Having problems with your Ford Windstar ?
2002 Ford Windstar . Engine light is on. took it to auto zone for a test. codes that came up was p1120 & po122 . that comes back as Thottle Position Sensor for both codes. Changed it and still not solve the problem. The problem is runs good on a flat road. But going up a step hill you lose power. Pedal to the floor does not speed up. Also drove the van with over drive up the hill when you lose power. and without it on it runs up the hill good.
Could be a wiring issue to the tp sensor its self or a problem withe the throttle body or pcm
