Explanation
signal. If more than two
ignition signals are not
recognized than there might
be a problem in feedback line.
Functional check against a
calculated value by
monitoring flow though air
mass meter to determine if
idle valve is mechanically
stuck open. Tested during
closed throttle.
Signal range is checked
against predefined diagnostic
limits. No vehicle speed is
observed after specific time
when compared to engine
speed and load equivalent to
moving vehicle.
Oxygen sensor signal range
is checked to determine if
electrical disconnection exist
on input line.
Oxygen sensor signal range
is checked to determine if
electrical disconnection exist
on input line.
CAN message between
DME/EGS was not received
within expected time.
Hardware test determines if
CAN bus is off line. Data
transmission is disturbed.
Checks amount of time
oxygen sensor stays in rich or
lean state. If it remains there
too long in either, fault will
set.
