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.
