P0108 Map Limits and CVT check light after boost

Post by Akio »

My setup is HKS GT Supercharger GTS4015 running 8.8 PSI. After about 5700 RPM, the CVT triggers a check engine light with code P0108 Manifold Absolute Pressure (Map) Sensor Circuit High.

The car still drives normally, but the error appears and causes CVT limp mode.

How did you solve this problem? Did you use a MAP sensor diode (Zener) or another solution?
