Before electronic fuel injection (EFI) was
introduced, cars depended on mechanical adjustments to fuel flow, airflow and
even time. However, electronic control units (ECU) combined with EFI systems,
have dramatically altered the way vehicles perform.
As long as the ECU and EFI systems are
working properly, everything is in order. However, if a sensor or component
fails, and the system can go downhill fast. As these are complex systems, it’s
not as simple as replacing a part and going on your way.
In most cases, a warning light will flash
or stay on to let you know something is wrong. If so, that’s great (i.e. the
best-case scenario). However, there are times when you know something is wrong,
but no light is present.
In either case, having someone connect to
the ECU and the system components can quickly identify underlying and hidden
issues that need to be corrected.
There are plenty of over-the-counter tools
that can provide some information. However, they cannot access the deepest
parts of the computer system. For that, you need a factory diagnostic tool.
We have factory tools and readers for most
major vehicle brands. As such, we can see exactly what’s wrong. Equipped with
this information, you can avoid unnecessary and costly repairs.
