  1. Have been fighting the P1502 issue scince I jump started my Boxster S (-00) after winter storage. Car would run fine with MAF disconnected => got new battery and new MAF, same problem => cleaned throttle and position sensor - same problem => disconnected the ECU for a couple of days - same problem => cycled ingition on and off - MANY times - same problem! What worked for me was - with the motor cover off, so you ca hear the throttle, turn the ignition on and off until you hear the throttle opening and closing within a second or two - thats when I got my computer to store the throttle settings! If you hear a buzz when you turn the key and a second one 15-30s later it wont work - the clicks have to be within 1-2s! So "cycling" the ignition works but you have to hear the two clicks for the computer to store the settings correctly! (in my case at least)
