Scale A shows resistance values for temperature range 0-50 °C and scale B the values for temperature range 50-100 °C.

Examples:

-

30 °C corresponds to a resistance from 1.5 to 2.0 k Ohms

-

80 °C corresponds to a resistance from 275 to 375 Ohms

If the specification is not obtained:

-

Replace Engine Coolant Temperature (ECT) sensor (G62).

-

Check DTC memory, if necessary, repair any malfunctions and then erase DTC memory. See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Reading Diagnostic Trouble Codes 

-

Read readiness code. If DTC memory has been erased or engine control module was disconnected from permanent positive, readiness code must
be generated again.

See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes 
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.
