See diagram for specified value

Range A displays resistance values for the temperature range of 0 to 65 ° C, range B displays resistance values for the temperature range of 65 to 100 ° C.

Read-out examples:

• 30 ° C corresponds to a resistance of 3790 to 4270 Ω
• 80 ° C corresponds to a resistance of 600 to 660 Ω

If specified value is not obtained:

• Replace Fuel Temperature Sensor -G81-. Refer to item 12 in Component Locations, overview (vehicles with engine code BEW)  overview of component locations.
• Erase DTC memory of control module for Diesel-Direct fuel injection system. Refer to Diagnostic mode 4: Reset/erase diagnostic data  .
• Generate readiness code.

If specified value is obtained:

• Check wires to control module according to wiring diagram. Refer to Fuel Temperature Sensor, checking  .
