2001 x5 4.4 starts then dies.....HELP!!!!
 

my 2001 x5 4.4 will start then dies everytime, throwing these codes:

P0120 = Throttle/Pedal Position Sensor/Switch "A" Circuit
P0121 = Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance
P0123 =Throttle/Pedal Position Sensor/Switch 'A' Circuit High
P0223 = Throttle/Pedal Position Sensor/Switch 'B' Circuit High


I replaced the pedal assembly and throttle body with new equipment, I also replaced the DME with one from ecudoctors.com ......same thing!! .HELP!!!

someone please text me or email me!

There was a throttle calibration reset somewhere by Killcrap. Something like you putting in the key, and flooring the car without starting, holding it there for a while, then i don't remember.

Have you checked for air leaks.

Here's one of the versions ....http://www.xoutpost.com/articles/x5/...-ms43-edk.html

I tried this throttle adaptation multiple times.......no success?
 

no success. The car will start and shut off, if I try to use the throttle theres no response. And Im assuming thats what those throttle pedal codes mean too. Im stumped :(

WHEN i TURN THE KEY FORWARD I DO HEAR the throttle flap open and close once but thats it.

my truck is a 2001 4.4
 

maybe theres a different process for the v8?

Yes, try flooring it while it opens the throttle, then start the car with foot still on throttle.

to set adaptations? is that what you mean? because flooring it does nothing since the throttle doesnt work at all

I am really not sure what else to suggest. Can you connect to gt1/dis? Something other than a regular scanner.

Im going to look at it with carsoft today. wondering if theres a loose wire, harnesses look good.

Could be a dirty throttle plate. See this video in it entirety.
