По этим ошибкам неисправностей может быть больше, чем можно представить... начиная с кислородных датчиков, форсунок и тд, заканчивая утечками в системе впуска и выпуска. Короче...

P0125(2) Excessive Time To Enter Closed Loop Fuel Control
(2) This DTC will set on first trip fault is detected.
DTC P0125: EXCESSIVE TIME TO ENTER CLOSED LOOP FUEL CONTROL
DTC Set Criteria
At least 30 seconds have passed since engine started. Engine coolant temperature is more than 178°F (81°C). Engine speed is 1800-3500 RPM. Volumetric efficiency is 16-62 percent. Code will set if system does not enter closed loop control within 30 seconds of engine entering air/fuel mixture ratio feedback zone. Monitor is run only once per drive cycle.
Probable Causes
Heated Oxygen Sensor (HO2S) failed.
Fuel injector failed.
Fuel pressure regulator failed.
Fuel pump failed.
Fuel filter clogged.
Air intake system leak.
Exhaust system leak.
Powertrain Control Module (PCM) failed.
Diagnostic Procedure
NOTE: For terminal identification, see appropriate illustration under TERMINAL IDENTIFICATION in SELF-DIAGNOSTICS - INTRODUCTION article. For circuit and wire color identification, see appropriate wiring diagram in WIRING DIAGRAMS article.
NOTE: Federal vehicles have one front HO2S located in exhaust pipe upstream of catalytic converter. California vehicles have 2 front HO2S, one located upstream of left bank front catalytic converter and the other located upstream of right bank front catalytic converter.
Check front Heated Oxygen Sensor(s) (HO2S). See SENSORS under ENGINE SENSORS & SWITCHES in SYSTEM & COMPONENT TESTING article. If problem exists, replace front HO2S, then go to step 7 . If problem does not exist, go to next step.
Check wiring between front HO2S(s) and PCM 26-pin connector C-90 and 28-pin connector C-91. Also check 4-pin front HO2S connector(s) and PCM connectors C-90 and C-91. If problem exists, repair appropriate connector or wire, then go to step 7 . If problem does not exist, go to next step.
Disconnect each fuel injector connector and check resistance between fuel injector terminals. Resistance should be 13-16 ohms at 68°F (20°C). If any fuel injector resistance is not as specified, replace fuel injector. If all fuel injector resistances are as specified, go to next step.
Check wiring between injectors and PCM. Also check fuel injector connector, intermediate connectors and PCM 35-pin connector C-89. If problem exists, repair as necessary, then go to step 7 . If problem does not exist, go to next step.
Perform fuel pressure test. See FUEL PRESSURE under FUEL SYSTEM in BASIC DIAGNOSTIC PROCEDURES article. If fuel pressure is not within specifications, repair as necessary. If fuel pressure is within specifications, go to next step.
Check for intake system vacuum leak. Check for exhaust leaks at HO2S fittings, exhaust manifold or front pipes. Check for fuel filter and/or fuel line clogging. Check fuel pump for poor fuel delivery. If problem exists, repair as necessary, then go to next step. If problem does not exist, replace PCM, then go to next step.
Using scan tool, clear DTCs. Test drive vehicle following OBD-II drive cycle other monitor pattern. See OBD-II DRIVE CYCLES under VERIFYING REPAIRS in SELF-DIAGNOSTICS - INTRODUCTION article. Check for DTCs. Confirm DTC does not reset. See VERIFYING REPAIRS in SELF-DIAGNOSTICS - INTRODUCTION article.
DTC P0170 & P0173: FUEL TRIM MALFUNCTION
NOTE: On Federal vehicles, DTC P0170 applies to fuel trim malfunction on either bank. On California vehicles, DTC P0170 applies to fuel trim malfunction on bank 1 (cylinders No. 1, 3, and 5). DTC P0173 applies to fuel trim malfunction on bank 2 (cylinders No. 2, 4 and 6).
DTC Set Criteria
Engine is in closed loop control. Intake air temperature is more than 14°F (-10°C). Barometric pressure is more than 11 psi (76 kPa). Volume Airflow (VAF) sensor output frequency is 100 Hz or more. On all vehicles, code will set if long-range fuel correction is less than -12.5 percent, or more than +12.5 percent, for 5 seconds. On Federal vehicles, code will set if short-range fuel correction is less than -12.1 percent, or is more than +12.1 percent on 3.0L engine, or more than +11.7 percent on 3.5L engine, for 5 seconds. On California vehicles, code will set if short-range fuel correction is less than -7.4 percent, or more than +7.4 percent, for 5 seconds.

NOTE: For terminal identification, see appropriate illustration under TERMINAL IDENTIFICATION in SELF-DIAGNOSTICS - INTRODUCTION article. For circuit and wire color identification, see appropriate wiring diagram in WIRING DIAGRAMS article.
1Using scan tool, check data list item No. 13 (intake air temperature). If temperature displayed on scan tool is equal to actual air temperature as measured with a thermometer, go to next step. If temperature displayed on scan tool is not equal to actual air temperature, check intake air temperature sensor circuit. See DTC P0110: INTAKE AIR TEMPERATURE (IAT) SENSOR CIRCUIT MALFUNCTION .
2Using scan tool, check data list item No. 21 (engine coolant temperature). If temperature displayed on scan tool is equal to actual engine coolant temperature as measured with a thermometer, go to next step.

... давление топлива не соответствует норме, использование неподходящего топлива, неисправность форсунок... Это из книжки.
, но больше похоже на какую-то неиспр. топливной системы.
Для начала проверить давление, может фильтр забит... Мне последний раз (забирая машину из сервиса) сказали, что давление немного снизили, и вот возникли похожие проблемы...
Конечно попробуйте поменять заправку. Если не поможет, то ковырять топливную систему... датчики и механику...

во блин братья Казахи до чего дошли севодня в сервисе сняли штекир с датчика каторый установлен возле воздушного фильтра ,машина стала равней работать,резко газ в пол никаких провалов ,стоит опять подключить датчик,газ в пол машина захлебывается,и начинает стрелять в выхлопную трубу.а ошибка p0125 это случайно ни этот датчик накрылся??????

Так без расходомера, бензин льёт по полной...... вот и нет провалов.boda писал(а):севодня в сервисе сняли штекир с датчика каторый установлен возле воздушного фильтра ,машина стала равней работать,резко газ в пол никаких провалов
Попробуйте расходомер с другой машины, если он врёт все настройки разъедутся
на днях решил почистить фарсунки ,проверить свечи и провода,заехал в сервис ,компьютер показал опять ошибки р0170 и р0173,когда сняли инжектор,то оказалось что нет прокладки на впускном коллекторе,заменил топливный фильтр,после этих поцедур ,автомобиль стал намного лучше работать,но небольшой провал иногда поевляется,лампочка ses пока не горит,сервисмены предлогают залить литров 10 ,98 бензола???? :-k
