3. ECM (CAN) signal to EPS
Speed (SPd) Diagnostic Mode
Display: vehicle speed signal.
DTC: P0500
Usage: verify speedometer sensor signal from the follow-
ing.
1. Speed sensor to ECM.
2. ECM (CAN) signal to gauge (speedometer/odome-
ter).
3. ECM (CAN) signal to EPS unit.
TPS (tPS) Diagnostic Mode
Display: % of TPS (0% closed, 95-100% WOT).
DTC: P0121, P0122, P0123
Usage: Verify TPS signal and adjust throttle cable.

MAP (bArO) Diagnostic Mode
Display: MAP in millibars (1013 millibar = 29.92 in.

mercury).
DTC: P0107, P0108
Usage: Verify barometric pressure signal correct.
Note: Local barometric pressure is given in in./
Hg (Inches of Mercury). 34 millibars are equal to 1
inch of mercury. Example: (Gauge reading in the
BARO mode = 974 millibars, thus 974/34 = 28.64
in./Hg). Second example: (Local barometer reading
is 29.87 in./Hg, therefore 29.87 X 34 = 1015 milli-
bars) The gauge should be reading very close to
1015.
Inlet Air Temperature (AIr)
Diagnostic Mode
EFI007
Display: Inlet air temperature in Fahrenheit or Celsius.
DTC: P0112, P0113, P0114
Usage: Verify correct output of IAT sensor.
NOTE: After engine has been running, IAT read-
ings will be higher than outside air temperature
due to engine and engine compartment heat as
well as intake manifold heating.
