Ford Jaguar Fuel Common Rail Pressure Sensor 8W839F972AA

1. Kuongororwa kwemutsara wekunze

Edza maitiro ekupikisa pakati pekuguma No.1 uye terminal A08, terminal No.2 uye terminal A43, uye terminal No.3 uye terminal A28 ine multimeter kutonga kana pane pfupi pfupi kana kushayikwa kwedunhu rakazaruka munharaunda yekunze.

2. Sensor voltage kuyerwa

Dzima switch yekubatidza, bvisa iyo yakajairwa njanji yekumanikidza sensor plug, uye batidza switch yekubatidza. Kuyera magetsi pakati peNo.3 kuguma kwepureji ye sensor uye pasi, mhepo pakati peNo.2 kuguma uye pasi inofanira kuva inenge 0.5V, uye mhepo pakati peNo.1 kuguma uye pasi inofanira kuva 0V. Pasi pemamiriro ezvinhu akaenzana, mhepo paNo.2 yekupedzisira inofanira kuwedzera nekuwedzera kweiyo throttle, kana zvisina kudaro inogona kutongwa kuti iyo sensor fault signal output haina kujairika.

3. Kuonekwa kwe data

Verenga iyo data kuyerera kweinjini yemafuta ekupa system ine yakakosha yekuongorora chiridzwa, tarisa iyo isingashande mamiriro, iyo oiri kudzvanywa shanduko nekuwedzera kweiyo throttle, uye kutonga kubuda kwemagetsi shanduko yenjanji yekumanikidza sensor.

(1) Kana tembiricha inotonhorera yeinjini yedhiziri yasvika 80 ℃ uye injini yedhiziri ichimhanya nekumhanya kusina basa, magetsi ekubuda kwenjanji yekumanikidza sensor anofanira kunge ari 1V, uye njanji yekumanikidza kwemafuta system uye kukosha kweiyo njanji inomanikidza zvese zviri zviviri nezve 25.00MPa. Iyo njanji yekumanikidza yekuisa kukosha iri padyo zvakanyanya neiyo njanji yekumanikidza kukosha kweiyo mafuta system.

(2) Kana uchitsika pane accelerator pedal zvishoma nezvishoma uye uchiwedzera kumhanya kweinjini yedhiziri, kukosha kwedata renjanji yekumanikidza system kunowedzera zvishoma nezvishoma, uye huwandu hwakanyanya hwekumanikidza njanji, njanji yekumanikidza seti kukosha uye chaiyo njanji kumanikidza kwemafuta system i145.00MPa , uye iyo yakanyanya kuburitsa voltage yenjanji pressure sensor ndeye 4.5V V.. Iyo yakayerwa (yekutarisa chete) kuyerera kwedata kunoratidzwa mutafura iri pazasi.

4, zvakajairika kukanganisa chiitiko

Kana iyo yakajairwa njanji yekumanikidza sensor inotadza (sekuburitsa), injini yedhiziri inogona kusatanga, injini inodedera mushure mekutanga, iyo isingashande inomhanya ichave isina kugadzikana, hutsi hwakawanda hutema huchaburitswa panguva yekuwedzera, uye kukurumidza kuchave. weak. Mhando dzakasiyana dzinotora nzira dzakasiyana dzekudzora injini. Izvo zvakakanganiswa zvinosiyana kubva kune modhi kuenda kune modhi.

(1) Kana iyo yakajairika njanji pressure sensor ikatadza, injini yedhiziri haigone kutangwa.

(2) Kana iyo yakajairwa njanji pressure sensor ikatadza, injini yedhiziri inogona kutanga uye kumhanya zvakajairika, asi injini inogumira mu torque.

(3) Yakajairika kukanganisa makodhi kana yakajairika njanji yekumanikidza sensor inotadza (yakarasika),

① injini haigoni kutanga uye kumhanya: P0192,P0193;

② chiratidzo chekudonha, injini torque muganho: P1912, P1192, P1193.
