What are the advantages of using an OBD2 scanner?
Today’s cars are full of technology. When a sensor detects a problem with this technology, your car’s computer pops a code, and the check engine light usually comes on.
This light means there’s a problem somewhere in the system. But, without reading the codes from the onboard computer, you won’t have any way of knowing where the problems are. You could need a new evaporative canister vent valve, your car could be misfiring, or your car could have one of the hundreds of other issues.
With so many possibilities, you need diagnostics to pinpoint the problem. You could take your car to the mechanic for a diagnostic, but that gets expensive.
Code scanners to the rescue!
