Linkage Measurement CAUTION: Before attempting to test the Throttle Position Sensor (TPS), verify the linkage adjustment dimension shown in the figure above. This dimension MUST be 126.5 mm (5.0 inches) BEFORE testing. For linkage adjustment procedures, refer to Throttle Linkage Adjustment. CAUTION: Before testing the TPS, verify that the engine is set at correct low idle speed. Refer to Idle Speed Adjustment. This can be found in the Fuel Delivery and Air Induction system adjustments section. 1. After confirming the correct linkage adjustment and idle speed, proceed to the following: Throttle Position Sensor Location 2. Attach a paper clip into the center terminal of the TPS electrical connector. Do not remove the connector from the TPS for this test. 3. Attach the positive lead of a voltmeter to this paper clip and the negative lead to a good ground. 4. Turn the ignition switch to the ON position. Do not start engine. 5. The voltage at the TPS center terminal should be 1.0 volt (+/- 0.2 volt) with linkage at idle position. The voltage at the wide open throttle position
