Touareg V10-5.0L DSL Turbo (BKW) (2004)
Terminal 2+socket 53
Wire resistance: max. 1.5ohms
-
Also check wires for short circuit to each other, to vehicle Ground (GND) and to B+.
Specified value: infinite ohms
If no malfunctions are found in wires:
-
Measure resistance between terminals on sensor.
See diagram for specified value
Range A displays resistance values for the temperature range of 0 to 50°C, range B displays resistance values for the temperature range of 50 to 100°
C.
Read-out examples:
‹› 30 °C corresponds to a resistance of 1500 to 2000 ohms
‹› 80 °C corresponds to a resistance of 275 to 375ohms
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) Sensor (G62).
CAUTION!
‹› The cooling system is under pressure.
‹› Danger of scalding when opening!
-
Erase DTC memory of Engine Control Module (ECM) --> [ Diagnostic Mode 04 - Erase DTC Memory ] See: Testing and Inspection/Scan Tool
Testing and Procedures/Diagnostic Modes 01 - 09.
-
Generate readiness code --> [ 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 Engine Control Module (ECM) (J623) --> [ Engine Control Modules, Replacing ] See: Testing and Inspection/Component Tests and
General Diagnostics/Engine Control Modules, Replacing.
