Ford Jaguar Fuel Common Rail Pressure Sensor 8W839F972AA

1. Kuwunika kwa mzere wakunja

Yezerani kuchuluka kwa kukana pakati pa terminal No.1 ndi terminal A08, terminal No.2 ndi terminal A43, ndi terminal No.3 ndi terminal A28 yokhala ndi ma multimeter kuti muweruze ngati pali dera lalifupi kapena cholakwika chotseguka mudera lakunja.

2. Sensor voltage muyeso

Zimitsani choyatsira, chotsani pulagi wamba wa njanji yothamanga, ndi kuyatsa choyatsira.Kuyeza voteji pakati pa No.3 mapeto a pulagi kachipangizo ndi pansi, voteji pakati pa No.2 mapeto ndi nthaka ayenera kukhala pafupifupi 0.5V, ndi voteji pakati pa No.1 mapeto ndi nthaka ayenera kukhala 0V.Pansi pazikhalidwe zodziwika bwino, voteji kumapeto kwa No.2 iyenera kuwonjezeka ndi kuwonjezeka kwa phokoso, mwinamwake zikhoza kuweruzidwa kuti kutulutsa kwa chizindikiro cha sensa n'kwachilendo.

3. Kuzindikira mtsinje wa data

Werengani mayendedwe amtundu wamagetsi amafuta a injini ndi chida chapadera chodziwira, zindikirani malo osagwira ntchito, kusintha kwamphamvu kwamafuta ndikuwonjezeka kwa throttle, ndikuweruza kusintha kwamagetsi kwa sensor pressure ya njanji.

(1) Pamene kutentha kozizira kwa injini ya dizilo kufika pa 80 ℃ ndipo injini ya dizilo ikuyenda pa liwiro lachabechabe, mphamvu yotulutsa mphamvu ya njanji iyenera kukhala pafupifupi 1V, ndi kuthamanga kwa njanji yamafuta ndi mtengo wake. Kuthamanga kwa njanji ndi pafupifupi 25.00MPa.Mtengo wokhazikika wa njanji uli pafupi kwambiri ndi mtengo wamagetsi amtundu wamafuta.

(2) Mukaponda pa accelerator pedal pang'onopang'ono ndikuwonjezera liwiro la injini ya dizilo, kuchuluka kwa data kwa dongosolo la kuthamanga kwa njanji kumawonjezeka pang'onopang'ono, ndipo kuchuluka kwa kuthamanga kwa njanji, kuthamanga kwa njanji ndi 145.00MPa , ndi mphamvu yowonjezera yotulutsa mphamvu ya njanji ya njanji ndi 4.5V V .

4, wamba cholakwika chodabwitsa

Pamene njanji yamagetsi yamagetsi ikulephera (monga kumasula), injini ya dizilo silingayambe, injiniyo idzagwedezeka pambuyo poyambira, liwiro lopanda ntchito lidzakhala losakhazikika, utsi wambiri wakuda udzatulutsidwa panthawi yothamanga, ndipo kuthamanga kudzakhala kotheka. ofooka.Mitundu yosiyanasiyana imagwiritsa ntchito njira zosiyanasiyana zowongolera injini.Zolakwa zenizeni zimasiyana kuchokera ku chitsanzo kupita ku chitsanzo.

(1) Pamene wamba njanji kuthamanga sensa kulephera, injini dizilo sangathe anayambitsa.

(2) Pamene njanji yamagetsi yamagetsi ikulephera, injini ya dizilo imatha kuyamba ndikuyenda bwino, koma injiniyo imakhala yochepa mu torque.

(3) Ma code olakwika wamba pomwe njanji yamagetsi wamba ikalephera (yatayika),

① injini singayambe ndikuthamanga: P0192,P0193;

② kusuntha kwa chizindikiro, malire a injini: P1912, P1192, P1193.
