Inspection

Throttle Position Sensor (TPS)

1.	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.

Throttle angle(°)	Output Voltage (V)
Throttle angle(°)	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.

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).
