specified range, replace MPS.
CAUTION: DO NOT apply more than 6 volts to ISC motor.
3) Operate ISC motor by connecting a 6-volt source directly
to appropriate terminals of ISC motor connector. For ISC motor
operation test procedures, see IDLE SPEED CONTROL (ISC) MOTOR
OPERATION TEST under IDLE CONTROL SYSTEM.
4) While operating ISC motor, measure resistance between MPS
connector terminals No. 3 and 5. Observe ohmmeter during ISC motor
operation. If MPS resistance does not vary within a 4000-6000 ohm
range or if resistance does not change smoothly, replace MPS (vehicles
equipped with separate MPS) or ISC motor assembly (vehicles equipped
with MPS incorporated in ISC).

1) On all models, warm engine until coolant temperature is
185-205�F (85-96�C). Disconnect oxygen sensor connector. See Fig. 3 or
4.
2) Connect digital voltmeter between terminal No. 1 and
ground. Repeatedly race engine and observe oxygen sensor output
voltage. If output is not 0.6-1.0 volt, replace oxygen sensor.
