Download Engine Performance On-Vehicle Adjustments – 2001 Hyundai Santa Fe (2.7L) & Sonata (2.5L) 1. Turn ignition off. Disconnect TP sensor 3-pin connector. Measure resistance between TP sensor terminals No. 2 (Orange wire on Santa Fe, Black/White wire on Sonata) and No. 1 (Yellow/Black wire on Santa Fe, Green/White wire on Sonata). See Fig. 1 . Standard resistance value should be 3500-6500 ohms. If resistance is not as specified, replace TP sensor. If resistance is as specified, go to next step. 2. Measure resistance between TP sensor terminals No. 2 (Orange wire on Santa Fe, Black/White wire on Sonata) and No. 3 (Red/Orange on Santa Fe, Blue wire on Sonata). Open throttle slowly from idle position to wide-open throttle position. Resistance should change smoothly in proportion to the throttle valve opening. If resistance changes smoothly, go to next step. If resistance does not change smoothly, replace TP sensor. 3. Reconnect TP sensor connector. Using a voltmeter, backprobe sensor connector terminals No. 1 (Yellow/Black wire on Santa Fe, Green/White wire on Sonata) and No. 3 (Red/Orange on Santa Fe, Blue wire on Sonata). Turn ignition on, and measure TP sensor voltage. Voltage should be 250-800 millivolts.
