Scoupe L4-1468cc 1.5L SOHC (8 VALVE) (1991)
Motor Position Sensor Test Hook-ups
1.
Connect an ohmmeter between terminals 1 and 4 of the motor position sensor connector.
Terminal 1: Sensor power
Terminal 4: Sensor ground
2.
Measure the resistance of the terminals.
Standard Value...4-6 Kohm
3.
Attach an ohmmeter between terminals 2 and 4 of the motor position sensor connector.
Terminal 2: MPS output
Terminal 4: Sensor ground
ISC Connector Hook-up
4.
Connect a 6V battery between terminals 1 and 2 of the ISC motor connector (to operate the ISC motor) and check to see that resistance of the MPS
(step #3 hook-up) changes smoothly when the ISC motor is activated.
5.
If the standard value is not achieved, or if the change is not smooth, replace the ISC servo assembly.
