Khoutu ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang, ho bolelang hore e sebetsa ho likoloi tse nang le thepa ea OBD-II ho kenyeletsoa empa ho sa lekanyetsoe ho Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, jj. Mehato e khethehileng ea ho lokisa e ka fapana ho latela mohlala.

Likoloi tse nang le Variable Valve Timing (VVT), li-camshaft li laoloa ke li-hydraulic actuators tse feptjoang ke sistimi ea oli ea enjene ka li-solenoids tse tsoang ho Engine Control Module/Powertrain Control Module (ECM/PCM). ECM/PCM e hlokometse hore motsamao oa banka oa 1 exhaust camshaft o tsoile ka mokhoa o ikhethileng kapa ha o sebetse ka taelo. Block 1 e bua ka karolo ea # 1 ea silindara ea enjene - etsa bonnete ba hore u sheba lehlakore le nepahetseng ho latela litlhaloso tsa moetsi. The exhaust valve control solenoid hangata e fumaneha ka lehlakoreng le nang le mokelikeli o mongata oa hlooho ea silinda.

Oli ea Enjine - Lekola boemo ba oli ea enjine ho etsa bonnete ba hore tefiso ea oli ea enjene e lekane. Kaha li-actuator li sebetsa tlas'a khatello ea oli, palo e nepahetseng ea oli e bohlokoa ho netefatsa hore sistimi ea VVT e sebetsa hantle. Mokelikeli o litšila kapa o silafetseng o ka baka ho bokellana ho ka lebisang ho hloleheng ha taolo ea solenoid kapa camshaft actuator.

Laola Solenoid - The camshaft control solenoid e ka lekoa bakeng sa ho tsoela pele ka digital volt / ohmmeter (DVOM) e sebelisa ts'ebetso ea tekanyo ea ho hanyetsa ka ho khaola sehokelo sa solenoid harness le ho hlahloba khanyetso ea solenoid ka ho sebelisa (+) le (-) DVOM e etella pele ho e 'ngoe le e 'ngoe. Theminale. Netefatsa hore khanyetso ea ka hare e ka har'a litlhaloso tsa moetsi, haeba li teng. Haeba ho hanyetsa ho le ka har'a litlhaloso, tlosa solenoid ea taolo ho netefatsa hore ha e silafatsoe, kapa haeba ho na le tšenyo ea li-o-rings, ho baka tahlehelo ea khatello ea oli.

Camshaft Drive - Mokhanni oa camshaft ke sesebelisoa sa mochini se laoloang ke khatello ea ka hare ea selemo 'me se laoloa ke oli e fanoang ke solenoid ea taolo. Ha khatello ea oli e sa sebelisoe, e ea sebakeng se "sireletsehileng". Sheba mokhoa o khothaletsoang ke moetsi oa ho tlosa camshaft position actuator ho camshaft ea enjene ho netefatsa hore ha ho na ho lutla ho ka bakang tahlehelo ea khatello ea oli ho lithapo tsa phepelo / ho khutlisa hydraulic kapa ka har'a mochini ka boeona. Sheba ketane ea nako / lebanta le likarolo ho netefatsa hore li sebetsa hantle 'me li kentsoe sebakeng se nepahetseng holim'a lisebelisoa tsa camshaft.

ECM / PCM - ECM / PCM e laela solenoid ea taolo e sebelisa pontšo ea pulse-width modulated (PWM) ho laola nako ea ho tima / ho tima, e leng se etsang hore ho be le taolo ea khatello e sebelisoang ho tsamaisa mochine oa camshaft. Multimeter ea graphical kapa oscilloscope ea hlokahala ho sheba lets'oao la PWM ho netefatsa hore ECM/PCM e sebetsa hantle. Ho leka lets'oao la PWM, lead e ntle (+) e hokahantsoe lehlakoreng le ka tlase la solenoid ea taolo (haeba e fanoe ka voltage ea DC, e theohile) kapa lehlakoreng la matla la solenoid ea taolo (haeba e thehiloe ka ho sa feleng, taolo e nepahetseng) le negative (-) lead e amanang le motheo o tsebahalang. Haeba lets'oao la PWM le sa tsamaellane le liphetoho tsa enjene RPM, ECM/PCM e kanna ea ba bothata.
