System Specifications

RESISTANCE VALUES

Injector [1] 1.2 Ohms min.

[1] Check across injector terminals.




VOLTAGE VALUES

Throttle Position Sensor



Voltage [1] 0.20-1.25 volts

NOTE:

[1] TPS voltage is checked at idle. The maximum TPS reading at idle is 1.25 volts.


ECM CONTROLLED RELAYS AND SOLENOIDS


Check the resistance of each ECM controlled relay or solenoid coil before replacing an ECM. Replace any relay or solenoid if the resistance measurement is less than 20 ohms. See ECM wiring diagrams under ELECTRICAL AND ELECTRONIC DIAGRAMS for coil terminal identification of solenoids and relays to be checked.
