Optima & Magentis (Canadian) 2.7L
Turn ignition switch off. Disconnect TP sensor 3-pin harness connector. Connect a DVOM, set to ohms, between TP sensor terminals No. 1 and 2. See Fig 1. Insert a 0.0256 in. (0.65 mm) thick feeler gauge between the fixed SAS and throttle lever. See Fig 2. Loosen TP sensor mounting bolts and turn fully counter clockwise. In this position, ensure there is continuity between terminals No. 1 and 2. Slowly turn TP sensor clockwise until no continuity exists between terminals No. 1 and 2. Tighten mounting bolts to 14-22 INCH lbs. (1.5-2.5 N.m) and reconnect sensor connector. Backprobing TP sensor harness connector, connect a DVOM between TP sensor terminals No. 2 (Black/White wire) and No. 3 (Green/White wire). See Figure. Turn ignition on. Do not start car. Measure voltage with throttle in idle position. Voltage should be 250-800 millivolts. If voltage is not as specified, replace TP sensor and repeat test. Remove feeler gauge after adjustments.
