GTI V6-2792cc 2.8L DOHC (AAA) (1996)
Fig. 1 Resistance graph
The diagram is valid for Engine Coolant Temperature (ECT) sensor -G62- and Intake Air Temperature (IAT) sensor -G72-.
Scale A shows resistance values for temperature range 0°-50°C (32°-122°F) and scale B the values for temperature range 50°-100°C (122°-212°F).
Examples:
-
30°C (86°F) corresponds to a resistance from 1500-2000 ohms.
-
80°C (176°F) corresponds to a resistance from 275-375 ohms.
If the specification is not attained:
-
Replace Intake Air Temperature (IAT) sensor -G72-.
Continuation of check when display = ambient temperature
-
Remove IAT sensor -G72- (harness remains connected).
-
Read intake air temperature value in display field 4.
-
Spray sensor with a commercially available freeze spray and at the same time observe temperature value.
-
Temperature value must decrease.
If the specification is not attained:
-
Replace Intake Air Temperature (IAT) sensor -G72-.
-
Read the readiness code. If DTC memory has been erased, verify repair via appropriate display group, Readiness code, creating. See: Powertrain
