17. Disconnect the TPS (throttle position sensor) connector.

18. Turn the ignition switch ON (II).
19. Measure the voltage between the No. 1 and No. 3 terminals of the TPS connector.

TPS CONNECTOR

Wire side of female terminals

Is there about 5 V?

YES - Check for an open or a short in the wire between PCM connector terminal A15 and the TPS. If wire is OK, replace the TPS.

NO - Go to step 20.

20. Turn the ignition switch OFF.
21. Disconnect PCM connector A (31P).

TPS CONNECTOR

Wire side of female terminals

Is there continuity?

YES - Check for a short to ground in the wires between the No. 1 and No. 3 terminals of TPS connector and ground. If the wires are OK, replace the PCM.

NO - Go to step 23.

23. Reconnect the PCM connector A (31P) and TPS connector.
24. Disconnect the shift lock solenoid/D3 switch connector.
25. Turn the ignition switch ON (II).
26. Press the brake pedal and measure the voltage between No. 1 terminal of the shift lock solenoid/D3 switch connector and body ground.

Wire side of female terminals

Is there battery voltage when pressing the brake pedal?

YES - Go to step 27.

NO - Repair open or short in the wire between the No. 1 terminal of the shift lock solenoid/D3 switch connector and the multiplex control unit.
