APP Sensor Signal Inspection

Note. This procedure is to inspect the abnormalities of the APP sensor full closed position. Other failures than full closed position will store a DTC, therefore the steps to inspect them are not included in this procedure. Check for Temporary DTCs or DTCs with the HDS before this procedure. If there are any DTCs indicated, troubleshoot them first, then do this procedure. Press the accelerator pedal several times, and check the operation. If it does not operate properly, check the accelerator pedal. If you find a problem, replace the accelerator pedal assembly (see ACCELERATOR PEDAL REMOVAL/INSTALLATION ).
