Component DescriptionEBS011G9
The power steering pressure switch is attached to the power steer-
ing high-pressure tube and detects a power steering load.
When a power steering load is detected, it signals the ECM. The
ECM adjusts the fuel injector pulse width to increase the idle speed
and adjust for the increased load.
CONSULT-II Reference Value in Data Monitor ModeEBS011GA
Specification data are reference values.
ECM Terminals and Reference ValueEBS011GB
Specification data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

FUEL TRANSPORT PUMP
FUEL TRANSPORT PUMPPFP:17020
DescriptionEBS011PD
SYSTEM DESCRIPTION
Fuel supply entrance of fuel tank is at the left side of fuel tank. The duel at the right side of the fuel tank is sent
to the left side of the fuel tank by fuel transport pump.
When the ECM receives engine revolution signal from the crankshaft position sensor, it knows that the engine
is rotating, and causes the pump operate. If the remainder of the fuel at the right side of the fuel tank
decreases, fuel level switch sends a signal to the ECM. When the ECM receives a signal from the fuel level
switch, the ECM stops the operation of the pump.
The ECM does not directly drive the fuel transport pump. It controls the ON/OFF fuel transport pump relay,
which in turn controls the fuel transport pump.
COMPONENT DESCRIPTION
Fuel Transport Pump
Fuel transport pump sends the fuel from right side of fuel tank to left
side.
Fuel Level Switch
Fuel level switch is assembled in sub fuel level sensor unit. When the remainder of the fuel at the right side of
the fuel tank is less than specified value, the switch is turned OFF.
