Check out out Enhanced Model U380 on Clearance for only $5.00 More!All
cars sold 1996 and later in the United States are required to interface
with a standard OBD-II (On Board Diagnostics System). This system
controls the emissions and operations of your cars engine.
This
computer is tied into the Check Engine Light on your car to alert you
that something in your cars computer is outside of its normal operating
conditions and needs service.
It can be something as simple as a loose gas cap - or a very complicated and expensive repair.
This
computer controls everything, fuel to air mixture, timing, idle speed,
shift points, and more - and this computer makes its decisions based on
dozens of sensors monitoring everything about your engines condition be
it temperature, altitude, fuel quality etc.
As we all know about computers -
the
data in is critical, if a sensor is malfunctioning, the computer cannot
make the correct decision, and your car will run poorly, and if its running bad enough, the check engine light will light up!
The key is that you must have a Diagnostic Scan Tool to access the computer to find out what sensor or component is failing.
A rough running engine could be due to bad plugs and wires, bad Oxygen Sensor, Air Filter, Mass Airflow Sensor, etc etc -
Without a Code Scanner you are just changing parts and hoping for the best - a sure waste of time and money!
Features:
Simple Push Button Operation - Nothing is needed except for the unit
LED Read out of the Fault Code - Ex. 0104
Code Book - Tells you 0104 is the Mass Airflow Sensor Circuit
Reset Button - After you have resolved the problem, reset the code and enjoy the drive
If
you do not know what is broken - you cannot fix it, certainly the first
time! If the problem looks like something too big to tackle yourself,
you now have an idea of what the problem is so that when you go to your
mechanic, you are not at his full mercy.
Note - This unit is not compatible with most diesel engines.
