5. Install in the reverse order of removal.

MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION

1. Connect the M-MDS to the DLC-2.

2. Switch the ignition to ON.

3. Verify that the voltage (M-MDS PID: MAP) within the specification. (See PCM INSPECTION).

BAROMETRIC PRESSURE (BARO) SENSOR REMOVAL/INSTALLATION

CAUTION:

1. Remove the PCM. (See PCM REMOVAL/INSTALLATION).

BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION

CAUTION:

1. Connect the M-MDS to the DLC-2.

2. Switch the ignition to ON.

3. Verify that the BARO sensor output voltage (M-MDS PID: BARO) is within the specification.

(See PCM INSPECTION).

THROTTLE POSITION (TP) SENSOR REMOVAL/INSTALLATION

CAUTION:

1. Remove the throttle body. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION).

THROTTLE POSITION (TP) SENSOR INSPECTION

CAUTION:

1. Connect the M-MDS to the DLC-2.

2. Switch the ignition to ON.

3. Verify that the TP sensor output voltage (M-MDS PID: TP1, TP2) is within the specification. (See PCM INSPECTION).

ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION

CAUTION:

1. Connect the M-MDS to the DLC-2.

2. Switch the ignition to ON.

3. Verify that the APP sensor output voltage (PID: APP1, APP2) increases according to the increase in the accelerator opening angle when the accelerator opening angle is gradually increased.

4. Verify that the APP sensor output voltage (PID: APP1, APP2) is within the specification when the accelerator pedal is depressed and not depressed.

ACCELERATOR PEDAL POSITION (APP) SENSOR REMOVAL/INSTALLATION

CAUTION:

1. Remove the accelerator pedal. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION).
