DescriptionEBS01265
When the gear position is in Neutral, park/neutral position is ON. ECM detects the position because the conti-
nuity of the line (the “ON” signal) exists.
CONSULT-II Reference Value in Data Monitor ModeEBS01266
Specification data are reference values.
ECM Terminals and Reference ValueEBS01267
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.

Component DescriptionEBS0126A
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.

CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
