Jetta L4-2.0L (AEG) (2000)
-
Perform resistance measurement on Engine Coolant Temperature (ECT) sensor -G62-.
through m.y. 1999: terminals 1 + 3
from m.y. 2000: terminals 4 + 3
Scale A shows resistance values for temperature range 0-50 °C and scale B shows the values for temperature range 50-100 °C.
Examples:
-
30 °C corresponds to a resistance from 1500-2000 ohms
-
80 °C corresponds to a resistance from 275-375 ohms
If the specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) sensor -G62- with Engine Coolant Temperature (ECT) sensor -G2-. Refer item -19- See: Powertrain
Management/Fuel Delivery and Air Induction/Locations
-
Check DTC memory. If necessary, repair any malfunctions and erase DTC memory.

-
Display readiness code. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and
Readiness Codes
If DTC memory has been erased or the Engine Control Module (ECM) was disconnected from permanent battery (B+) voltage, generate the
readiness code again. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and
Readiness Codes
If there is no malfunction in the wiring and the resistance measurement values are OK:
-
Replace Engine Control Module (ECM).
