Fault Code P1125 After Tte Supercharger Mounted

[Daniel N]

Hi,

I've mounted a TTE supercharger on my IS200 from 2001. The ECU is a black box from Patrik.

I've been driving with the kit for 3 weeks and it runs great. But 2 times in those 3 weeks, the engine suddenly loose power and won't rev above 2000 RPM! Also the engine light comes up and the TRC keeps blinking.

I turn of the engine and wait 5min. Then I start it up again and now it revs and drive normally, though the engine and TRC lights are still flashing.

I've checked the faultcode with a OBD tester and it says P1125 which is Throttle control motor circuit malfunction. I've checked all the wires going into the throttle body and it looks fine.

Has anyone experienced this? Could it be something with the black box?

Your bypass cable is too tight, loosen it off a bit so you have some slack when its open.

Okey I will do that. Thanks a lot

Basically when you full throttle the bypass hits a mechanical stop and if the cables too tight it then pulls on the normal throttle body causing the code and limp mode.
