id0140b5803200

Note

•  Perform the following inspection only when directed.

Voltage Inspection

1.  Visually inspect all accelerator pedal components for looseness.

2.  Verify that the APP sensor is installed to the accelerator pedal properly.

3.  Check the power circuit voltage.

(1)  Verify that the voltage between the APP sensor terminals A (power circuit) and D (ground circuit) is 4.9—5.1 V.

4.  Verify that the voltage between the APP sensor terminals B—D, and C—D is as shown below according to the accelerator pedal conditions.

(1)  

•  If not as specified, carry out the “Circuit Open/Short Inspection.”

―   If there is no open/short circuit, replace the APP sensor. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [WL-3].)

Specification (Reference)

Accelerator pedal condition	Output voltage (V)
Fully released	0.4—0.8
Gradually depressed	Increases linearly
Fully depressed	3.4—3.8

Circuit Open/Short Inspection

1.  Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [WL-3].)

2.  Disconnect the APP sensor connector.

3.  Inspect for an open or short circuit in the following wiring harnesses.

•  If there is an open or short circuit, repair or replace wiring harnesses.
