TPS (tPS) Diagnostic Mode
EFI028
Display: % of TPS (0% closed, 95-100% WOT).
DTC: P0121, P0122, P0123
Usage: Verify TPS signal and adjust throttle cable.
MAP (bArO) Diagnostic Mode
EFI027
Display: MAP in millibars (1013 millibars = 29.92 in.
Hg).
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 millibars). The
gauge should be reading very close to 1015.
IAT (AIr) Diagnostic Mode
EFI026
Display: Inlet air temperature in Fahrenheit or Celsius.
112
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.
Battery (bAtt) Diagnostic Mode
EFI025
Display: System DC voltage.
DTC: P0562, P0563, P2531, P2532
Usage: Verify system voltage under following condi-
tions.
1. Battery voltage with engine and accessories off
(>12.2 VDC for fully charged).
2. Battery voltage with engine running (charging = 13.8
VDC or greater).
3. Battery voltage with electrical accessories operating,
engine idling (13.5 VDC or greater).
4. Battery voltage starter cranking (10.5-11.5 VDC).
DIAGNOSTIC TROUBLE CODES (DTC)
If an EFI or related chassis component fails or an
out-of-tolerance signal is detected by the ECM, a diag-
nostic trouble code (DTC) will be generated in the ECM
and displayed on the LCD. The DTC will continue to
flash until the malfunction is corrected and the code
cleared.
Code List

NOTE: Each of the following numerical codes will
have a one-letter prefix of C, P, or U. A "C" prefix
denotes a chassis malfunction, a "P" prefix denotes a
power train malfunction, and a "U" prefix denotes a
loss of communication with the gauge.

NOTE: Normal malfunction codes are cleared from
the LCD when the component is replaced or the mal-
function is corrected; however, intermittent codes
must be cleared as noted in the code chart.
