P0402 Yakawandisa Kuneta Gesi Kudzokorodza Kuyerera Kwakaonekwa

P0402 - Tsanangudzo Yehunyanzvi

Yakawandisa exhaust gasi recirculation (EGR) kuyerera kwaonekwa.

P0402 ndeye generic OBD-II kodhi yakaonekwa neinjini inodzora module (ECM) inoratidza kuti injini inopedza gasi recirculation (EGR) vharafu iri kubvumira yakawandisa kudzokororwa gasi rekuburitsa kana yakarairwa kuvhura iyo yakawanda yakawanda gasi kuyerera.

Ko dambudziko rekodhi P0402 rinorevei?

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.

EGR inomirira Exhaust Gesi Kudzokorodza. Icho chikamu chemotokari yekudzimisa sisitimu uye inoshandiswa kudzikisa kupisa tembiricha uye kumanikidza kuitira kudzora nitrogen oxides.

Kazhinji, iyo yekumesa gasi yekudzokorora sisitimu ine zvikamu zvitatu: iyo yekumesa gasi yekudzokorora vharuvhu, iyo actuator solenoid uye mutsauko wekumanikidza sensor (DPF). Izvi zvinhu zvinoshanda pamwechete kupa huwandu hwakaringana hwekudzokorodza zvichienderana neinjini tembiricha, mutoro, nezvimwe. P0402 kodhi inoreva kuti OBD yaona huwandu hwakawanda hweESR.

Zviratidzo

Unogona kucherechedza matambudziko nekubata, semuenzaniso, injini inogona kukundikana kana idling. Panogona kunge paine zvimwe zviratidzo futi.

• Chiedza cheCheck Engine chichauya uye kodhi ichachengetwa muECM.
• Injini inogona kuita rough kana vharuvhu yakanamira panzvimbo yakashama.
• Injini yeEGR system inogona kunge iine exhaust inodonha pane yekumashure sensor.

Zvikonzero zveP0402 kodhi

Iyo P0402 kodhi ingangoreva kuti chimwe kana zvimwe zvezviitiko zvinotevera zvaitika:

• Iyo DPFE (Differential Pressure) sensor haina kukwana uye inoda kutsiviwa.
• Exhaust gasi recirculation yakavharwa (ingangoita kabhoni kuvaka-kumusoro).
• Pedza gasi kudzokorodza vharafu yakaremara
• Iyo yekudzimisa gasi yekudzora vharuvhu inogona kusashama nekuda kwekushayikwa kwemhepo.

Mhinduro dzinogoneka

Panyaya yeP0402, vanhu vanowanzotsiva EGR valve, asi dambudziko rinodzoka. Iyo inonyanya kugadziriswa ndeyekutsiva iyo DPFE sensor.

• Tarisa iwo magetsi pane iyo DPFE sensor pane ese asina basa uye akavhura EGR.
• Tsiva DPFE sensor.

Yakabatana EGR Makodhi: P0400, P0401, P0403, P0404, P0405, P0406, P0407, P0408, P0409

SEI MACHANIC DIAGNOSTIC CODE P0402?

• Inotarisa data inomisa furemu makodhi uye zvinyorwa kuratidza dambudziko.
• Inodzima injini uye ETC makodhi uye bvunzo dzemugwagwa kuti uone kana kodhi inodzoka.
• Ongorora nemeso mavacuum hoses, wiring, zvinongedzo kune EGR valve uye control solenoid, uye EGR tembiricha sensor uye kumashure kudzvinyirira sensor.
• Inodzima uye bvunzo kana EGR vharafu vacuum inogona kuiswa kuvharuvhu apo solenoid yekutonga inovhura pachiedza kusvika pakati nepakati kukurumidza, kwete kungozara kuvhurika.
• Inotarisa inoshandura inoshandura kukuvara kana yakawandisa kumashure kumanikidza muEGR system.
• Inobvisa EGR vharafu uye tembiricha sensor kutarisa kana kabhoni yakabata EGR vharafu yakavhurika uye kabhoni iri kuvharira EGR purge port, ichidzivirira vharafu kuti isavhuvhute kunze kwevacuum.

ZVIKANGANISO ZVAUNOGONA KUONA CODE P0402

• Dzorera EGR valve pasina kutarisa EGR pressure sensor kuti uone kuti inogona kudzora kuvhurwa kweEGR valve.
• Usatarise kana vharafu yeEGR yakabatwa nechidimbu chemarasha chakavhurika usati waitsiva.

KODEI P0402 YAKAKANYA SEI?

• Kuwedzera gasi kudzokororwa nekuyerera kwakanyanya kunogona kukonzera injini kuzununguka kana kumira pakukwirisa, kana kuita kuti injini isashande yakaoma.
• Iyo yakabatiswa Cheka Injini mwenje ichaita kuti mota ikunde bvunzo dzekuburitsa.
• Kana iyo catalytic converter yakavharwa ichikonzera iyo kodhi, zvinogona kukonzera kurasikirwa kwesimba kana injini kutanga.

KUGADZIRIRA KUNOGONA KUGADZA CODE P0402?

• Kutsiva rakanamira rakavhurika EGR vharafu
• Kutsiva yakatyoka catalytic converter
• Kutsiva iyo EGR tembiricha sensor kana kuichenesa kubva kabhoni deposits kuti igadzirise kana yakanyora yakawandisa tembiricha shanduko.
• EGR Back Pressure Control Valve Replacement

KUWEDZERA MACOMMENTS KUTI UZIVE CODE P0402

Code P0402 inokonzereswa kana iyo EGR tembiricha sensor inoona shanduko huru yetembiricha pane iyo EGR yakarairwa kuvhura. Izvi zvinowanzokonzerwa neEGR backpressure control valve diaphragm iri kupeperetswa nekufamba kwenguva ne exhaust backpressure kana kuti chikamu chakavharwa chinokonzera.
