High Idle Problem

Replacing Throttle Position Sensor on Kia Sorento

On most of cases high idles are caused by one of three things -

• Faulty Throttle position sensor, 
• sticking throttle plate or 
• There is a vacuum leak.

So to confirm what is causing these high idle problem
First check all vacuum hoses for cracks/splits/breaks/disconnects and repair as needed. Clean the throttle body of all carbon buildup. If still a high idle, replace the TP sensor.

Replacing throttle position sensor is not very difficult.

Some newbie car repair techs think,there is requirement of computer reprogramming after replacing TPS. But its not required. At-least on 2005 KIA Sorento car model.



Removal & Installation for throttle position sensor:----

Disconnect the negative battery cable.
Disconnect the sensor connector.
Remove the sensor retaining screws. Remove the sensor from its mounting.

To install the new sensor:
Installation is the reverse of the removal procedure.
Now once the sensor is installed after that ,Crank engine and with all accessories off, allow to idle for 3 minutes without touching the accelerator or brake pedal.
Once these procedure is done the sensor will start operating.

These details will help.
Thanks.

Replace Oldsmobile Idle air control valve?

The details are as follows :---

Idle Air Control (IAC) Valve

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Detach the electrical connector from the IAC valve.
3. Remove the 2 attaching screws and remove the IAC valve from the engine. Remove the O-ring from the housing.

To install:

Fig. The Idle Air Control (IAC) valve is mounted on the throttle body-3.8L (VIN K) engine shown, others similar

NOTE

Before installing a new IAC valve, measure the distance that the valve is extended. The measurement should be made from the motor housing to the end of the valve cone (pintle). The distance should be no greater than 1 ¹ / ₈ inch (28mm). If the pintle is extended too far, adjustment is required, otherwise damage may occur when the IAC valve is installed. Adjust the IAC valve by compressing the pintle to achieve the correct length.

4. Use a new O-ring, install the IAC valve and tighten the retaining screws to 18 inch lbs. (2 Nm).
5. Attach the electrical connector.
6. Connect the negative battery cable.
7. The PCM will reset the IAC valve the next time the ignition switch is turnedON and then OFF .
8. Start the engine and allow to warm to operating temperature to check idle quality.

This will help.

Thanks.
