INSPECTION

1. THROTTLE SENSOR (METHOD WITH CIRCUIT TESTER)

1. Remove the glove box. Glove Box > REMOVAL">

2. Turn the ignition switch to ON. (engine OFF)

3. Measure the voltage between ECM connector terminals.

(A)

To ECM connector

Throttle sensor	Accelerator pedal	Terminal No.	Standard
Main	Not depressed (full closed)	18 (+) and 29 (−)	Approx. 0.6 V
Main	Depressed (full opened)	18 (+) and 29 (−)	Approx. 4.0 V
Sub	Not depressed (full closed)	28 (+) and 29 (−)	Approx. 1.5 V
Sub	Depressed (full opened)	28 (+) and 29 (−)	Approx. 4.2 V

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

2. THROTTLE SENSOR (METHOD WITH SUBARU SELECT MONITOR)

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

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

Throttle sensor	Throttle opening angle signal	Standard
Main	0.0%	Approx. 0.6 V
Main	100.0%	Approx. 4.0 V
Sub	0.0%	Approx. 1.5 V
Sub	100.0%	Approx. 4.2 V

3. OTHER INSPECTIONS

1. Check that the throttle body has no deformation, cracks or other damages.

2. Check that the preheater hose has no cracks, damage or loose part.
