Accelerator pedal sensor	Accelerator pedal	Terminal No.	Standard
Main	Not depressed (full closed)	29 (+) and 33 (−)	0.3 — 1.1 V
Main	Depressed (full opened)	29 (+) and 33 (−)	2.3 — 3.8 V
Sub	Not depressed (full closed)	31 (+) and 34 (−)	0.3 — 1.1 V
Sub	Depressed (full opened)	31 (+) and 34 (−)	2.3 — 3.8 V

7. After inspection, install the related parts in the reverse order of removal.

2. CHECK ACCELERATOR PEDAL SENSOR AREA (METHOD WITH SUBARU SELECT MONITOR)

1. Turn the ignition switch to ON. (Engine OFF)

2. Read the accelerator pedal opening angle signal and voltage of accelerator pedal sensor using Subaru Select Monitor. Subaru Select Monitor > OPERATION Subaru Select Monitor > OPERATION

Accelerator pedal sensor	Accelerator pedal opening angle signal	Standard
Main	0.0%	0.3 — 1.1 V
Main	100.0%	2.3 — 3.8 V
Sub	0.0%	0.3 — 1.1 V
Sub	100.0%	2.3 — 3.8 V

3. OTHER INSPECTIONS

1. Check that the accelerator pedal does not have deformation, cracks or damage.

2. Check for smooth operation when the accelerator pedal is depressed.

3. Check if the accelerator pedal returns to its original position smoothly when the pedal is released.
