Code 148E22 means the signal feedback from one of these sensors has moved . Instead of fluctuating dynamically with throttle inputs, the voltage reads as an open loop, maximum high reference, or an outright calculation mismatch. This forces the ECU to throw an active error because it can no longer guarantee safe turbocharger or emission system operation. Common Vehicle Symptoms When diagnostic scanners reveal error code , it
