Ford Jaguar Roj Common Rail Siab Sensor 8W839F972AA

1. Kev tshuaj xyuas kab sab nraud

Ntsuas qhov ntsuas qhov tseem ceeb ntawm lub davhlau ya nyob twg No.1 thiab davhlau ya nyob twg A08, davhlau ya nyob twg No.2 thiab davhlau ya nyob twg A43, thiab davhlau ya nyob twg No.3 thiab davhlau ya nyob twg A28 nrog ib tug multimeter los txiav txim seb puas muaj ib tug luv luv Circuit Court los yog ib tug qhib Circuit Court txhaum nyob rau hauv lub sab nraud Circuit Court.

2. Sensor voltage ntsuas

Tshem tawm qhov hluav taws xob hloov hluav taws xob, tshem tawm cov hluav taws xob hluav taws xob sib txuas hluav taws xob, thiab tig rau qhov hluav taws xob hloov hluav taws xob. Ntsuas qhov voltage ntawm No.3 kawg ntawm lub sensor plug thiab hauv av, qhov voltage ntawm No.2 kawg thiab hauv av yuav tsum yog 0.5V, thiab qhov voltage ntawm No.1 kawg thiab hauv av yuav tsum yog 0V. Raws li ib txwm muaj, qhov hluav taws xob ntawm No.2 kawg yuav tsum nce nrog qhov nce ntawm lub throttle, txwv tsis pub nws tuaj yeem txiav txim siab tias qhov ntsuas qhov tsis raug ntawm lub teeb liab tso tawm yog txawv txav.

3. Cov ntaub ntawv kwj kom paub

Nyeem cov ntaub ntawv khiav ntawm lub cav roj muab hluav taws xob nrog cov cuab yeej tshwj xeeb kuaj mob, kuaj xyuas lub xeev tsis ua haujlwm, cov roj hloov pauv nrog qhov nce ntawm lub throttle, thiab txiav txim siab qhov hloov pauv qhov hluav taws xob ntawm lub tsheb ciav hlau siab sensor.

(1) Thaum lub coolant kub ntawm lub cav diesel nce mus txog 80 ℃ thiab lub cav diesel khiav ntawm idle speed, cov zis voltage ntawm lub tsheb ciav hlau siab sensor yuav tsum yog li ntawm 1V, thiab rail siab ntawm cov roj system thiab cov nqi ntawm lub rail siab yog ob qho tib si txog 25.00MPa. Txoj kev tsheb ciav hlau qhov teeb tsa tus nqi yog ze heev rau kev tsheb ciav hlau siab tus nqi ntawm cov roj system.

(2) Thaum nce mus rau lub accelerator pedal maj mam thiab nce qhov ceev ntawm lub cav diesel, cov ntaub ntawv tus nqi ntawm rail siab system maj mam nce, thiab lub siab tshaj plaws qhov tseem ceeb ntawm kev tsheb nqaj hlau siab, rail siab teeb tus nqi thiab tiag rail siab ntawm roj system yog 145.00MPa , thiab qhov siab tshaj plaws tso zis voltage ntawm kev tsheb ciav hlau siab sensor yog 4.5V V.. Qhov ntsuas (rau kev siv nkaus xwb) cov ntaub ntawv ntws yog qhia hauv cov lus hauv qab no.

4, common fault phenomenon

Thaum lub tshuab hluav taws xob sib xyaw ua haujlwm tsis ua haujlwm (xws li kev tshem tawm), lub tshuab hluav taws xob tsis tuaj yeem pib, lub cav yuav tshee tom qab pib, qhov nrawm nrawm yuav tsis ruaj khov, ntau cov pa luam yeeb dub yuav tawm thaum lub sijhawm nrawm, thiab qhov nrawm yuav yog. qaug zog. Cov qauv sib txawv siv cov tswv yim sib txawv ntawm lub cav. Cov kev ua txhaum tshwj xeeb txawv ntawm cov qauv rau cov qauv.

(1) Thaum lub tshuab hluav taws xob sib sib zog nqus tsis ua haujlwm, lub tshuab hluav taws xob tsis tuaj yeem pib.

(2) Thaum lub tshuab hluav taws xob sib xyaw ua haujlwm tsis ua haujlwm, lub tshuab hluav taws xob tuaj yeem pib thiab khiav ib txwm, tab sis lub cav tsis muaj zog hauv lub zog.

(3) Cov lej txhaum cai feem ntau thaum lub tsheb ciav hlau siab sensor tsis ua haujlwm (poob),

① lub cav tsis tuaj yeem pib thiab khiav: P0192, P0193;

② teeb liab drift, cav torque txwv: P1912, P1192, P1193.
