●Testing method:
a Ohmmeter method
Using ohmmeter measure resistance. Determine if ECU sensor operates by abve engine air
intake temperate-resistance chart. Remove air intake temperature sensor, and heat sensor in
water (refer to diagram 4.3). Sensor has a corresponding resistance with different
temperature.
b Voltmeter method
Install sensor on engine, start engine. Connect voltmeter to sensor signal lead. For different
air intake temperate, voltmeter has a corresponding voltage drop. Voltage decrease as
temperature increase.
