DTC P0190 COMMON RAIL FUEL PRESSURE SENSOR
Diagnostic Procedure
EBS004RH
1. CHECK COMMON RAIL FUEL PRESSURE SENSOR POWER SUPPLY CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect common rail fuel pressure sensor harness connec-
tor.
3. Turn ignition switch “ON”.
4. Check voltage between common rail fuel pressure sensor termi-
nal 1 and ground with CONSULT-II or tester.
OK or NG
OK >> GO TO 2.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
2. CHECK COMMON RAIL FUEL PRESSURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Check harness continuity between common rail fuel pressure sensor terminal 3 and engine ground. Refer
to Wiring Diagram.
3. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING PART
Check harness for open or short between ECM and common rail fuel pressure sensor.
>> Repair open circuit or short to ground or short to power in harness or connectors.

Component InspectionEBS004RI
COMMON RAIL FUEL PRESSURE SENSOR
1. Reconnect harness connector disconnected.
2. Start engine and warm it up to normal operating temperature.
3. Check voltage between ECM terminals B13, B14 (Common rail
fuel pressure sensor signal) and ground under the following con-
ditions.
4. If the voltage is out of specification, disconnect common rail fuel
pressure sensor harness connector and connect it again. Then
repeat above check.
5. If NG, replace common rail.

DTC P0335 CRANKSHAFT POSISTION SENSOR (TDC)PFP:23731
DescriptionEBS004RQ
The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with 23 protrusions)
installed to the fly wheel. The datum signal output is detected 15°
signal and sent to the ECM. The sensor signal is used for fuel injec-
tion control and fuel injection timing control.
CONSULT-II Reference Value in Data Monitor ModeEBS004RR
Specification data are reference values.
ECM Terminals and Reference ValueEBS004RS
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.)

EBS004RT
DTC Confirmation ProcedureEBS004RU
Before performing the following procedure, confirm that battery voltage is more than 10V.
WITH CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode
with CONSULT-II.
2. Crank engine for at least 1 second.
3. Start engine and run it for at least 2 seconds at idle speed.
4. If DTC is detected, go to EC-1482, "
Diagnostic Procedure" .
