Component Inspection

THROTTLE POSITION SENSOR(TPS) INSPECTION




1. Connect a HI-SCAN to the data link connector.

NOTE: Before inspecting the TPS, complete the basic idle speed adjustment.




2. If a HI-SCAN is not used, connect a digital type voltmeter between ground and TPS output terminal.
3. Turn the ignition switch to the ON position (do not start engine) and check that TPS output voltage is as specified. If a HI-SCAN is used, read the TPS voltage.

Standard value
300 - 900 mV (2.4 L4)
250 - 800 mV (2.7 V6)

4. If it is out of specification, check that the resistance between ground and TPS output terminal is as specified.

Standard value
3.5 - 6.5 Kohm (2.4 L4)
1.6 - 2.4 Kohm (2.7 V6)

5. If it is out of specification, replace TPS with new one.

NOTE: Tighten the screws securely after replacement.
