Subsection 03
Section 05 ENGINE MANAGEMENT (DI) (COMPONENT INSPECTION AND ADJUSTMENT)
The resistance value of temperature sensor may test good at certain temperature but it might be defective at other temperaturesIf in doubt, try new sensorAlso remember this validates the operation of the sensor at ambient temperatureIt does not validate the over temperature functionalityTo test it, the sensor could be removed from the engine muffler and heated with heat gun while it is still connected to the harness to see if the MPEM will detect the high temperature condition and generate fault codeWhen working with injectors, the resistance value might test good while the complete current would not flow through the wire when pulsating current is supplied to the injector in its normal operationA solution would be to use jumper wire to directly supply the injector from the MPEMIf it now works, replace the defective wireA Noid light (available from after-market toolequipment suppliers) may also be used to validate the injector operation
