OBD-II Lambar Matsala - P0121 Bayanin Fasaha

P0121 - Sensor Matsayin Maƙura/Canja Matsala/Matsalolin Aiki.

DTC P0121 yana faruwa lokacin da injin sarrafa injin (ECU, ECM ko PCM) ya gano na'urar firikwensin matsayi mara kyau (TPS - firikwensin matsayi), wanda kuma ake kira potentiometer, wanda ke aika ƙimar da ba daidai ba bisa ga ƙa'idodi.

Menene ma'anar lambar matsala P0121?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye take. Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Na'urar firikwensin matsayi na ma'aunin ma'aunin ƙarfi ne wanda ke auna adadin buɗe maƙura. Yayin da aka buɗe maƙura, karatun (ana auna a volts) yana ƙaruwa.

Tsarin sarrafa wutar lantarki (PCM) yana ba da siginar nuni na 5V zuwa Sensor Matsayin Maɗaukaki (TPS) kuma galibi kuma ga ƙasa. Gabaɗaya ma'auni: rago = 5V; cikakken maƙura = 4.5 volts. Idan PCM ta gano cewa kushin maƙera ya fi girma ko ƙasa da yadda ya kamata ga wani RPM, zai saita wannan lambar.

Bayyanar cututtuka

Alamomin lambar matsala P0121 na iya haɗawa da:

  • An haskaka Fitilar Manuniya (MIL) (Duba Hasken Injin ko Sabis na Injin Ba da daɗewa ba)
  • Ƙuntatawa na ɗan lokaci yayin hanzari ko raguwa
  • Tura hayaƙin baki yayin hanzarta
  • Ba ya farawa
  • Kunna hasken faɗakarwar injin daidai.
  • Injin gabaɗaya na rashin aiki, wanda zai iya haifar da ɓarna.
  • Matsaloli tare da hanzarin motsi.
  • Matsaloli da fara injin.
  • Ƙara yawan man fetur.

Koyaya, waɗannan alamomin na iya fitowa a haɗe tare da wasu lambobin kuskure.

Abubuwan da suka dace don P0121 code

Matsakaicin matsayi na firikwensin yana yin aikin saka idanu da ƙayyade kusurwar buɗewar wannan damper. Ana aika bayanan da aka rubuta zuwa sashin kula da injin, wanda ke amfani da shi don ƙididdige adadin man da ake buƙata don allura a cikin kewaye don cimma cikakkiyar konewa.
