Hi guys , I have been away from this forum for quite a long time , so I need to introduce myself again.
My name is Laurent I own a 996 TT with 700 European HP , the car was running perfectly for 6 years now , until a few day ago
Was driving in the city ( Cannes in south of France ) when I lost the power , safe mode I guess , Max 4000 rpm showing 0,1 to 0,2 BAR Max
I turn off the car , everything went back to normal for 20 min , and it happen again this time with ABS and PSM light on , NO check engine message.
The fault code are P2135. P0222. P0121
We tried to change the throttle sensor ( under the pedal ) same problem
Disconnect the battery for a reset , same problem
Could it come from this sensor ? 99660614500
Any ideas, ?

Thank you

 

Sounds to me like the accelerator pedal potentiometer, 99660611501

I think you can log the values through durametric.

Also, check the wiring at the maf sensor, especially the ground. Sometimes the wires at the harness can back out of the pins.

 

Ok I will check that
