Sub-Throttle Position Sensor Circuit, Inspection Procedure Part 5 Of 5:

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:
^ After the inspection, clear the DTC.
^ The Sub-Throttle Position Sensor signal is transmitted to the TRAC ECU from ECM, so if an error occurs at the engine side, the TRAC ECU also detects it.
If DTC No. P1400 or P1401 is being output for the engine, troubleshoot the engine first.
