THROTTLE POSITION (TP) SENSOR INSPECTION [MZR 2.3 DISI Turbo]

id0140e5802700

Voltage Inspection

Caution

•  The inspection cannot be performed with this method correctly if there is a malfunction of the APP sensor or throttle valve actuator. Verify that no DTCs related to the APP sensor or throttle valve actuator are stored before the inspection.

Note

•  The TP sensor cannot be removed as a single unit. When replacing the TP sensor, replace it together with the throttle body as a single unit.

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition to ON.

3.  Verify that the TP sensor output voltage (PID: TP1, TP2) is within the specification when the accelerator pedal is not depressed. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.3 DISI Turbo].) (See PCM INSPECTION [MZR 2.3 DISI Turbo].)

•  If verified, go to the next step.

•  If not as specified, replace the throttle body. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

4.  Start the engine.

5.  Verify that the TP sensor No.1 output voltage (PID: TP1) increases according to the accelerator opening angle when the accelerator opening angle is gradually increased. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.3 DISI Turbo].)

•  If verified, go to the next step.

•  If not as specified, replace the throttle body. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

6.  Verify that the TP sensor No.2 output voltage (PID: TP2) decreases according to the accelerator opening angle when the accelerator opening angle is gradually increased. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.3 DISI Turbo].)

•  If not as specified, replace the throttle body. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)
