With the tabular display system, you see the answers you need organized in a way to help you get the fastest route to a diagnosis and repair.

As you can see in this Real Fix, the most common part replaced was the Mass Airflow Sensor, and that was part was most commonly replaced at 125,000 miles.

3. The Real Fix Tip Itself

The Real Fix Tip shows the Complaint, Cause and Correction for the vehicle problem, and includes any symptoms the customer may have experienced. As you can see in this Real Fix Tip, the customer complained that their 2001 Chevy Tahoe’s check engine light was on and the engine lacked power intermittently.

The Cause shows the diagnostic process forhipble. In this example, the technician used the scan tool and found fault code P0101, which pointed them in the direction of the mass airflow (MAF) sensor. The technician then used the scan tool to find that the MAF sensor’s parameters were out of the specified range, which again pointed the tech to an issue with the MAF sensor. The technician confirmed there were no faults with the circuits going from the powertrain control module to the MAF sensor and was able to confidently diagnose that the issue was a faulty MAF sensor.

The Correction section shows what the technician repaired and/or replaced to resolve the problem, as well as confirmation of the repair. The Real Fix Tip above explains that the technician replaced the MAF sensor, cleared the codes and confirmed the vehicle operated properly with a road test.
