FUEL PUMP CIRCUITPFP:17042
DescriptionEBS00B9W
SYSTEM DESCRIPTION
The ECM activates the fuel pump for several seconds after the ignition switch is turned on to improve engine
startability. If the ECM receives a 180°signal from the camshaft position sensor (PHASE), it knows that the
engine is rotating, and causes the pump to operate. If the 180°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.
CONSULT-II Reference Value in Data Monitor ModeEBS00B9X
Specification data are reference values.
ECM Terminals and Reference ValueEBS00B9Y
Specification data are reference values and are measured between each terminal and body 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.
