EC-1186
[YD (WITH EURO-OBD)]
PSP SWITCH
PSP SWITCH PFP:49761
Component Description EBS011G9
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 Mode EBS011GA
Specification data are reference values.
ECM Terminals and Reference Value EBS011GB
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.
