Mukurongeka, zvinofanirwa kucherechedzwa kuti sensor iyi, kusiyana nemamwe akawanda, inogona kudzoserwa kune yayo yekushanda simba, ndiko kuti, kwete kutsiviwa. Dzimwe nguva kuchenesa kwekutanga kunobatsirawo (inoda kuitwa nekungwarira).

Kutarisa kushanda kweiyo inopinza tembiricha yemhepo sensor yakagadzirwa nemagetsi multimeter.

Kuongorora masensa

Muzviitiko zvakawanda, maitiro ekuongorora ari nyore uye haatore nguva yakawanda. Usati waita cheki, zvinokurudzirwa kuongorora ndangariro yemagetsi control unit yezvikanganiso uchishandisa yakakosha scanner (semuenzaniso, yakakurumbira ELM 327 mudziyo kana yakaenzana nayo). Izvi zvinorerutsa kuongororwa kwesese sensor uye kuparara kwemota yese.

Dzimwe nguva mamiriro ezvinhu anomuka kana nzvimbo yeimwe sensor isingazivikanwe. Muchiitiko ichi, zviri nani kutsvaga rubatsiro kubva mubhuku rekushandisa. zvakare pamasaiti akasarudzika pane ruzivo nezve chinzvimbo che sensors pane chaiwo mota modhi.

mhedziso

Usati watarisa imwe sensor, unofanirwa kuve neshuwa kuti zviratidzo zvekutadza zvinonyatso kutadza kweimwe sensor. Kana iwe uine kusava nechokwadi pamusoro peizvi, zviri nani kutsvaga rubatsiro kubva kumotokari yemotokari. ndiyo cheki muzviitiko zvakawanda inoitwa uchishandisa multimeter yemagetsi inokwanisa kuyera kupikisa kwemagetsi uye DC voltage muhuwandu kusvika ku12 volts. Naizvozvo, tenga mudziyo wakadaro kana iwewo usinawo. Izvo hazvifanirwe kutora sampuli dzinodhura, chishandiso kubva muchikamu chemutengo wepakati chakakwana (haufanire kutenga yakachipa zvakanyanya, sezvo inogona kuratidza data risiri iro). Zvakanaka, kuti ubvise masensa, iwe unofanirwa kuve neakajairwa maturusi ekukiya paruoko - wrenches, screwdrivers, zvichingodaro.
