Range A displays resistance values for the temperature range of 0 to 50 degrees C, range B displays resistance values for the 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 k 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-:
-

Vehicles with engine code AVH, AZG, item 17,

-

Vehicles with engine code BDC, item 15.

-

Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data.  

-

Generate readiness code.  See: Powertrain Management/Computers and Control Systems/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-.
