P2120 Throttle Position Sensor / Whakawhiti C Huringa Porowhita

Pepaiti OBD-II DTC

Te koretake o te mekameka o te tuunga o te putunga purerehua / hiko / pana "D"

He aha te tikanga o tenei?

Ko tenei Waehere Raru Taatari (DTC) he waehere tuku noa, ko te tikanga e pa ana ki nga waka OBD-II. Ahakoa te nuinga, ko nga taahiraa whakatika motuhake ka rereke i te waitohu / tauira.

Ko te TPS (Throttle Position Sensor) he potentiometer kua utaina ki runga i te tinana katere. Ka whakatau i te koki throttle. I te wa e neke ana te kaareti, ka tukuna e te TPS he tohu ki te PCM (Powertrain Control Module). Ko te tikanga he pukoro 5-waea: XNUMXV tohutoro mai i te PCM ki te TPS, te whenua mai i te PCM ki te TPS, me te hokinga tohu mai i TPS ki te PCM.

Ka tukuna e te TPS nga korero tuuturu ki te PCM i runga i tenei waea tohu. Ka katia te kaawerewere, ko te tohu e tata ana ki te 45 volts. Ma te WOT (Whanui Open Throttle), ka toro atu te ngaohiko tohu TPS ki te 5 volts katoa. Ka kitea e te PCM tetahi ngaohiko i waho o te awhe whakahaere noa, ka whakatauhia te P2120. Ko te reta "D" e pa ana ki tetahi ara iahiko, kaitautoko, waahanga ranei o tetahi ara motuhake.

PANUI: E mohio ana te PCM ko te rereketanga nui o te tuunga kaupae he rereke te rereketanga o te pehanga maha (MAP). I runga i etahi tauira, ka aroturukihia e PCM te MAP me te TPS hei whakatairite. Ko te tikanga mena ka kite te PCM he rereketanga nui te rereketanga o te tuunga tuuroro, me tatari kia rereke te rereketanga o te pehanga maha me te tua atu. Mena kaore ia e kite i tenei rereketanga rereke, ka taea te whakarite P2120. Kaore tenei e pa ki nga tauira katoa.

tohu

Ko nga tohu ka taea te:

• Maama MIL (Tohu Mahinga)
• Te mangere, te kino ranei o te huanui
• He kounga pai kore mahi
• Kaore pea e mangere
• Akene ka tiimata ka tu

take

Ko nga take ka taea pea te waehere P2120:

• Puku kokiriu hoki mai puna
• Te waikura ki te MAP honohono TPS ranei
• Ma te whitiki he tika te haere, ka raru
• TPS Kino
• PCM Kino

He otinga ka taea

Mena ka uru atu koe ki tetahi taputapu karapa, tirohia te ngaohiko TPS me KOEO (Kī Mīhini Kore). Ka katia te kaarahi, me tata pea te hiko ki te 45 V. Kia piki ake ki te 4.5-5 volts i a koe e pana ana i te kaarahi. I etahi wa, ko te oscilloscope anake ka mau ki nga nekehanga hiko o te tohu TPS. Mena ka kite koe i te ngoikore o te ngaohiko taapiri TPS, whakakapihia te TPS.

FAKATOKANGA. Ko etahi o nga pūoko TPS e hiahia ana ki te whakatika pai. Ki te kore koe e pai ki te whakamahi i te DVOM (Digital Volt Ohmmeter) ki te whakarite i to TPS hou, ko to painga pai ko te kawe i to waka ki te toa. Mena karekau te ngaohiko i te 45V (+, -3V ranei) me te kati o te katere, mena ka mau te panui, momotuhia te hononga TPS. Ma te whakamahi i te KOEO, tirohia he tohutoro 5V i runga i te hono me te papa pai. Ka taea e koe te whakamatautau i te ara iahiko tohu ma te nuku i te waea karekau i waenga i te ara iahiko whenua o te hononga TPS me te ara iahiko tohu. Ki te panui te TPS i runga i te taputapu karapa inaianei ka panui kore, whakakapihia te TPS. Heoi, ki te kore tenei e huri i te panui ki te kore, tirohia he tuwhera, he poto ranei i roto i te waea tohu, a ki te kore e kitea, whakapae he PCM kino. Mēnā he panoni i te noho mangere ma te raweke i te taputapu TPS, ka whakapae he kino te TPS.

Me kaha ake te awhina mo te tohu p2120?

Mena kei te hiahia awhina tonu koe ki te DTC P2120, whakairihia he paatai ​​ki nga korero i raro o tenei tuhinga.

PANUI. I hoatuhia enei korero mo nga mahi korero noa iho. Kaore i te whakaarohia kia whakamahia hei taunakitanga mo te whakatika kaore matou i te kawenga mo tetahi mahi ka mahia e koe mo tetahi motuka. Katoa nga korero i runga i tenei papaanga e tiakina ana e te mana pupuri.
