WARNING: This page is about a different car, the 2010 Suzuki Kizashi. However, it is still accessible from the selected car via links, so may be relevant.

Remove accelerator pedal assembly, see Accelerator Pedal Assembly (Incorporating APP Sensor) Removal and Installation .
Check APP sensor output voltage as follows.
If faulty condition is found, replace accelerator pedal assembly (incorporated with APP sensor), see Accelerator Pedal Assembly (Incorporating APP Sensor) Removal and Installation .
1. Connect 3 new 1.5 V batteries (1) in series and check that total voltage is 4.5 - 5.0 V.
2. Connect voltmeter (2) and batteries to APP sensor as shown in figure.
