P0079 B1 Exhaust Valve Control Solenoid Dera Low

P0079 B1 Exhaust Valve Control Solenoid Dera Low

Mapepala a OBD-II DTC

Mulingo wotsika wazizindikiro zamagetsi zamagetsi zamagetsi (Bank 1)

Kodi izi zikutanthauzanji?

Khodi iyi ndi generic OBD-II powertrain code, zomwe zikutanthauza kuti imagwira ntchito popanga ndi mitundu yonse yamagalimoto (1996 ndi atsopano), ngakhale njira zina zakukonzanso zitha kusiyanasiyana kutengera mtunduwo.

Pamagalimoto okhala ndi dongosolo losinthira ma valavu (VVT), gawo loyendetsa injini / powertrain control module (ECM / PCM) limayang'anira momwe camshaft imasinthira pakusintha kwamafuta amafuta ndi camshaft position control solenoid. The solenoid yowongolera imayang'aniridwa ndi chizindikiritso cha pulse wide modulated (PWM) kuchokera ku ECM / PCM. ECM / PCM imayang'anira chizindikirochi ndipo, ngati mphamvu yamagetsi ili pansipa, imayika DTC iyi ndikuwunikira Nyali ya Chizindikiro Chosagwira (MIL).

Bank 1 imatanthawuza mbali ya # 1 ya silinda ya injini - onetsetsani kuti mwayang'ana molingana ndi zomwe wopanga amapanga. The exhaust valve control solenoid nthawi zambiri imakhala pambali yotulutsa mpweya wambiri wa mutu wa silinda. Khodi iyi ndi yofanana ndi ma code P0078 ndi P0080. Khodi iyi imathanso kutsagana ndi P0027.

Zizindikiro

Zizindikiro zimaphatikizapo:

• Nyali Yazizindikiro Zosagwira (MIL) yaunikira
• Kuthamangira koyipa
• Kuchepetsa mafuta

Zotheka

Zomwe zingayambitse DTC P0079 zitha kuphatikiza:

• Chingwe cholumikizira chimafupikitsidwa pansi
• Magetsi amafupikira pansi
• ECM yolakwika

Njira zodziwira

Wiring Harness - Lumikizani zolumikizira ku PCM/ECM pogwiritsa ntchito chithunzi cha mawaya, pezani mawaya + ndi - ku solenoid. Solenoid ikhoza kuyendetsedwa kuchokera pansi kapena kuchokera kumbali ya mphamvu, malingana ndi ntchito. Onaninso zojambula zamawaya a fakitale kuti muwone momwe magetsi amayendera pozungulira. Pogwiritsa ntchito digito voltmeter (DVOM) yokhazikitsidwa ku ma volts, yang'anani voteji pa waya wa batri ya galimoto yabwino ndi waya woipa pa waya uliwonse kupita ku solenoid yolamulira. Kutengera kugwiritsa ntchito, ngati solenoid yakhazikika ku chassis, yang'anani waya wamagetsi ku solenoid yowongolera mu PCM/ECM wiring harness, payenera kukhala palibe magetsi. Ngati magetsi alipo, yang'anani pang'ono kuti mutsike mu waya ku control solenoid podula zolumikizira ndikubwerera ku solenoid.

Control Solenoid - Yang'anani pang'onopang'ono mpaka pansi kudzera pa solenoid yolamulira mwa kulumikiza chiwongolero chimodzi cha DVOM ku malo abwino odziwika ndi china ku siteshoni iliyonse pa solenoid yolamulira. Ngati kukana kuli kochepa, solenoid ikhoza kufupikitsidwa mkati.

PCM/ECM - Ngati mawaya onse ndi control solenoid ali bwino, padzakhala kofunikira kuyang'anira solenoid pamene injini ikuyenda poyang'ana mawaya ku PCM/ECM. Pogwiritsa ntchito chida chojambulira chapamwamba chomwe chimawerengera magwiridwe antchito a injini, yang'anani kuzungulira kwa ntchito komwe kumakhazikitsidwa ndi control solenoid. Zidzakhala zofunikira kulamulira solenoid pamene injini ikuyenda pa liwiro la injini zosiyanasiyana ndi katundu. Pogwiritsa ntchito oscilloscope kapena graphical multimeter yokhazikitsidwa kuti igwire ntchito, lumikizani waya wolakwika kumalo odziwika bwino komanso waya wabwino ku terminal ya waya iliyonse pa solenoid yomwe. Kuwerenga kwa ma multimeter kuyenera kufanana ndi ntchito yomwe yatchulidwa pa chida chojambulira. Ngati akutsutsana, polarity ikhoza kusinthidwa - gwirizanitsani waya wabwino kumbali ina ya waya ku solenoid ndikubwereza kuyesa kuti muwone. Ngati palibe chizindikiro chopezeka kuchokera ku PCM, PCM yokha ikhoza kukhala yolakwika.

Zokambirana zokhudzana ndi DTC

• 2011 ku Tucson P0079Ndili ndi Tucson 2011 2.4, nyengo yozizira mtawuni ya Florida, inde, mbewa inali kufunafuna malo ogona ndipo inapeza malo pakati pa chivindikiro chapamwamba ndi chivindikiro cha valavu kuti mugone usiku, chipinda chimakhala ndi mawaya a chakudya chamadzulo. m'mawa mwake kutha kwatha, ma cylinders atatu okha ndi omwe adayamba, ... 

Mukufuna thandizo lina ndi nambala yanu ya p0079?

Ngati mukufunabe thandizo ndi DTC P0079, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
