Я так понял,что о дизеле речь?Тоже проблемма с правильной трактовкой ошибки Р1183 -Киа Соренто 2004г. 2.5л.

COMPONENT LOCATION



P1188 Fuel Pressure Monitoring-Leakage



GENERAL DESCRIPTION



As inputted rail pressure sensor signal, ECM of Commom rail diesel engine controls fuel metering unit(FPRV-intergrated with high press. pump) and rail pressure control valve(RPRV-integrated with common rail) in order to maintain optimum rail pressure according to current engine rpm and load. However when the problem that leads rail pressure to out of target value intended by ECM occurs due to mechanical or electronical reason, ECM limits engine performance and sets DTC by limiting fuel (stops injector operation) in order to prevent engine from being controlled abnormally. "rail pressure monitoring error" is the DTC which diagnoses 1) supplying state of low pressure fuel and 2) mechanical operating conditions of high pressure pump and 3). RPRV indirectly based on RPS output voltage and RPS duty. Thus, repair relavant to this DTC requires mechanics the total understand of fuel system.

DTC DESCRIPTION



P1188 is set when rail pressure is lower than target rail pressure by more than 250bar for more than 0.8 sec. in condition that rail press. is controlled by rail pressure regulator valve(RPRV) or rail pressure is below the lower limit value(200bar). This code is due to 1)fuel less than target value supplied to common rail or 2)excessive return of fuel supplied to common rail or 3)short to low voltage line in rail press. sensor.

DTC DETECTING CONDITION

Item Detecting Condition Possible Cause

DTC Strategy • Voltage monitoring

(maximum negative rail pressure deviation with closed pressure control valve exceeded)

• fuel pressure regulator valve (close stuck)

• rail pressure regulator valve (open stuck)

• Rail pressure sensor(Output fixed at low voltage line)



Enable Conditions • Engine running



Threshold Value • Rail pressure is below target rail pressure by more than 250bar at rail pressure regulator valve(RPRV) operating condition.

• Rail pressure is below minimum limiting value(200bar) at rail pressure regulator valve(RPRV) operating condition.



Diagnostic Time • 0.8 sec.



Fail Safe Fuel cut NO

EGR Off NO

Fuel Limit YES

Check Lamp YES



MONITOR SCANTOOL DATA

1. Monitoring rail pressure data

(1)

Connect Scantool to Data Link Connector (DLC).

(2)

Warm engine up to normal operating temperature.

(3)

Turn "OFF" electrical devices and A/C.

(4)

Monitor "FUEL PRESSURE MEASURED", "FUEL PRESS. S/POINT", "RAIL PRESS. REGULATOR1", "INJ. PUMP REGULATOR" parameter on the Scantool.



--------------------------------------------------------------------------------



Specification :

FUEL PRESSURE MEASURED : similar to "FUEL PRESSURE-TARGET"

FUEL PRESS. S/POINT : 28.5 ± 5 Mpa

RAIL PRESS. REGULATOR1 : 17 ± 5%

INJ. PUMP REGULATOR : 35 ± 5%



--------------------------------------------------------------------------------









Check if "FUEL PRESSURE MEASURED"data is similar to "FUEL PRESS. S/POINT". Not only former two data but also "RAIL PRESS. REGULATOR1" and "INJ. PUMP REGULATOR"should be monitored carefully. Although "FUEL PRESSURE MEASURED" is similar to "FUEL PRESS. S/POINT", if "RAIL PRESS. REGULATOR1" and "INJ. PUMP REGULATOR" is out of specification, it means wear, leakage, stuck of fuel system.



2. Monitoring rail pressure data at acceleration(loading condition).

(1)

Connect Scantool to Data Link Connector (DLC).

(2)

Warm engine up to normal operating temperature.

(3)

Turn "OFF" electrical devices and A/C.

(4)

Monitor "FUEL PRESSURE MEASURED", "INJ. PUMP REGULATOR","RAIL PRESS. REGULATOR1" parameter on the Scantool.

Specification :

Idle(without load) Accelerating(stall test) Diagnosis

FUEL PRESSURE MEASURED 28 ± 5 Mpa above 75 Mpa press. increases

INJ. PUMP REGULATOR 35 ± 5% 38 ± 5% duty increases

RAIL PRESS. REGULATOR1 17 ± 5% 45 ± 5% duty increases















The waveform of fuel pressure regulator valve installed at high pressure pump(fuel detecting MPROP) shows 35 ± 5% duty at idle, duty rises to approx. 40% at acceleration to raise rail pressure.

→ Fuel amonut delivered from injection pump to rail is increases if the duty of "Fuel pressure regulator" increases



The waveform of rail pressure regulator valve installed at common rail shows 17 ± 5% duty at idle, duty rises to approx. 45% at acceleration to raise rail pressure.

→ If the current increases, pressure in common rail will increase. because fuel return amount delivered to commom rail will decrease.



VERIFICATION OF VEHICLE REPAIR



After a repair, it is essential to verify that the fault is corrected.

1. After connecting Scantool select "DIAGNOSTIC TROUBLE CODES(DTCs)" mode.

2. Clear recorded DTC using Scantool.

3. Drive the vehicle within DTC "Enable conditions" in "General information".

4. After selecting "DIAGNOSTIC TROUBLE CODES(DTCs)" mode and check if DTC is recorded again.

5. Are any DTCs recorded ?





▶ Go to the DTC guide of recorded NO. in Scantool.





▶ System operates within specification.

Это по этому коду.Поздновато наверное,но на будущее может кому згодится.

Дык двигло и интересует, остальное-то более менее как на бензиновом...
