DESCRIPTION AND OPERATION
Fuel Tank And Lines
WARNING: Do not smoke, carry lighted tobacco or an open flame of any type when
working on or near any fuel- related component. Highly flammable mixtures are always present
and may be ignited, possibly resulting in personal injury.
The vehicle utilizes a returnless fuel system consisting of:
zthe fuel tank.
z a fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped
into the fuel tank.
z a 1/8 turn fuel tank filler cap.
z a fuel filter providing filtration to protect the fuel injectors.
z a single fuel line accommodating the returnless fuel system.
z a fuel injection supply manifold which contains a differential pressure sensor and a fuel
temperature sensor.
z a fuel pump and sender assembly which provides pressurized fuel to the engine and contains:
„an inlet filter.
„ a check valve which maintains system pressure after the pump is shut off.
„ a pressure relief valve for overpressure protection in the event of restricted flow.
The fuel pump is controlled by an electronic fuel pump driver module which is enabled by the
powertrain control module (PCM). Electrical power to the fuel pump is provided through the inertia fuel
shutoff (IFS) switch, which is located in the luggage compartment. SECTION 310-

REMOVAL AND INSTALLATION
Fuel Filter
Removal
WARNING: Fuel supply lines on all vehicles equipped with fuel injected engines will
remain pressurized for long periods of time after engine shutdown. Fuel system pressure must
be relieved prior to fuel system service to prevent possible personal injury or a fire hazard.
1. Disconnect the battery. For additional information, refer to Section 414 - 01 .
2. Relieve the fuel system pressure. For additional information, refer to Section 310 - 00 .
3. Raise the vehicle. For additional information, refer to Section 100 - 02 .
4. Disconnect the filter push connect fittings. For additional information, refer to Section 310 - 00 .
5. Unsnap the filter from the bracket and remove.
Installation 1. To install, reverse the removal procedure.

Odometer
Display Description
GAGE Activates gauge sweep of all gauges, then displays present gauge values. Also
carries out the checksum tests on ROM and EE. All segments
illuminated Illuminates all odometer segments.
bulb Illuminates all micro-controlled indicators and LEDs. Install a new indicator or LED as
necessary. r Returns to normal operation of all micro-
controlled indicators and LEDs and displays
hexadecimal value for ROM level (used when requesting assistance from the hotline). EE Displays hexadecimal value for EE level (used when requesting assistance from the
hotline). dt Displays hexadecimal coding of final manufacturing test date (used when requesting
assistance from the hotline). dtc Displays continuous DTCs in hexadecimal format. Pressing the SELECT/RESET
button will display any DTCs stored before proceeding to the next step. enG Displays the English speed in mph. Speedometer will indicate present speed within
tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0. m Displays the metric speed data (km/h). Speedometer will indicate present speed
within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0. tAc Displays the tachometer data received from the PCM via the SCP network within
tolerances. Tachometer will indicate present rpm. Display will show 0 if input is not received, if input received is invalid for one second or more, or if engine rpm is 0. FUEL Displays the code (0-255) for the fuel sender input to the instrument cluster. The fuel
gauge will display a filtered fuel level value. This filter will keep the pointer from moving suddenly or erratically.
z255 = open send +/- 0
z 232 = full stop +/- 0
z 215 = full mark +/- 10
z 178 = 3/4 mark +/- 8
z 138 = 1/2 mark +/- 7
z 93 = 1/4 mark +/- 5
z 41 = E mark +/- 4
z 54=LOW FUEL (0- 59)
z 0-18=short (0- 20 max) OIL Displays the code (0-
250) for the oil pressure switch input to the instrument cluster.
Oil pressure gauge will indicate present oil pressure. Normal oil pressure (greater
than 6 psi) will display a value between 000 and 176. A low oil pressure or an
inoperative engine oil pressure switch (less than 6 psi) will display a value greater
than 176. dEGC Display of engine temperature in degrees C input from cylinder head temperature
sensor.
z 49 C = "C" mark
z 60 C = normal band start
z 120 C = normal band end
z -40 C = no SCP message for 5 seconds bAtt Displays the code (0-255) for the battery voltage input to the instrument cluster.
Battery voltage gauge will indicate present battery voltage. Klj . 6 ba
