Likoloi tsa sejoale-joale li itšetlehile ka sistimi ea On-Board Diagnostics II (OBD-II) ho beha leihlo tšebetso ea enjine le mesi. Ha koloi ea hau e hloleha ho etsa tlhahlobo ea mesi, boema-kepe ba tlhahlobo ea OBD-II e ba sesebelisoa sa hau se setle sa ho tseba le ho rarolla mathata. Ka tlase, re hlalosa hore na li-scanner tsa OBD-II li sebetsa joang le ho fana ka tharollo bakeng sa likhoutu tse 10 tse tloaelehileng tsa mathata tse ka bakang ho hloleha ha mesi.
Kamoo Li-scanner tsa OBD-II li Thusang Kateng ho Lemoha Mathata a Phallo
- Bala Likhoutu tsa Mathata a Tlhahlobo (DTCs):
- Liskena tsa OBD-II li fumana likhoutu (mohlala, P0171, P0420) tse supang ho se sebetse hantle ha sistimi ho amang mesi.
- Mohlala: AP0420khoutu e bonts'a ho se sebetse hantle ho fetolelang catalytic.
- Live Data Streaming:
- Lekola lintlha tsa sensor ea nako ea 'nete (mohlala, motlakase oa sensor ea oksijene, ho fokotsa mafura) ho hloaea liphoso.
- Sheba "Readiness Monitors":
- Liteko tsa mesi li hloka hore li-monitor tsohle (mohlala, EVAP, catalytic converter) li "itokisitse." Li-scanner li netefatsa haeba litsamaiso li qetile ho itlhahloba.
- Fetola Boitsebiso ba Frame:
- Hlahloba maemo a bolokiloeng (enjene ea mojaro, RPM, mocheso) nakong eo khoutu e neng e hlahisoa ho ikatisetsa le ho hlahloba mathata.
- Hlakola Likhoutu 'me U Lokise Lihlahlobi:
- Kamora ho lokisoa, seta sistimi bocha ho netefatsa litokiso le ho itokisetsa ho e hlahloba hape.
Likhoutu tse 10 tse Tloaelehileng tsa OBD-II tse Bakang ho Hlōleha Mosi
1. P0420/P0430 - Tšebeliso e Ntle ea Sisteme ea Catalyst ka tlase ho moeli

- Kenya sebaka sa catalytic converter haeba e senyehile.
2. P0171/P0174 – Tsamaiso e Lean haholo
- Lebaka:Moya o dutla, sensara ya MAF e fosahetseng, kapa pompo e fokolang ya mafura.
- Lokisa:
- Hlahloba ho lutla ha vacuum (li-hoses tse phatlohileng, li-gaskets tsa ho noa).
- Hloekisa / fetola MAF sensor.
- Leka khatello ea mafura.
3. P0442 - Leak e Nyenyane ea Mouoane oa Mouoane
- Lebaka:Sekoahelo sa khase se hlephileng, hose ea EVAP e petsohileng, kapa valve e nang le phoso ea ho hloekisa.
- Lokisa:
- Tiisa kapa u nke sebaka sa sekoahelo sa khase.
- Lekola mochini oa EVAP ho fumana moo ho lutlang teng.
4. P0300 – Random/Multiple Cylinder Misfire
- Lebaka:Li-spark plugs tse tsofetseng, li-coil tse timang hampe kapa khatello e tlase.
- Lokisa:
- Tlosa li-spark plugs/likhoele tse tukang.
- Etsa tlhahlobo ea khatello.
5. P0401 - Phallo ea Exhaust Gas Recirculation (EGR) Ha ea lekana
- Lebaka:Litemana tsa EGR tse koetsoeng kapa valve ea EGR e fosahetseng.
- Lokisa:
- Hloekisa carbon buildup ho tloha EGR valve le liphasejeng.
- Kenya sebaka sa valve ea EGR e khomaretsoeng.
6. P0133 - O2 Sensor Circuit e Butle Karabo (Bank 1, Sensor 1)
- Lebaka:Sensor ea oksijene e senyehileng holimo.
- Lokisa:
- Kenya sebaka sa sensor ea oksijene.
- Sheba lithapo bakeng sa tšenyo.
7. P0455 - Leak e kholo ea EVAP
- Lebaka:Hose ea EVAP e khaotsoeng, canister ea mashala e senyehileng, kapa tanka ea mafura e senyehileng.
- Lokisa:
- Lekola lithapo tsa EVAP le likhokahano.
- Kenya sebaka sa sekoti sa mashala haeba se petsohile.
8. P0128 – Ho Se sebetse hantle ha Thermostat e Phodileng
- Lebaka:Thermostat e ile ea lula e butsoe, e etsa hore enjene e sebetse e pholile haholo.
- Lokisa:
- Fetola thermostat.
- Etsa bonnete ba hore pholiso e phalla hantle.
9. P0446 - EVAP Vent Control Potoloho e sa sebetseng hantle
- Lebaka:Phoso ea moea ea solenoid kapa mohala o koetsoeng oa moea.
- Lokisa:
- Lekola moea oa solenoid.
- Hlakola lithōle moleng oa moea.
10. P1133 – Fuel Air Metering Correlation (Toyota/Lexus)
- Lebaka:Ho se leka-lekane ha moea / mafura ka lebaka la sensor ea MAF kapa ho lutla ha vacuum.
- Lokisa:
- Hloekisa MAF sensor.
- Hlahloba moea o lutlang o sa lekanyetsoang.
Mehato ea ho Etsa bonnete ba Katleho ea Teko ea Emissions
- Lekola Likhoutu Esale Pele:Sebelisa sehatisi sa OBD-II ho tseba mathata libeke pele ho tlhahlobo.
- Lokisa Hang-hang:Rarolla mathata a manyane (mohlala, ho lutla ha khase) pele a ka hlahisa likhoutu tse matla.
- Qetello ea Libaesekele:Kamora ho hlakola likhoutu, tlatsa potoloho ea drive ho seta li-monitor tsa ho itokisetsa bocha.
- Sekena sa Teko Pele:Netefatsa hore ha ho na likhoutu tse khutlang 'me li-monitor tsohle li "itokisitse" pele li hlahlojoa.
Malebela a ho Qetela
- Tsetela hosekenari sa mahareng sa OBD-II(mohlala, iKiKin) bakeng sa tlhahlobo e felletseng ea khoutu.
- Bakeng sa likhoutu tse rarahaneng (mohlala, ho hloleha ha li-converter), ikopanye le setsebi sa mak'henike.
- Tlhokomelo ea kamehla (li-spark plug, li-filters tsa moea) li thibela litaba tse ngata tse amanang le mesi.
Ka ho sebelisa bokhoni ba hau ba sehatisi sa OBD-II, o ka hlahloba le ho lokisa mathata a mesi ka nepo, o etsa bonnete ba hore o feta tlhahlobong e latelang!
