P2120 Throttle Position Sensor / Chinja C Dunhu Kukanganisa

OBD-II DTC Dhata

Kukanganisika kweketani yesenenzi yechinzvimbo chevharufuru vharafu / chitiviri / chinja "D"

Izvi zvinorevei?

Iyi Yekuongorora Dambudziko Kodhi (DTC) ndeye yakajairika kodhi yekufambisa, zvinoreva kuti inoshanda kune OBD-II mota dzakashongedzwa. Kunyangwe yakajairika, chaiwo matanho ekugadzirisa anogona kusiyana zvichienderana neiyo mhando / modhi.

TPS (Throttle Position Sensor) i potentiometer yakaiswa pane throttle body. Inosarudza throttle angle. Kana iyo throttle ichifamba, iyo TPS inotumira chiratidzo kuPCM (Powertrain Control Module). Kazhinji 5-waya sensor: XNUMXV referensi kubva kuPCM kuenda kuTPS, pasi kubva kuPCM kuenda kuTPS, uye chiratidzo chekudzoka kubva kuTPS kuenda kuPCM.

Iyo TPS inotumira ruzivo rwechinzvimbo chakadzoka kuPCM pamusoro peiyi tambo yechiratidzo. Kana iyo throttle yakavharwa, iyo chiratidzo inenge 45 volts. Iine WOT (Wide Open Throttle), iyo TPS chiratidzo chemagetsi inosvika kune akazara mashanu volts. Kana iyo PCM yaona magetsi kunze kweyakajairika nzvimbo yekushandisa, P5 inoiswa. Tsamba "D" inoreva dunhu chairo, sensor, kana nzvimbo yedunhu chairo.

CHERECHEDZA: Iyo PCM inoziva kuti chero shanduko hombe munzvimbo yekumhanyisa zvinoreva shanduko inoenderana mukumanikidza kwakasiyana (MAP). Pane mamwe mamodheru, PCM inoongorora MAP uye TPS yekuenzanisa. Izvi zvinoreva kuti kana iyo PCM ikaona yakakura muzana inoshanduka munzvimbo yekumhanya, inotarisira kuona shanduko inoenderana mukumanikidza kwakawanda uye zvinopesana. Kana iye akasingaone shanduko iyi yekuenzanisa, P2120 inogona kusetwa. Izvi hazvishande kune ese mamodheru.

zviratidzo

Zviratidzo zvinogona kuitika zvinosanganisira:

• MIL Kuvhenekera (Chisina Kushanda Chiratidziro)
• Idle kana mugwagwa mukuru unopisa moto
• Hunhu husina basa
• Ngaarege kuva simbe
• Pamwe anotanga uye matanga

zvikonzero

Zvimwe zvinogona kukonzeresa P2120 kodhi zvinosanganisira:

• Yakadzika throttle kudzoka chitubu
• Ngura pane MAP kana TPS chinongedzo
• Bhandi risiri iro rinokonzeresa kupenga
• TPS yakaipa
• PC yakaipa

Mhinduro dzinogoneka

Kana iwe uine mukana wekushandisa scan, tarisa iyo TPS voltage neKOEO (Engine Off Key). Iine throttle yakavharwa, iyo voltage inofanirwa kuve ingangoita 45 V. Inofanira kukwira zvishoma nezvishoma kusvika kungangoita 4.5-5 volts apo iwe unosunda iko kubhabhadzira. Dzimwe nguva, iyo chete iyo oscilloscope ndiyo inogona kutora iyo periodic voltage spikes yechiratidzo cheTPS. Kana iwe ukaona kutadza muTPS kutsvaira voltage, chinja iyo TPS.

CHERECHEDZA. Mamwe masensa eTPS anoda kugadziridzwa kwakanaka. Kana usinganzwe wakasununguka kushandisa DVOM (Dhijitari Volt Ohmmeter) kumisikidza TPS yako itsva, bheji rako rakanakisa kuendesa mota yako kuchitoro. Kana iyo voltage isiri 45V (+ kana -3V kana zvakadaro) ine throttle yakavharwa, kana kana kuverenga kwakamira, bvisa iyo TPS yekubatanidza. Uchishandisa KOEO, tarisa 5V referensi pane yekubatanidza uye ivhu rakanaka. Iwe unogona kuyedza dhizaini yechiratidzo nekufambisa fusible waya pakati pepasi redunhu reTPS yekubatanidza uye chiratidzo chedunhu. Kana iyo TPS yekuverenga pane yekuongorora chishandiso ikozvino yaverenga zero, tsiva iyo TPS. Zvisinei, kana izvi zvisingashandure kuverenga kusvika zero, tarisa kuvhurika kana kupfupika muwaya yechiratidzo, uye kana pasina chinowanikwa, fungidzira PCM yakaipa. Kana kushandiswa kweiyo TPS harness kuchikonzera chero shanduko mukusaita, saka fungidzira kuti TPS yakaipa.
