3.
Disconnect the air intake hose (A), vapor hose (B) and ETC module connector (C).
Connect the GDS on the Data Link Connector (DLC).
Start the engine and measure the output voltage of TPS 1 and 2 at C.T. and W.O.T.
Item | Opening Percentage (%) | Output Voltage (V) [Vref = 5V] | |
TPS1 | C.T | 8.5 ~ 11.5 | 0.43 ~ 0.58 |
W.O.T | 88 ~ 96 | 4.40 ~ 4.80 | |
TPS2 | C.T | 88.5 ~ 91.5 | 4.43 ~ 4.58 |
W.O.T | 2 ~ 10 | 0.10 ~ 0.50 | |
Turn the ignition switch OFF.
Disconnect the ETC module connector.
Measure resistance between the ETC module terminals 1 and 2.
Check that the resistance is within the specification.
Specification : 0.3-100 Ω [20℃(68℉)]
Turn the ignition switch OFF and disconnect the battery negative (-) terminal.
Remove the air cleaner.
(Refer to Engine Mechanical System - “Air Cleaner”)
Disconnect the air intake hose (A), vapor hose (B) and ETC module connector (C).
Remove the ETC module mounting bolts (A).
Remove the ETC module (A) after disconnecting the coolant hoses (B).
Remove the ETC Module.
(Refer to Engine Control System - "ETC System")
Keep the ETC module plate (A) open.
Clean the pollutant in the throttle body using a soft cloth moistened with clearning fluid.
Do not directly spray cleaning fluid to ETC module. Instead, use a lint free cloth moistened with cleaning fluid.
Be careful not to remove the coating fluid around the shaft. If coating fluid is removed, idling control failure may occur due to inflow of foreign substances or excessive air leakage.
After cleaning, reinstall the ETC module and then perform the ETC module learning procedure.
(Refer to Engine Control System - "ETC System" - Adjustment)
Install the component to the specified torques.
Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
When cleaning the throttle body, clean the valve and carbon at the bore using a cloth moistened with cleaner.
Do not spray the engine cleaner on the throttle body.
Be careful as fingers or cloth may get caught in the valve.
When installing the throttle body, keep foreign materials away from the throttle body.
Fill with engine coolant. (Refer to “Cooling System” in EM group).
Install in the reverse order of removal.
Electronic Throttle Control module mounting bolt :
9.8-11.8 N.m (1.0-1.2 kgf.m, 7.2-8.7 lb-ft)
Be sure to perform the ETC module learning procedure when replacing or reinstalling the ETC module.
Wait for 1 minute with the ignition switch ON.
Start the engine and keep it idle for 15 minutes.
Waif for 1 minute with the ignition switch OFF.
Restart the engine, and check that the idle speed is stable.
If the ETC module learning procedure is not performed after replacing or reinstalling the ETC module, MIL illumination with DTCs may occur.
