Jetta L4-2.0L (BEV) (2004)
Range A displays resistance values for temperature range of 0 to 50 degrees C, range B displays resistance values for temperature range of 50 to 100
degrees C.
Read-out examples:
-
30 degrees C is in range A and corresponds to a resistance of 1.5 to 2.0 kilo Ohms
-
80 degrees C is in range B and corresponds to a resistance of 275 to 375 Ohms
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) sensor -G62- with Engine Coolant Temperature (ECT) sensor -G2-.
WARNING:
-
The cooling system is under pressure.
-
Danger of scalding when opening.
-
Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data. See: Testing and Inspection/Scan Tool
Testing and Procedures/With Generic Scan Tool/Diagnostic Mode 4: Reset/Erase Diagnostic Data
-
Generate readiness code. See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes.
If no malfunctions are detected in the wires and the resistance values are OK:
-
Replace Motronic Engine Control Module (ECM) -J220-.
Function test, vehicles with engine code AVH, AZG, BBW, BEV
-
Connect diagnostic tester. See: Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Scan Tool Connecting/Diagnostic Tester,
Connecting
-
Switch ignition on.
-
Under address word 33, select "Diagnostic mode 1: Check measured values."
-
Select measuring value "PID 05: Coolant temperature".
-
Check specified value of coolant temperature:
If specified value is not obtained:
-
Continue test according to the following table:
If specified value is obtained:
-
Start engine and let run at idle. The temperature must climb uniformly
