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	TPS 1	TPS 2
C.T	0.3 ~ 0.9	4.2 ~ 5.0
W.O.T	1.5 ~ 3.0	3.3 ~ 3.8

3.	Turn the ignition switch OFF and disconnect the scantool from the DLC.

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

Specification: Refer to “Specification”

ETC Motor

1.	Turn the ignition switch OFF.
