Error P1502 2000 Boxster S
Paddlekey replied to rtremaine's topic in 986 Series (Boxster, Boxster S)
Hi Nick, I had the same problem. Took it to Porsche, they swapped throttle body, etc and then they recommended I take the DME to a local repair center. I had a look inside the DME and saw one of two electrolytic capacitors leaking electrolyte. I asked the repair center to replace both caps, (100uF 40V). They said they found two poor connections in the DME and replaced the caps, they tested the unit and claimed its ok. I installed it, same problem. I then decided to do the ignition thing, by turning the ignition rapidly on and off for about 20 times. Then stared the car without waiting and was ok! I then turned off the ignition, waited a while, turned it back on, I could then hear the throttle body do its thing. I think it could be a poor relay connection on start up? For now its ok, but I will check what relays are involved during start up.
