Diagnostic Procedure
EBS013TG
1.
CHECK OVERALL FUNCTION
With CONSULT-II
1.
Turn ignition switch ON.
2.
Select “P/N POSI SW” in “DATA MONITOR” mode with CON-
SULT-II.
3.
Check “P/N POSI SW” signal under the following conditions.
Without CONSULT-II
1.
Turn ignition switch ON.
2.
Check voltage between ECM terminal 110 and ground under the
following conditions.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 2.
2.
CHECK PNP SWITCH GROUND CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch OFF.
2.
Disconnect park/neutral position (PNP) switch harness connec-
tor.
3.
Check harness continuity between PNP switch terminal 2 and
ground.
Refer to Wiring Diagram.
4.
Also check harness for short to power.
OK or NG
OK
>> GO TO 3.
NG
>> Repair open circuit or short to power in harness or con-
nectors.

Component Description
EBS013TH
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
EBS013TI
Specification data are reference values.
ECM Terminals and Reference Value
EBS013TJ
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.
