Sebopeho sa sensor ea khatello ea bongata ba ho kenella
Hobane ho na le potoloho ea amplifier ka hare ho sensor ea khatello ea manifold, e hloka lithapo tse tharo kaofela tsa mohala oa motlakase, mohala oa fatše le mohala oa tlhahiso ea lets'oao, tse nang le li-terminal tse tharo li-terminal tsa wiring, ka ho latellana, seteishene sa motlakase (Vcc), seteishene sa fatše (E) le seteishene sa tlhahiso ea lets'oao (PIM), 'me li-terminal tse tharo li hokahantsoe le ECU ea khomphutha ea taolo ka sehokelo sa terata le terata.
E le ho fokotsa ho thothomela ha dikarolo tsa elektroniki tsa kahare tsa sensor ya khatello ya intake manifold, hangata e kenngwa sebakeng seo ho thothomela ha koloi ho leng honyenyane, le ka hodima sebaka se seholo sa moya o kenang ho thibela kgase e tswang ho intake manifold hore e se ke ya hlasela sensor ya kgatello. Ho feta moo, sensor ya kgatello ya intake manifold e amohela kgatello ya phaephe ya intake ho tloha tlase ho thibela karolo e utlwang matshwao hore e se ke ya silafala, kahoo kgase ya phaephe ya intake e bokellwang ho tswa ho intake manifold haufi le throttle ka hara tube ya rabara e fihlellwa ho tloha pheletsong e ka tlase ya sensor ya kgatello ya manifold.

Ha o sheba, fumana feela phaephe ya rabara ho tswa ho intake manifold haufi le pheletso ya throttle ho fumana sensor ya kgatello ya manifold koloing. Taba ya pele, ha senotlolo sa ho itsamaisa se kwetswe, hlahloba hore sehokelo sa terata sa sensor ya kgatello ya manifold ya intake se hokahane hantle mme phaephe ya rabara e timme. Ebe o qala enjene ho bona hore na phaephe ya rabara ha e kwalwa ka thata ebile ha e dutle.
2. Teko ea lisebelisoa
(1) Bulela switch ea ho hotetsa (BULELA), 'me u leke boleng ba motlakase pakeng tsa terminal Vcc le E2 ka DC voltage stop ea multimeter (DCV-20). Boleng ba motlakase ke boleng ba motlakase oa phepelo ea motlakase bo ekelitsoeng ke ECU ho sensor ea khatello ea manifold.

Boleng ba motlakase bo lokela ho eketseha ka tatellano le kholo ea khatello e mpe e sebelisitsoeng, ho seng joalo, ho bontša hore potoloho ea ho lemoha matšoao ho sensor e na le phoso 'me e lokela ho nkeloa sebaka.
Sensor ea khatello ea intake manifold e hokae?
Sensor ea khatello ea intake manifold ke sensor e kentsoeng phaepheng ea khase ea intake manifold, eo lithapo tse tharo tsa eona, e 'ngoe ke ea li-volts tse 5, e 'ngoe ke ea li-volts tse 5 tsa tsela ea ho khutla, ke hore, mola o fosahetseng, 'me e 'ngoe ke mola oa lets'oao bakeng sa Ecu.
Sensor ea khatello ea intake manifold ke mofuta oa bohlokoa haholo oa sensor ho Mofuta oa D, ke hore, litsamaiso tsa ente ea mafura a lebelo le phahameng, e bapalang karolo ea ho fetola phetoho ea khatello ho intake manifold hore e be lets'oao la motlakase.
Khomphutha ya taolo (ECU) e fumana hore na moya o kenang ka har'a silindara o kae ho latela lets'oao lena le lebelo la enjene (lets'oao le fanoang ke sensor ea lebelo la enjene e kentsoeng ho mofani oa thepa).
Sensor ea khatello ea ho kenella e lemoha khatello e felletseng ea manifold ea ho kenella ka mor'a lefito le valve, 'me e lemoha phetoho ea khatello e felletseng ho manifold ho latela lebelo la enjene le mojaro.
Ebe e fetoloa motlakase oa lets'oao ebe e romeloa ho molaoli oa elektroniki (ECU), ea laolang bongata ba ente ea mafura ho latela boholo ba motlakase ona oa lets'oao.
