EC-278 < DTC/CIRCUIT DIAGNOSIS > [VK56VD] P0190, P0192, P0193 FRP SENSOR 6. CHECK FRP SENSOR SIGNAL CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect ECM harness connector. 3. Check the continuity between FRP sensor harness connector and ECM harness connector. 4. Also check harness for short to ground and to power. Is inspection result normal? YES >> GO TO 7. NO >> Repair or replace error-detected parts. 7. CHECK FRP SENSOR EC-278, "Component Inspection (Fuel Rail Pressure Sensor)" Is inspection result normal? YES >> Check intermittent incident. Refer to GI-40, "Intermittent Incident" . NO >> Repair or replace error-detected parts. Component Inspection (Fuel Rail Pressure Sensor) INFOID:0000000006288297 1. CHECK FRP SENSOR WITH CONSULT-III 1. Turn ignition switch OFF. 2. Reconnect harness connector disconnected. 3. Start the engine. 4. Select “DATA MONITOR” mode with CONSULT-III. 5. Check that the “FUEL PRES SEN V” indication. WITHOUT CONSULT-III 1. Turn ignition switch OFF. 2. Reconnect harness connector disconnected. 3. Start the engine. 4. Check FRP sensor signal voltage. Is the inspection result normal? YES >> INSPECTION END. NO >> Replace FRP sensor.
