Ohms Measurments



35 Position ECU Plug:




For Terminal ID please refer to "Computers and Control Systems : Engine Control Module : Diagrams". Connector Views

CAUTION: When measuring ohms, disconnect the ECU from the harness plug and never turn the ignition key on. It is possible that failure to follow these steps will result in damage to the ECU.




Grounds



Injector Group(s)
Series resistors are included in injector Ohms measurements.



Coolant Temperature Sensor



Air Temperature Sensor



Throttle Switch



Single Injector
Series resistors are included in injector Ohms measurements.



Air Flow Sensor
1 Flap on air flow sensor closed or air tiow senor plate at rest position. Resistance increases as flap or plate opens.

2 Flap on air flow sensor opened to maximum or air flow plate deflected to maximum.

- Only applies to HOT-WIRE Air flow sensor.

- Flap on air flow sensor must be opened slightly to obtain continuity. When the flap is closedshould read infinity.
