Check Eng Light
 

I Have '93 S320 With 64,000 Miles. The Check Eng Light Is On And A Computer Check Showed Code "071" Throttle Positioning Sensor Shorted To Positive. An Aprox Cost Of $1200-1800 To Replace With New Or Rebuilt. I Am Thinking Of Having Another Computer Check Done By Another Dealer At A Cost Of $100-150 Just To Be Sure. Would It Bea Good Idea To Do Another Check, And How Important Is This Error Code. What Could Happen If I Do Not Fix This Item. How Critical Is This Sensor. Thanks, Michael
