• Closed Throttle (Idle) Switch
• Wide Open Throttle (Wot) Switch
• Map Sensor
• A/T Gear Selector Switch
• Coolant Temperature Sensor (CTS)
• Mat Sensor.

Coolant temperature and MAT sensors are tested in cold condition. This procedure also checks all interrelated wiring circuits as well.
