Bosch units come packaged as a complete unit. The sensing elements are paired and calibrated with the housings on the production line to ensure precise operation. Some competitors offer a simple sensing unit replacement as opposed to a complete unit. In such cases if the failure is not in the sensing unit itself, the repair may not be corrected the first time. This can cost the consumer or technician valuable time and money.

Some signs of a failed mass airflow sensor may include rough idle, a rise in fuel consumption, increased harmful emissions, and poor drivability.
