THROTTLE POSITION (TP) SENSOR INSPECTION [SKYACTIV-G 2.5T]

id0140h0802700

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.

Function Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine off).

3.  Display the PIDs TP1 and TP2. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].) (See PCM INSPECTION [SKYACTIV-G 2.5T].)

4.  Compare the voltage and opening angle indications for the PIDs TP1 and TP2 with the standard in the table indicated below.

•  If they do not match the standard, perform the voltage inspection. (See Voltage Inspection.)

Voltage Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine off).

3.  Verify that the TP sensor output voltage (PID: TP1, TP2) varies according to the accelerator opening angle when the accelerator opening angle is gradually increased. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].)

•  If verified, go to the next step.
•  If not as verified, replace the throttle body. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)

4.  Verify that the TP sensor output voltage (PID: TP1, TP2) is within the specification when the accelerator pedal is depressed and not depressed. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].) (See PCM INSPECTION [SKYACTIV-G 2.5T].)

•  If not as specified, replace the throttle body. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)
