Kia Cadenza: Engine Control System / ETC (Electronic Throttle Control) System Repair procedures
Throttle Position Sensor (TPS)
1.
Connect the GDS on the Data Link Connector (DLC).
2.
Start the engine and measure the output voltage of TPS 1 and 2 at C.T. and W.O.T.
Throttle angle(°) Output Voltage (V) TPS1 TPS2 C.T 0.5 4.5 W.O.T 4.41 0.59
ETC Motor
1.
Turn the ignition switch OFF.
2.
Disconnect the ETC module connector.
3.
Measure resistance between the ETC module terminals 1 and 2.
4.
Check that the resistance is within the specification.
Specification: Refer to “Specification”
1.
Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2.
Remove the air intake hose.
(Refer to Engine Mechanical System - "Air Cleaner")
3.
