Throttle Position Sensor: Adjustment: Sedona

Turn ignition switch off. While backprobing TP sensor 4-pin harness connector, connect a DVOM, set to volts, between TP sensor terminals No. 1 (Yellow wire) and No. 3 (Blue/White wire). See Fig 1 and Fig 2 . Turn ignition on. Do not start engine. Measure voltage with throttle in idle position. Voltage should be 300-900 millivolts. With throttle fully open, voltage should be 4.0-4.6 volts. If voltage is not as specified, loosen TP sensor mounting bolts and adjust by turning the TP sensor. Turning TP sensor clockwise increases output voltage. Make adjustments with throttle in idle position. See Fig 3. After adjustment, torque TP sensor mounting bolts to 14-22 INCH lbs. (1.5-2.5 N.m). If problem still exists, replace TP sensor and repeat test.
