October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Motor Position Sensor (1.5L)
- Disconnect motor position sensor connector. See Fig 1
. Connect ohmmeter, and measure resistance between terminals No. 4 (Black wire) and No. 5 (Green/Yellow wire). Resistance should be 3500-6500 ohms.
CAUTION:
Apply only 6 volts DC or less to ISC motor connector. Higher voltage could cause ISC motor gears to lock up.
- Disconnect Idle Speed Control (ISC) motor connector. Connect 6 volts DC (four 1.5-volt DC batteries) between terminals No. 1 (Blue/Yellow wire) and No. 2 (Blue/White wire) of ISC motor connector to operate ISC motor.
- Measure resistance between terminals No. 2 (Light Green wire) and No. 4 (Black wire) of motor position sensor connector. Ensure motor position sensor resistance changes smoothly as motor extends and retracts. Resistance should change from 500 ohms to 3500-6500 ohms. If resistance is not within specification, replace ISC motor assembly.
