FUEL PUMP
FUEL PUMP
DescriptionINFOID:0000000006342236
SYSTEM DESCRIPTION
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine
start ability. If the ECM receives a engine speed signal
from the crankshaft position sensor (POS) and cam-
shaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the
engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump
operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel
pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump.
COMPONENT DESCRIPTION
A turbine type design fuel pump is used in the fuel tank.
• Fuel level sensor unit and fuel pump (1)
• Fuel pressure regulator (2)
• Fuel level sensor (3)

BALANCING WHEELS (ADHESIVE WEIGHT TYPE)
Preparation Before Adjustment
Remove inner and outer balance weights from the r oad wheel using releasing agent, remove double-faced
adhesive tape from the road wheel.
CAUTION:
• Be careful not scratch the road wheel during removal.
• After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
Wheel Balance Adjustment
• If a balancer machine has an adhesive weight mode setting, select the adhesive weight mode setting and skip Step 2. below. If a balancer machine only has the clip-on (rim flange) weight mode setting, follow Step 2.
to calculate the correct size adhesive weight.
1. Set road wheel on balancer machine using the cent er hole as a guide. Start the balancer machine.
2. For tire balance machines that only have a clip-on (ri m flange) weight mode setting, follow this step to cal-
culate the correct size adhesive weight to use. When inner and outer imbalance values are shown on the
balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that
should be used. Select the outer balance weight with a value closest to the calculated value above and
install in to the designated outer position of, or at the designated angle in relation to the road wheel.

O-Ring Specifications*
* : Always check with the parts department for the latest parts information.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
• When the compressor is removed, store it in the sam e position as it is when installed on the vehicle.
Doing so will cause oil to en ter the low-pressure chamber.
• When connecting tubes, always use a to rque wrench and a back-up wrench.
• After disconnecting tubes, immediately plug all op enings to prevent entry of dirt and moisture.
• When installing an air conditione r in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for con-
nection.
• Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
• Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
• Always replace used O-rings.
• When connecting tube, apply the speci fied A/C oil to circle of the O-rings. Be careful not to apply oil
to threaded portion. Refer to MTC-96, "
Oil".
• O-ring must be closely attached to dented portion of tube.
• When replacing the O-ring, be careful not to damage O-ring and tube.
• Connect tube until you hear it cl ick, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.
• After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.

SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or aut omatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. If the scale controls refriger-
ant flow electronically, the hose fitting must be 1/2 ″-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not re commended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accura cy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precaution for Leak Detection DyeINFOID:0000000005930832
• The A/C system contains a fluorescent leak detection dy e used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
• Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
• The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to pin-
point refrigerant leaks.
• For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.
• A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should
only be repaired after confirming the leak with an electronic refrigerant leak detector.
• Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis dur-
ing a future service.

PREPARATION
HFC-134a (R-134a) Service Tool and EquipmentINFOID:0000000005930833
Never mix HFC-134a refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed
use of the refrigerants/oil.
Adapters that convert one size fitting to another must never be used refrigerant/oil contamination will occur
and compressor failure will result.

OIL
1. Before connecting recovery/recycling equipment to vehicle, check recovery/recycling equipment gauges.
No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.
2. Discharge refrigerant into the refrigerant recove ry/recycling equipment. Measure oil discharged into the
recovery/recycling equipment.
3. Drain the oil from the old (removed) compressor into a graduated container and recover the amount of oil drained.
4. Drain the oil from the new compressor into a separate, clean container.
5. Measure an amount of new oil installed equal to amount drained from old compressor. Add this oil to new compressor through the suction port opening.
6. Measure an amount of new oil equal to the amount recovered during discharging. Add this oil to new com- pressor through the suction port opening.
7. If the liquid tank also needs to be replaced, add another 5 m (0.2 US fl oz, 0.2 Imp fl oz.) of oil at this
time.
Add this 5 m (0.2 US fl oz, 0.2 Imp fl oz.) of oil only when replacing the compressor.
