What is the difference between
a Code Reader and a Code Scanner? Readers and Scanners both display vehicle
computer fault codes with descriptions. Scanners have the additional function of
providing real-time component voltage and current outputs. Some examples of
these components are: 02 Sensors, Fuel Injectors, Throttle Position Sensors, and
Transmission Sensors.
What is the difference between
OBD I & OBD II (On-Board Diagnostic I & II)? OBD I covers: Ford and
Chrysler vehicles 1983-1995, Jeep vehicles 1991-1995, and GM vehicles 1982-1995.
Import vehicles used other diagnostic standards prior to 1996. OBD II covers
all vehicles 1996-present.
