Problem overview

Some Buick LeSabre owners report experiencing issues related to MAF sensor codes, which can lead to engine stalling and rough operation. These problems often stem from dirt and grime accumulation on the MAF sensor, causing it to malfunction and relay incorrect information to the vehicle's ECU. Additionally, the P0101 code, indicating a performance issue with the MAF sensor, is commonly reported, and a faulty sensor can significantly impact the vehicle's performance and efficiency. Some owners also encounter the P0102 code due to various factors, such as a contaminated MAF sensor or air flow obstructions. In cases where these issues arise, replacing the MAP sensor after addressing any sludge buildup has been noted as a practical solution, helping to restore the vehicle's proper functioning and prevent further sensor-related problems.
