To test the best OBD2 scanners, I used my Audi A4 Allroad vehicle while it was in the garage or on the road over a period of several weeks. Next, I measured the cord's length on the handheld scanners and the wireless range on the others. With the car running, I monitored the engine and other vital systems, and then disconnected the engine's oil temperature sensor. Finally, I checked the details provided by the scanner, fixed the problem, turned off the check engine light and erased the error code.
Then I hit the road to see if the scanner could display operating data such as engine speed, timing and coolant temperature. I paid attention to whether the device reported the data as numbers, graphs or auto-style gauges. All fault codes have four numbers and a letter prefix:. Of the roughly 5, diagnostic fault codes available, some are generic and apply to all cars, like air temperature and throttle position. For these, the numeric section starts with a 0.
Others are specific to individual carmakers and represent either a special piece of hardware or a more in-depth analysis of the problem. These start with a 1. For instance, if you get a P code, chances are there's something wrong with the engine's intake air temperature sensor. By contrast, a Ford that displays a P specialty fault code means that the intake air temperature sensor is reporting values intermittently and should be replaced.
