Khoutu ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang, e bolelang hore e sebetsa ho likoloi tse nang le thepa ea khatello ea mafura ea OBD-II (Chevrolet, Ford, GMC, Chrysler, Toyota, jj.). Leha e le ka tlhaho, mehato e nepahetseng ea ho lokisa e ka fapana ho latela sebopeho / mmotlolo. Ho makatsang ke hore khoutu ena e bonahala e atile haholo ho makoloi a GM (GMC, Chevrolet, jj.) Mme e kanna ea tsamaea le khoutu ea P018C le / kapa likhoutu tse ling ka nako e le ngoe.

Likoloi tse ngata tsa sejoale-joale li na le sensor ea khatello ea mafura (FPS). FPS ke e 'ngoe ea lisebelisoa tsa mantlha tsa module ea taolo ea powertrain (PCM) ho laola pompo ea mafura le / kapa sesebelisoa sa mafura.

Sensor khatello ea mafura ke mofuta oa sensor e bitsoang transducer. Mofuta ona oa sensor o fetola ho hanyetsa ha oona ka hare ka khatello. FPS hangata e phahamisetsoa ho seporo sa mafura kapa mohala oa mafura. Hangata ho na le lithapo tse tharo tse eang FPS: referense, pontšo le fatše. Sensor e fumana motlakase oa litšupiso ho tsoa ho PCM (hangata li-volts tse 5) ebe e khutlisetsa motlakase oa maikutlo o lumellanang le khatello ea mafura.

Tabeng ea khoutu ena, "B" e bonts'a hore bothata ke karolo ea ketane ea sistimi eseng letšoao kapa karolo e itseng.

P018B e behiloe ha PCM e lemoha bothata ba tšebetso ka senotlolo sa khatello ea mafura. Likhoutu tse amanang li kenyelletsa P018A, P018C, P018D, le P018E.

Mohlala oa khatello ea mafura:

Ho tiea ha khoutu le matšoao

Bohloko ba likhoutu tsena bo mahareng ho isa ho bo matla. Maemong a mang, likhoutu tsena li ka etsa hore koloi e se ke ea qala. Ho khothalletsoa ho lokisa khoutu ena kapele kamoo ho ka khonehang.

Matšoao a P018B DTC a ka kenyelletsa:

• Enjene e thata ho qala kapa e ke ke ea qala
• Ts'ebetso e mpe ea enjene

Lisosa Tse Tloaelehileng Tsa DTC Ena

Mabaka a ka bang teng a khoutu ena a ka kenyelletsa:

• Sephahla sa khatello ea mafura se nang le phoso
• Mathata a tsamaisang mafura
• Mathata a wiring
• PCM e nang le phoso

Mekhoa ea ho hlahloba le ho lokisa

Qala ka ho lekola sensor ea khatello ea mafura le wiring e amanang le eona. Batla likhokahano tse hlephileng, likhoele tse senyehileng, jj. Haeba tšenyo e fumanoe, lokisa kamoo ho hlokahalang, hlakola khoutu 'me u bone hore na ea khutla. Ebe u sheba li-bulletins tsa lits'ebeletso tsa tekheniki bakeng sa bothata. Haeba ho se letho le fumanoang, o tla hloka ho fetela ho li-diagnostics tsa sistimi ka mehato.

E latelang ke ts'ebetso e akaretsang ha tlhahlobo ea khoutu ena e fapana le koloi le koloi. Ho lekola sistimi ka nepo, o hloka ho sheba sethala sa "diagnostic flow" sa moetsi.

Lekola wiring

Pele o tsoela pele, o hloka ho sheba lits'oants'o tsa wiring tsa fektheri ho tseba hore na ke mehala efe. Autozone e fana ka litataiso tsa mahala tsa ho lokisa marang-rang bakeng sa likoloi tse ngata mme ALLDATA e fana ka peeletso ea koloi e le 'ngoe.

