sensor JAGUAR XFR 2010 1.G Workshop Manual

15 Fuel pump module The fuel tank is a saddle type tank, blow moulded from HDPE (high density polyethylene). The tank is located forward of the
rear suspension and is mounted using two metal straps. The tank is a sealed unit with the only internal access being through
the fuel pump module aperture on the top of the tank.

The fuel pump module flange has a six pin external connector which provides the electrical connections for the fuel pump and
both fuel level sensors. A quick release connector provides for the connection of the fuel feed pipe.

The flange is fitted with a locking ring and seal. The seal locates in a groove on the tank. The locking ring locates and clamps
on the encapsulated ring that is moulded into the fuel tank. The flange has a tag which locates in the top of the tank to
ensure correct orientation.

A carrier within the tank provides for the mounting of the passive side jet pump tube, vent valve, ROV and liquid vapor
separator (LVS), level sensors and passive side drain.

FUEL PUMP MODULE

1 Fuel supply connection 2 Electrical connector 3 Flange locking ring and seal 4 Sucking jet connector 5 Fuel pump module 6 Fuel pick up filter 7 Level sensor float 8 RH level sensor 9 Fuel filter 10 Pressure relief valve 11 Pump supply to flange connection 12 The fuel pump is a variable speed rotary vane type. The pump is energized by the fuel pump relay which is located in the RJB and the FPDM which is located under the RH floor pan above the rear suspension stabilizer bar. The relay and FPDM are controlled by the ECM.
A fine mesh filter is located in the lower section of the pump module. This provides filtration to the fuel as it is drawn into the
module. There is a winged filter on the fuel pump that gives additional protection and a life time fuel filter integrated into the
flange which eliminates the need for an additional filter further downstream in the fuel system.
The RH fuel level sensor is mounted into the pump module housing.
FUEL PUMP DRIVER MODULE (FPDM)



The FPDM is located on a bracket which is integral with the charcoal canister. The module is attached to one end of the canister with a bracket.

The fuel pump operation is regulated by a FPDM which is controlled by the ECM. The FPDM regulates the flow and pressure supplied by controlling the operation of the fuel pump using a PWM (pulse width modulation) output.

The FPDM is powered by a supply from the fuel pump relay in the RJB. The fuel pump relay is energized on opening the driver's door, pressing the start button only or pressing the start button and the footbrake (which initiates engine cranking). The FPDM supplies power to the fuel pump, and adjusts the power to control the speed of the fuel pump and thus the pressure and flow
in the fuel delivery line.

A PWM signal from the ECM tells the FPDM the required speed for the fuel pump. The on time of the PWM signal represents half the fuel pump speed, e.g. if the PWM signal has an on time of 50%, the FPDM drives the pump at 100%.
The FPDM will only energize the fuel pump if it receives a valid PWM signal, with an on time of between 4% and 50%. To switch the fuel pump off, the ECM transmits a PWM signal with an on time of 75%.
The output pressure from the fuel pump will change with changes of engine demand and fuel temperature. The ECM monitors the input from the fuel rail LP sensor and adjusts the speed of the fuel pump as necessary to maintain a nominal output
pressure of 450 kPa (4.5 bar; 65.3 lbf/in.2
), except during engine start-up. At engine start-up the target pressure for the fuel
delivery line is 630 kPa (6.3 bar; 91.4 lbf/in.2
).
If the SRS (supplemental restraint system) outputs a crash signal on the high speed CAN (controller area network), the ECM de-energizes the fuel pump relay to prevent any further fuel being pumped to the engine.

If the ECM does not detect pressure in the fuel delivery line, it stops, or refuses to start the engine and stores the appropriate DTC (diagnostic trouble code).
The ECM receives a monitoring signal from the FPDM. Any DTC's produced by the FPDM are stored by the ECM.
DTC's can be retrieved from the ECM using an approved Jaguar diagnostic system. The FPDM itself cannot be interrogated by the approved Jaguar diagnostic system.

1 Fuel level sensor 2 Fuel level sensor float arm 3 Fuel level sensor float Two fuel level sensors are installed in either side of the saddle tank. One is mounted on the fuel pump module, the other is
mounted on the carrier in the LH side of the fuel tank. The sensors are a float operated MAPPS (magnetic passive position sensor) which provide a variable resistance to ground for the output from the fuel gauge. The sensor is sealed from the fuel
preventing contamination of the contacts, increasing reliability. The fuel level sensors are connected to the external electrical
connector on the flange via the connector on the underside of the fuel pump module flange.

The sensor comprises a series of 51 film resistors mounted in an arc on a ceramic surface. The resistors are wired in series
with individual contacts. A soft magnetic foil with 51 flexible contacts is mounted a small distance above the film resistors. A
magnet, located below the ceramic surface, is attached to the sender unit float arm. As the float arm moves, the magnet
follows the same arc as the film resistors. The magnet pulls the flexible contacts onto the opposite film resistor contacts
forming an electrical circuit.

For a detailed description of the acceleration controls, refer to the relevant Description and Operation sections in the workshop
manual. REFER to: Acceleration Control (310-02, Description and Operation).

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage and system integrity.

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:


If the module or a component is suspect and the vehicle remains under the Manufacturers warranty, refer to the Warranty
Policy and Procedure manual (section B1.2), or determine if any prior approval programme is in operation, prior to the
installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer-approved diagnostic system).


When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
