Accelerator Pedal Position Sensor

WARNING: This page is about a different car, the 2011 Nissan Xterra. However, it is still accessible from the selected car via links, so may be relevant.

Reconnect all harness connectors disconnected.
Turn ignition switch ON.

Check voltage between ECM terminals 106 (APP sensor 1 signal), 98 (APP sensor 2 signal) and ground under the following conditions.

TERMINAL VOLTAGE REFERENCE CHART

Terminal	Accelerator pedal	Voltage
106 (Accelerator pedal position sensor 1)	Fully released	0.65 - 0.87V
106 (Accelerator pedal position sensor 1)	Fully depressed	More than 4.3V
98 (Accelerator pedal position sensor 2)	Fully released	0.28 - 0.48V
98 (Accelerator pedal position sensor 2)	Fully depressed	More than 2.0V

If NG, replace accelerator pedal assembly and go to next step.
Perform "ACCELERATOR PEDAL RELEASED POSITION LEARNING ".
Perform "THROTTLE VALVE CLOSED POSITION LEARNING ".
Perform "IDLE AIR VOLUME LEARNING ".
