Sub-Throttle Position Sensor Circuit, Inspection Procedure Part 3 Of 3:

CIRCUIT DESCRIPTION
This sensor detects the opening angle of the Sub-Throttle Valve and sends the appropriate signals to the ECU. If a trouble signal is input, the ECU prohibits TRAC control.

NOTE:
^ The Sub-Throttle Position Sensor signal is transmitted to the ABS & TRAC ECU from ECM, so if an error occurs at the engine side, the ABS & TRAC ECU also detects it.
If DTC No. P1400 is being output for the engine, troubleshoot the engine first.
