Inspection [07/2015 - ]: Procedure

INSPECT THROTTLE BODY

Voltage Inspection

NOTE:

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.

HINT:

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.

Connect the techstream to the DLC-2.
Switch the ignition ON (engine off).
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.
Refer to ON-BOARD DIAGNOSTIC TEST [07/2015 - ]
- If verified, go to the next step.
- If not as verified, replace the throttle body.
  Refer to REMOVAL [07/2015 - ]

Verify that the TP sensor output voltage (PID: TP1, TP2) is within the specification when the accelerator pedal is depressed and not depressed.

Refer to ON-BOARD DIAGNOSTIC TEST [07/2015 - ]

Resistance Inspection

Disconnect the negative battery cable.
Refer to REMOVAL [07/2015 - ]
Disconnect the throttle body connector.

Measure the resistance between throttle body terminals 5 and 6.

Throttle body resistance

0.3 to 100 ohms (20°C (68°F))

If not as specified, replace the throttle body.
