function Signal type and
range Explanation
signal. If more than two
ignition signals are not
recognized than there might
be a problem in feedback line.
211 P1510 Idle control valve
stuck DME internal
values logical 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.
214 P0500 Vehicle speed
sensor Input digital
frequency (0-12V) 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.
215 P0136 Oxygen sensor
post-cat (Bank 1),
disconnection Input analog
(0-5V) Oxygen sensor signal range
is checked to determine if
electrical disconnection exist
on input line.
216 P0136 Oxygen sensor
post-cat (Bank 2),
disconnection Input analog
(0-5V) Oxygen sensor signal range
is checked to determine if
electrical disconnection exist
on input line.
217 P0505 CAN time out
(EGS1) Input digital binary
information(0-12V) CAN message between
DME/EGS was not received
within expected time.
219 CAN-chip, bus off Input digital binary
information (0-12V) Hardware test determines if
CAN bus is off line. Data
transmission is disturbed.
220 P1184 Oxygen sensor
post-cat (Bank 1)
slow response time Input analog (high
is lean) (0-5V) Checks amount of time
oxygen sensor stays in rich or
lean state. If it remains there
too long in either, fault will
set.
221 P1185 Oxygen sensor
post-cat (Bank 2)
slow response time Input analog (high
is lean) (0-5V) Checks amount of time
oxygen sensor stays in rich or
lean state. If it remains there
too long in either fault will set.
