DESCRIPTION AND OPERATION
COMPASS/TEMPERATURE MINI TRIP COMPUTER
SELF-DIAGNOSTIC TEST
The CMTC is capable of performing a diagnostic
self check on many of its internal functions. CMTC
diagnostics may be performed using a scan tool
(DRB) and the proper Body Diagnostic Procedures
manual or by the following procedure.
(1) With the ignition switch in the OFF position,
press both the US/M and STEP button.
(2) Turn ignition switch to the ON position.
The CMTC will perform internal checks while
lighting all segments of the vacuum florescent dis-
play. Upon completion of the internal check, the
CMTC will display.
²PASS
²FAIL
²CCd
If any segment of the CMTC fails to light replace
the module.
If FAIL is displayed, replace the module.
If CCd is displayed, check the CCD and Body Con-
trol Module (BCM) for proper operation, refer to the
appropriate diagnostic test procedures manual If the
CCD and the BCM are OK, replace the CMTC mod-
ule.
For additional diagnostic information on the CMTC
and for identifying CMTC problems, refer to the
proper Body Diagnostic Procedures manual.
COMPASS MINI-TRIP COMPUTER (CMTC)
The Compass Mini-Trip Computer (CMTC) system
is located in the overhead console. CMTC consists of
a electronic control module with a vacuum fluores-
cent display (VFD) and function switches. The CMTC
consists of a electronic module that displays compass,
trip computer, and temperature features. Actuating
the STEP switch will cause the CMTC to change
mode of operation when ignition is ON. Example:
²Compass/Temperature
²Trip odometer (ODO)
²Average miles per gallon (ECO)
²Instant miles per gallon (ECO)
²Distance to empty (DTE)
²Elapsed time (ET)
²Off
The CMTC module in the overhead console has
three buttons used to select various functions. The
CMTC selector buttons will not operate until the
ignition is in the RUN position (Fig. 1).
When the ignition switch is first turned to the
RUN position the CMTC display;
²Blanks momentarily
²All segments of the VFD will light for one sec-
ond
²Blanks momentarily
²Returns to the last mode setting selected before
the ignition was last switched OFF.

circuit information. If the resistance is greater than 1
ohm, repair the wire harness as necessary.
THROTTLE POSITION SENSOR
To perform a complete test of the this sensor and
its circuitry, refer to the DRB scan tool and appropri-
ate Powertrain Diagnostics Procedures manual. To
test the throttle position sensor only, refer to the fol-
lowing:
The Throttle Position Sensor (TPS) can be tested
with a digital voltmeter (DVM). The center terminal
of the sensor is the output terminal. One of the other
terminals is a 5 volt supply and the remaining ter-
minal is ground.
Connect the DVM between the center and sensor
ground terminal. Refer to Group 8W - Wiring Dia-
grams for correct pinout.
With the ignition switch in the ON position, check
the output voltage at the center terminal wire of the
connector. Check the output voltage at idle and at
Wide-Open-Throttle (WOT). At idle, TPS output volt-
age should be approximately 0.38 volts to 1.2 volts.
At wide open throttle, TPS output voltage should be
approximately 3.1 volts to 4.4 volts. The output volt-
age should gradually increase as the throttle plate
moves slowly from idle to WOT.
Check for spread terminals at the sensor and PCM
connections before replacing the TPS.
THROTTLE BODY MINIMUM AIR FLOW CHECK
PROCEDURE
(1) Warm engine in Park or Neutral until the cool-
ing fan has cycled on and off at least once.
(2) Ensure that all accessories are off.
(3) Shut off engine.
(4)3.0L Engine
(a) Hook-up the timing check device and tachom-
eter.(b) Disconnect the engine coolant temperature
sensor and set basic timing to 12É BTDC62É.
(c) Shut off engine. Reconnect coolant tempera-
ture sensor wire.
(5) Disconnect the PCV valve hose from the intake
manifold nipple (Fig. 101), (Fig. 102) or (Fig. 103).
(6) Cap the PCV valve nipple.
(7)3.3/3.8L Engines
(a) Install Air Metering Fitting 6457 (0.125 in.
orifice) to the intake manifold PCV nipple (Fig.
100).
(b) Disconnect the idle purge line from the throt-
tle body nipple.
(8)3.0/2.4L Engines
(a) Install Air Metering Fitting 6457 (0.125 in.
orifice) to the purge nipple on the throttle body.
(9)3.3/3.8L Engines
(a) Cap the 3/16 inch nipple.
(b) Connect the DRB scan tool to the data link
connector.
(10) Restart the engine. Allow engine to idle until
the cooling fan has cycled on and off at least one
180ÉF cycle.
(11) Using the DRB scan tool, access the Minimum
Airflow Idle Speed screen.
(12) The following will then occur:
²Idle air control motor will fully close.
²Idle spark advance will become fixed.
²DRB scan tool displays engine rpm.
(13) If idle rpm is within the range shown in the
Idle Specification chart, throttle body minimum air-
flow is set correctly.

off the engine and clean the throttle body as follows:
(a) Remove the throttle body from engine.
WARNING: CLEAN THROTTLE BODY IN A WELL
VENTILATED AREA. WEAR RUBBER OR BUTYL
GLOVES, DO NOT LET MOPAR PARTS CLEANER
COME IN CONTACT WITH EYES OR SKIN. AVOID
INGESTING THE CLEANER. WASH THOROUGHLY
AFTER USING CLEANER.
(b) While holding the throttle open, spray the
entire throttle body bore and the manifold side of
the throttle plate with Mopar Parts Cleaner.Only
use Mopar Parts Cleaner to clean the throttle
body.
(c) Using a soft scuff pad, clean the top and bot-
tom of throttle body bore and the edges and mani-
fold side of the throttle blade.The edges of the
throttle blade and portions of the throttle
bore that are closest to the throttle blade
when closed, must be free of deposits.
(d) Use compressed air to dry the throttle body.
(e) Inspect throttle body for foreign material.
(f) Install throttle body on manifold.
(g) Repeat steps 1 through 12. If the minimum
air flow is still not within specifications, the prob-
lem is not caused by the throttle body.
(15) Shut off engine.
(16) Remove Air Metering Fitting 6457 from the
intake manifold PCV nipple. Reinstall the PCV valve
hose.
(17) Uncap the throttle body idle purge nipple and
connect the idle purge line.
(18) Remove DRB scan tool.