Lekola karolo ea potoloho ea motlakase.

Ha koloi e khantšitsoe, sebelisa multimeter ea digital e behiloeng ho voltage ea DC ho hlahloba motlakase oa litšupiso (hangata li-volts tse 5) ho tloha PCM. Ho etsa sena, hokela meter e fosahetseng fatše, 'me mitha e nepahetseng e lebisa ho B+ sensor ka lehlakoreng la sehokelo. Haeba ho se na lets'oao la litšupiso, hokela meter sete ho ohms (ignition OFF) lipakeng tsa terminal ea voltage ea referense ho sensor ea khatello ea mafura le terminal ea voltage ea referense ho PCM. Haeba ho baloa ha meter ho tsoa ho mamello (OL), ho na le potoloho e bulehileng pakeng tsa PCM le sensor e lokelang ho fumanoa le ho lokisoa. Haeba counter e bala boleng ba linomoro, ho na le tsoelo-pele.

Haeba ntho e 'ngoe le e' ngoe e le hantle ho fihlela joale, u tla batla ho hlahloba hore na matla a tsoa ho PCM. Ho etsa sena, bulela mollo 'me u behe meter hore e be voltage e tsitsitseng. Hokela meter positive lead ho terminal ea voltage ea PCM le lead lead ho ea fatše. Haeba ho se na voltage ea litšupiso ho tsoa ho PCM, mohlomong PCM e fosahetse. Leha ho le joalo, li-PCM ha li hlolehe hangata, kahoo ke mohopolo o motle ho hlahloba mosebetsi oa hau habeli ho fihlela moo.

Lekola karolo ea motheo ea potoloho.

Ha koloi e koetsoe, sebelisa DMM ea resistor ho leka ho tsoela pele fatše. Kopanya mitha pakeng tsa setsi sa fatše sa sehokedi sa khatello ea mafura le mochini oa chassis. Haeba khaontara e bala boleng ba linomoro, ho na le tsoelopele. Haeba ho bala ha metara ho tsoa mamellong (OL), ho na le potoloho e bulehileng lipakeng tsa PCM le senorara se hlokang ho fumaneha le ho lokisoa.

Lekola karolo ea potoloho ea lets'oao la ho khutla.

Tlosa mollo oa koloi 'me u behe boleng ba khanyetso ho multimeter. Hokela teko e le 'ngoe ho terminal ea lets'oao la ho khutla ho PCM le e 'ngoe ho terminal ea ho khutla sehokelong sa sensor. Haeba letšoao le bontša ho tsoa (OL), ho na le potoloho e bulehileng pakeng tsa PCM le sensor e hlokang ho lokisoa. Haeba counter e bala boleng ba linomoro, ho na le tsoelo-pele.

Bapisa ho bala ho tsoa ho sensor ea khatello ea mafura le khatello ea 'nete ea mafura.

Liteko tse entsoeng ho fihlela mona li bontša hore potoloho ea kutlo ea khatello ea mafura e lokile. Ebe o tla batla ho itlhahloba ka boeona ho ipapisa le khatello ea mafura. Ho etsa sena, qala ka ho hokela sekhahla sa khatello ea mochini ho seporo sa mafura. Ebe o hokela sesebelisoa sa sesebelisoa ho koloi ebe u khetha khetho ea data ea FPS ho e sheba. Qala enjene ha u ntse u shebile sesebelisoa sa "scan" sa khatello ea mafura le data ea sensor ea FPS. Haeba ho bala ho se ka har'a psi e 'ngoe ho e' ngoe, sensor e fosahetse mme e lokela ho nkeloa sebaka. Haeba lipalo ka bobeli li le tlasa khatello ea peterole e boletsoeng ke moetsi, FPS ha e na molato. Sebakeng seo, ho kanna ha ba le bothata ba phepelo ea mafura joalo ka pompo ea peterole e hlotsoeng e tla hloka tlhahlobo le tokiso.
