Inspection
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”
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 (A).
4. | Remove the installation bolts, and then remove the ETC module (A) from the engine.
Installation
• | Install the component with the specified torques.
• | Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
1. | Installation is reverse of removal.
Electronic throttle body Installation bolt: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Adjustment
ETC module learning procedure
When installing new ETC module or re-installing it, ETC module learning procedure must be performed.
1. | Hold the ignition key or the start button at th IG ON position during 5 seconds.
2. | Turn ignition swich OFF and then start the engine.
DTC codes (P0638, P2110) might be displayed if ETC module learning procedure does not performed after replacing ETC module.
