DIAGNOSIS

1. OVERVIEW AND LOCATION

The throttle body is installed for the vehicle with D27DTP (POWER UP) engine and D27DT engine with CDPF.
However, its function in each engine is different as follows:

engine

D27DT + CDPF

Function

Preventing the engine from turning off with flutter-
ing noise by blocking the intake air with the flap in
the throttle body when the engine is switched off

Increasing the temperature of the exhaust gas by
minimizing the intake air volume if the engine is in
the low-load range and CDPF is being recycled

Control type

Electric signal of engine ECU
(ON/OFF)

Vacuum ON/OFF control via
vacuum modulator controlled
by engine ECU

- Perform the diagnosis when the ignition is turned on.

- Defective intake throttle drive circuit (ECU pin #A75,

A77)

- Check pin (refer to P213C).

- Sensor specification: Refer to P213C.

- Actions

• Check the throttle valve and sensor wiring harnesses.

• Visually check the unit and replace if necessary.

- Causes

• The difference between throttle position de-

mand (MAP) and throttle position feedback sig-
nal is out of +5% or -13%.

- Defective throttle control (P213B)

- Defective throttle signal (P213C, P213D)

- Defective throttle drive (P2103, P2101, P2102,

P2104, P2100)

- Check pin (refer to P213C).

- Sensor specification: Refer to P213C.

- Actions

• Check the throttle valve and sensor wiring harnesses.

• Visually check the unit and replace if necessary.

- Causes

• The throttle valve position sensor signal is stuck

low.

- Check pin for the followings:

• Throttle valve #1: sensor (Power) ECU #A20

• Throttle valve #2: sensor (Signal) ECU #A22

• Throttle valve #3: sensor (GND) ECU #A81

• Throttle valve #4: valve (Positive) ECU #A75

• Throttle valve #5: valve (Positive) ECU #A77

- Sensor & Motor SPEC

• Motor

* Power: 12V

* Max. current : 6.8A (Normal: 3.6 ~ 0.2)

* Motor resistance: 4.3

Ω

• Sensor

* Power: 5V

- Actions

• Check the throttle valve and sensor wiring

harnesses. (The signal output of throttle valve
is below than 0.24 V.)

• Visually check the unit and replace if necessary.

- Causes

• The throttle valve position sensor signal is stuck

high.

- Check pin (refer to P213C).

- Sensor specification: Refer to P213C.

- Actions

• Check the throttle valve and sensor wiring harnesses.

• Visually check the unit and replace if necessary.

Ú

Ú

Ú Preceding Work: Remove the engine acoustic cover.

* When installing the

throttle body, replace
the O-ring with new one.

1. Disconnect the connector of the throttle body.

Removal and Installation

2. Remove the intercooler outlet duct.

3. Unscrew three mounting bolts and remove the throttle

body assembly (tightening torque: 10 ± 1.0 Nm).

4. When installing, clean the mating surface of the in-

take manifold (throttle body) and be careful not to
damage the new O-ring.

Tightening torque: 6 ~ 7 Nm
