Component Inspection
■ Throttle Position Sensor Inspection
1.

Ignition switch "OFF"

2.

Connect VMI to GDS and set up an oscilloscope as follow (2-channel);

Channel A (+) : Pin No. 4 (TPS1 Signal) terminal of Throttle Body.

Channel A (-) : Ground

Channel B (+) : Pin No. 5 (TPS2 Signal) terminal of Throttle Body.

Channel B (-) : Ground

3.

Ignition switch "ON" & Engine "ON"

4.

Testing Condition : Idle to Acceleration(W.O.T).

Specification : Refer to Figure below

Fig.1) Normal Throttle Position Sensor Signal waveform at idle to acceleration(W.O.T).

※ Sum of TPS1 and TPS2 signal voltage should equal to approximately 5V.

5.

Is the measured value within specification?

▶ Go to "System Inspection" procedure.

▶ Carefully re-do this troubleshooting guide steps.

▶ If no problems were found with the circuits or connectors, Throttle Body and then go to "Verification of Vehicle Repair" procedure.

caution

- Install the component with the specified torques.

- Note that internal damage may occur when the component is dropped or mis- treated.
