Crankshaft Sensor: yog vim li cas nws lov thiab yuav ua li cas los hloov nws?

Tej zaum txhua txhua lub tsheb tus neeg txhawb pom nws tus kheej nyob rau hauv ib qhov teeb meem nyob qhov twg muaj ib hnub tom qab tiv cav tseb tseem ceeb tig nws lub "hlau phooj ywg" flatly tsis kam pib. Oddly txaus, tab sis yog vim li cas rau qhov no yuav tsis tau tsuas yog yuav cog los yog hlawv oob khab roj teeb, tab sis lub crankshaft sensor. Yog hais tias nws lub cev twb deformed, los yog tag nrho cov qauv tsiv ob peb millimeters ntawm qhov yuav tsum tau los hloov ib sab. Thiab thaum cov neeg zej zog nyob ib ncig ntawm lub chav nres tsheb koj hais tias cov kev hloov ntawm no lub caij - ib tug es tsis yooj yim ua lag luam, yuav tsum kim tshwj xeeb cov cuab yeej, tsis ntseeg tias cov lus no. Hloov cov crankshaft sensor yuav ua tau rau lawv tus kheej. Ntxiv mus, ua li no hom ntawm kev ua hauj lwm, koj cawm ib tug ntau ntawm cov nyiaj rau cov kev pab noj thiab nyob rau tib lub sij hawm muaj kev nyob rau hauv daim teb no. Yog li ntawd, niaj hnub no tus tsab xov xwm tseem ceeb heev rau tag nrho cov neeg tsav tsheb.

Yog vim li cas crankshaft sensor tsis?

Nyob rau lub hauv paus ntawm indications muab tivthaiv txhaj system synchronizes lub lag luam los ntawm injectors thiab tiv cav tseb. Yog li ntawd, txhaj tshuaj yog tsis tau tsis tau qhov no. Thiab thaum lub crankshaft nres lag luam sensor faults nyob rau hauv ib lub cav pib. Yog li ntawd, tsis muaj leej twg ntawm cov niaj hnub lub tsheb yog ua tsis tiav yam tsis muaj no me ntsis qhov chaw. Nyob rau hauv thiaj li yuav tiv thaiv no tsis ua hauj lwm, koj yuav tsum tsis tu ncua saib qhov mob ntawm lub sensor. Tab sis thaum cov tsos mob pib los ua kev muaj tiag, tus neeg tsav tsheb yog tsis muaj dab tsi lwm tus yuav ua li cas, xws li qhia nws hloov.

Tshem cov crankshaft sensor?

Cia li nco ntsoov tias txoj kev ua no yuav nqa tawm tsis muaj ib tug tshwj xeeb nqa. Tam sim no koj nyob nraum npaj mus. Ua ntej, unscrew lub mounting bolts ntawm lub sensor, uas txuas nrog lub gearbox. Nyob rau hauv qhov tseeb, kom tshem tawm cov cai, peb yuav tsum tau tsuas cov kauj ruam no. Tab sis txij thaum no daim yog muab tso rau hauv ib tug heev tej thaj chaw deb qhov chaw (yuav luag nyob hauv qab), peb yuav muaj ib tug zoo hws. Rau kev ua hauj lwm, peb yuav tsum tau ib tug extension qaum, lub ntsiab yog 11 millimeters, thiab ntawm chav kawm, zoo teeb pom kev zoo. Nws yog ib qho tseem ceeb uas qhov ntev ntawm lub thawj ib feem yog hais txog 80-90 centimeters. Nyob rau hauv lub xub ntiag ntawm cov seev unscrew lub bolts. Tab sis ua ntej tshem cov sensor, crankshaft, them kev mloog kom cov roj hmab hauv ob sab phlu. Yog hais tias nyob rau hauv lub neej yav tom ntej nws yuav tsis zoo ntsia los yog lub clearance yog sib npaug zos rau yam tsawg kawg 1 millimeter, tag nrho cov 'meter' nyeem yog tsis muaj tseeb, thiab raws li, lub cev muaj zog yuav khiav lag luam intermittently. Nws yog qhov zoo tshaj plaws mus kos tus cim no yam khoom thiab teem ib sab nyob rau hauv ib tug nyias muaj nyias ib qhov chaw. Tag nrho cov txheej txheem ntawm dismantling qhov chaw, bolts thiab pawm no ntau npau yuav tsum tau nqa tawm nrog siab ceev faj. Qhov no kom meej tsis nyiam ntxhib tuav.

Tom ntej no, peb coj ib tug tshiab crankshaft sensor thiab nruab nws nyob rau hauv qhov chaw ntawm lub qub. Thaum lub sij hawm installation, lub caij yuav tsum tau nws txo qis los ntawm tag nrho cov cav compartment, thiaj li tsis mus caum rau lub ntsia connector caij los saum toj no. Ces tsis txhob hnov qab txog tso. Mount nws zoo zoo thiab saib kev ncaj ncees ntawm lub tsev. Nws yog ib qho tseem ceeb uas cov kis nruab nrab ntawm nws thiab tus sensor yog tsawg heev los yog tsis tuaj kiag li. Tom qab ntawd, peb muab cov nyob ntawm tej rau qhov uas txuas tag nrho cov terminals thiab pib lub ignition. Yog hais tias koj tau ua txhua yam kom raug, koj yuav tau nco ntsoov - lub engine pib nrog ib tug ib nrab-tig.
