Removing Protective Sleeve

13.

Remove connector protective sleeve.
IMPORTANT:
Never check connections from the front. Connectors can get damaged and worsen the problem.
Check connections through the holes in the connector.
Connection pin numbers are printed on the connector side.

14.

Connect an ohmmeter between ignition ECU connector pin 7 to fuel injection ECU connector pin 8.

Reading: 0 ohm

If reading is different, repair wire as needed and retest. If wire is O.K. and throttle position sensor is working properly, fuel injection ECU may be
faulty.

15.

After testing, disconnect all test equipment, reconnect all connectors (including the ECU connectors) and remount all panels.
