P1101 Diagnostic Issue on 2011 Chevrolet Cruze - No Sensor Faults Detected
I recently encountered a P1101 diagnostic trouble code on my 2011 Chevrolet Cruze. Despite comprehensive testing of all relevant sensors, including the Mass Air Flow (MAF) sensor, all readings appear within normal range and show correct voltage output at idle, 2500 RPM, and 4000 RPM. The vehicle runs smoothly with no noticeable performance issues. However, the P1101 code persists in the history. I'm seeking advice on possible causes or next steps to resolve this issue without sensor replacement.
Could you please share your freeze frame data? Specifically, what is the MAF signal reading at idle, 2500 RPM, and 4000 RPM? This information may help identify any inconsistencies in airflow or engine load that could be triggering the P1101 code.
