Mene ne wannan yake nufi?

Wannan Lambar Matsala Mai Rarraba / Injin Bincike na Injin Bincike (DTC) galibi ya shafi duk injunan diesel na OBD-II, amma ya fi yawa a wasu manyan motocin Chevy, Dodge, Ford da GMC.

Kodayake gabaɗaya, madaidaitan matakan gyara na iya bambanta dangane da shekarar ƙirar, ƙirar, ƙirar, da tsarin watsawa.

Densel Intake Air Flow Pens Sensor (DIAFPS) galibi ana makale shi a jikin maƙura da aka ɗora a kan kayan abinci mai yawa ko a cikin bututu a cikin kwararar iska. Na'urar firikwensin DIAFPS tana jujjuya ƙimar iska zuwa siginar lantarki don tsarin sarrafa wutar lantarki (PCM).

PCM yana karɓar wannan siginar ƙarfin lantarki don tantance yawan tsabtataccen iskar da ke shiga injin tare da nawa ke shiga tsarin ɓarna ta hanyar tsarin EGR ko EGR. Lokacin da aka kunna EGR, PCM ya kamata ya lura da canji a cikin kwararar iska. Idan ba haka ba, akwai yuwuwar wani abu mara kyau tare da tsarin EGR, ko kuma akwai wani abu da ba daidai ba tare da DIAFPS, wanda kuma aka sani da firikwensin iska mai yawa. An saita wannan lambar idan wannan shigarwar ba ta dace da yanayin aikin injin na yau da kullun da aka adana a cikin ƙwaƙwalwar PCM ba, har na daƙiƙa ɗaya, kamar yadda waɗannan DTC ke nunawa. Hakanan yana kallon siginar ƙarfin lantarki daga DIAFPS don sanin ko daidai ne lokacin da aka kunna maɓallin farko.

Menene wasu matakan magance matsalar P02FA?

Kyakkyawan farawa shine koyaushe bincika Sabis ɗin Sabis na Fasaha (TSB) don abin hawan ku. Matsalar ku na iya zama sanannen batun tare da sanannen fitowar masana'anta kuma zai iya ceton ku lokaci da kuɗi yayin warware matsalar.

Sannan nemo firikwensin DIAFPS akan abin hawa. Wannan abin firikwensin yawanci ana makale shi ne ga jikin maƙura da aka ɗora a kan ninki mai yawa ko a cikin bututu a cikin rafin iska. Da zarar an same shi, a gani a duba mai haɗawa da wayoyi. Nemo karce, goge -goge, wayoyi da aka fallasa, alamomin ƙonawa, ko narkakken filastik.

Idan kuna buƙatar tsabtace tashoshi, yi amfani da mai tsabtace lambar lantarki da goga na goga. Bada damar bushewa da shafa man shafawa na lantarki inda tashoshin tashoshi ke taɓawa.

Idan kuna da kayan aikin dubawa, share DTCs daga ƙwaƙwalwar ajiya kuma duba ko lambar P02FA ta dawo. Idan ba haka ba, matsalar ta fi zama batun haɗi.

Idan lambar P02FA ta dawo, za mu buƙaci gwada firikwensin DIAFPS da da'irori masu alaƙa. Tare da maɓallin KASHE, cire haɗin haɗin lantarki a firikwensin DIAFPS. Haɗa jagorar baƙar fata daga DVM zuwa tashar ƙasa akan mahaɗin harness na firikwensin DIAFPS. Haɗa jan gubar daga DVM zuwa tashar siginar akan mahaɗin kayan ɗamarar firikwensin DIAFPS. Kunna injin, kashe shi. Duba ƙayyadaddun ƙira; voltmeter ya kamata ya karanta 5 volts. In ba haka ba, gyara siginar ko waya ta ƙasa, ko maye gurbin PCM.

Idan gwajin da ya gabata ya ci gaba kuma kun ci gaba da karɓar P02FA, zai fi dacewa yana nuna kuskuren DIAFCS, kodayake PCM da ta gaza ba za a iya cire shi ba har sai an maye gurbin DIAFCS.
