Kia Sportage: ETC (Electronic Throttle Control) System

Kia Sportage Third generation (SL) - (2011-2016) - Service and Repair Manual / Fuel System / Engine Control System / ETC (Electronic Throttle Control) System

Description and Operation

 Description

The Electronic Throttle Control (ETC) System consists of a throttle body with an integrated control motor and throttle position sensor (TPS). Instead of the traditional throttle cable, an Accelerator Position Sensor GAPS) is used to receive driver input. The ECM uses the APS signal to calculate the target throttle angle; the position of the throttle is then adjusted via ECM control of the ETC motor. The TPS signal is used to provide feedback regarding throttle position to the ECM. Using ETC, precise control over throttle position is possible; the need for external cruise control modules/cables is eliminated.

 Inspection

Throttle Position Sensor (TPS)

1. Connect the GDS on the Data Link Connector (DLC).

2. Stall the engine and measure the output voltage of TPS 1 and 2 at C.T. and W.O.T

Specification: Refer to "Specification"

3. Turn the ignition switch OFF and disconnect the scan tool from the DLC.

4. Disconnect the ETC module connector and measure the resistance between the ETC module terminals 1 and 2.

Specification: Refer to "Sensor Resistance"

ETC Motor

1. Turn the ignition switch OFF.

2. Disconnect the ETC module connector.

3. Measure resistance between the ETC module terminals 3 and 6.

4. Check that the resistance is within the specification

Specification: Refer to "Specification"

Removal

1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.

2. Remove the resonator and the air intake hose (Refer to "Intake And Exhaust System" in EM group).

3. Disconnect the ETC module connector.

4. Disconnect the coolant hoses (B).

5. Remove the installation bolts (A), and then remove the ETC module from the engine.
