Detecting Condition

DETECTING CONDITION

HINT:
- Diagnostic trouble code 41 is for the throttle position sensor circuit.
- Diagnostic trouble code 47 is for the sub-throttle position sensor circuit.
- When the connector for the throttle position sensor(s) is disconnected, diagnostic trouble code 41 or 47 is not displayed. Diagnostic trouble code 41 or 47 is displayed only when there is an open or short in the VTA signal circuit of the throttle position sensor(s).
- Signals from the throttle position sensor(s) are also input to the TRAC ECU. So when a malfunction occurs on the TRAC side, code 41 or 47 may be displayed.
