The
following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
The
engine and the automatic transmission (transmission control is
only for automatics, engine is still computer controlled no matter
the transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM or ECM,ECU), which is very rarely the
problem. Other basic checks must be done as well such as mechanical
problems with the engine as well as engine state of tune and mileage
on the engine. The transmission can have mechanical issues as well
such as no gear engagement at all or a failed pump or other pressure
related problems. Also engine mechanical problems can and do cause
many drive-ability related problem such as rough idle and other
symptoms.
