P1220 NISSAN — Модуль управления топливным насосом
Неправильный сигнал напряжения от модуля управления топливным насосом (FPCM), который подается в точку между топливным насосом и понижающим резистором, обнаруживается модулем управления двигателем (ECM).

P1220 Nissan Описание
Эта система контролирует работу топливного насоса. Объем подачи топлива из топливного насоса изменяется между двумя расходами посредством модуля управления топливным насосом (FPCM) операция. FPCM определяет напряжение, подаваемое на топливный насос (и, следовательно, поток топлива) в соответствии со следующими условиями. FPCM регулирует напряжение, подаваемое на топливный насос, чтобы контролировать количество потока топлива. Когда FPCM увеличивается напряжение, подаваемое на топливный насос, увеличивается расход топлива. Когда FPCM уменьшается напряжение, расход топлива уменьшается.

DTC CONFIRMATION PROCEDURE
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
� Before performing the following procedure, confirm that battery voltage is between 12 — 15 V at idle.
� Before performing the following procedure, check that the engine coolant temperature is −10�C (14�F) or more.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and let it idle for at least 5 seconds.
If engine does not start, crank engine for at least 5 seconds.
Is DTC detected? YES >> Proceed to EC-323, «Diagnosis Procedure».
Diagnosis Procedure
1.CHECK FPCM POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect FPCM harness connector.
3. Turn ignition switch ON.
4. Check the voltage between FPCM harness connector and ground.
Is the inspection result normal? YES >> GO TO 2.
2.CHECK FPCM POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector.
3. Check the continuity between FPCM harness connector and IPDM E/R harness connector.
4. Also check harness for short to ground.
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK FPCM GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Check the continuity between FPCM harness connector and ground.
3. Also check harness for short to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK FPCM INPUT AND OUTPUT CIRCUITS
1. Disconnect ECM harness connector.
2. Check the continuity between FPCM harness connector and ECM harness connector
3. Also check harness for short to ground and to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK FUEL PUMP CONTROL CIRCUIT
1. Disconnect fuel level sensor unit (fuel pump) harness connector.
2. Check the continuity between FPCM harness connector and fuel level sensor unit (fuel pump) harness connector.
3. Also check harness for short to ground and to power.
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
Check the FPCM. Refer to EC-325, «Component Inspection (FPCM)».
Is the inspection result normal? YES >> Check intermittent incident .Refer to GI-42, «Intermittent Incident».
NO >> Replace FPCM. Refer to EC-448, «Removal and Installation».
Component Inspection (FPCM)
1.CHECK FUEL PUMP CONTROL MODULE (FPCM)
Check the voltage between FPCM terminals as per the following conditions.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace FPCM. Refer to EC-448, «Removal and Installation».
