Scoupe L4-1468cc 1.5L SOHC (8 VALVE) (1991)
Intake Air Temperature Test Hook-up
1.
Measure the resistance between terminals 4 and 6.
Terminals 4: Intake air temperature output
Terminals 6: Sensor ground
Standard Values

176..................0.4
Intake Air Temperature Test
2.
Measure the resistance while heating the sensor using a hair drier. You should observe a reduction in resistance (less Ohms) in response to an
increase in temperature at the sensor.
3.
If the value deviates from the standard value or the resistance remains unchanged, replace the air flow sensor assembly.
