Power steering pressure sensor- located in HIGH pressure line. Meant to slightly increase idle when parking- to make steering while parking easier. If sensor is faulty, it wont return idle. TPS bad or misadjusted? Base idle screw stop slighly bent? MINE WAS !! Base idle must be 800 rpm- or idle switch (TPS) wont be closed, ECM wont recognize idle.
