DTC P0500 VSSPFP:32702
Component DescriptionEBS00NGR
The vehicle speed signal is sent to the combination meter from the 4WD/ABS control unit. The combination
meter then sends a signal to the ECM.
ECM Terminals and Reference ValueEBS00NGS
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II
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.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
On Board Diagnosis LogicEBS00NGT
DTC Confirmation ProcedureEBS00NGU
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
This procedure may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
WITH CONSULT-II
1. Start engine.
2. Read “VHCL SPEED SE” in “DATA MONITOR” mode with CON-
SULT-II. The vehicle speed on CONSULT-II should exceed 10
km/h (6 MPH) when rotating wheels with suitable gear position.
If NG, go to EC-567, "
Diagnostic Procedure" .
If OK, go to following step.
3. Select “DATA MONITOR” mode with CONSULT-II.
4. Warm engine up to normal operating temperature.
5. Maintain the following conditions for at least 60 consecutive sec-
onds.

Overall Function CheckEBS00NGV
Use this procedure to check the overall function of the vehicle speed sensor circuit. During this check, a 1st
trip DTC might not be confirmed.
WITHOUT CONSULT-II
1. Lift up the vehicle.
2. Start engine.
3. Read vehicle speed with combination meter.
The vehicle speed indication should be able to exceed 10 km/h (6 MPH) when rotating wheels with suit-
able gear position.
4. If NG, go to EC-567, "

DTC P0550 PSP SENSOR
DTC P0550 PSP SENSOR
PFP:49763
Component DescriptionEBS00NGY
Power steering pressure (PSP) sensor is installed to the power
steering high-pressure tube and detects a power steering load. This
sensor is a potentiometer which transforms the power steering load
into output voltage, and emits the voltage signal to the ECM. The
ECM controls the electric throttle control actuator and adjusts the
throttle valve opening angle to increase the engine speed and
adjusts the idle speed for the increased load.
CONSULT-II Reference Value in Data Monitor ModeEBS00NGZ
Specification data are reference values.
ECM Terminals and Reference ValueEBS00NH0
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.
On Board Diagnosis LogicEBS00NH1
The MI will not light up for this diagnosis.
DTC Confirmation ProcedureEBS00NH2
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch “ON”.
