Ua tib zoo mloog cov ntsiab lus hauv qab no hauv ECU kuaj:

① Tig lub qhov hluav taws xob hluav taws xob: tshem tawm ECU ntsaws.② Qhib lub qhov hluav taws xob hloov hluav taws xob: siv lub tshuab hluav taws xob los kuaj xyuas lub zog ntawm ECU.Qhov hluav taws xob nruab nrab ntawm tus pins 2 thiab 3 ntawm ECU ntsaws thiab qhov hluav taws xob ntawm tus pins 1 thiab 2 yuav tsum tsis txhob tsawg dua 11V, txwv tsis pub, kos lub voj voog.

2) Kev kuaj xyuas qhov ntsuas kub ntawm qhov ntsuas cua txias ① Kev kuaj kab hluav taws xob: tua hluav taws xob hloov hluav taws xob thiab tshem tawm 4 lub qhov ntsaws ntawm lub ntsuas cua txias, raws li pom hauv daim duab 2-36.Xyuas seb puas muaj ib qho qhib Circuit Court nyob rau hauv cov hlau nyob nruab nrab ntawm 3rd qhov ntawm 4-qhov ntsaws ntawm lub coolant kub sensor thiab 53rd qhov ntawm lub ECU socket (qhov tsis kam ntawm cov hlau yuav tsum tsis txhob ntau tshaj 1.5Ω), thiab seb puas cov hlau yog luv luv-circuited rau tus ncej zoo ntawm lub hwj chim mov (qhov kev tiv thaiv yuav tsum yog infinite).Xyuas seb puas muaj qhov qhib Circuit Court nyob rau hauv cov hlau lead ntawm thawj lub qhov ntawm 4-qhov ntsaws ntawm lub coolant kub sensor thiab lub 67th qhov ntawm lub ECU socket (cov hlau lead kuj yuav tsum tsis txhob ntau tshaj 1.5Ω).② Kev soj ntsuam kev ua tau zoo: tua lub qhov hluav taws xob hloov hluav taws xob, tshem tawm qhov ntsuas kub ntawm qhov ntsuas kub, muab lub ntsuas cua txias rau hauv lub khob dej, thiab siv lub ntsuas ntsuas ntsuas ntsuas qhov ntsuas qhov ntsuas ntawm tus pins 1 thiab 3 ntawm lub ntsuas cua txias.Cov txiaj ntsig sib xws ntawm cov dej kub thiab kev tiv thaiv yuav tsum ua tau raws li qhov tseem ceeb qhia hauv Table 2-19.Table 2-19 Cov Table Kub Kub thiab Kev Ua Haujlwm ntawm Coolant Temperature Sensor

3) Ua tib zoo mloog cov ntsiab lus hauv qab no thaum kuaj pom lub crankshaft txoj hauj lwm sensor (lub cav ceev sensor): ① Tig lub ignition hloov: tshem tawm dawb 3-qhov ntsaws ntawm lub crankshaft txoj hauj lwm sensor (cav ceev sensor).② Tshawb xyuas qhov kev tiv thaiv ntawm cov ntsaws: Raws li pom hauv daim duab 2-37, qhov kev tawm tsam ntawm qhov 1 thiab 3 (hauv av) thiab ntawm qhov 2 thiab 3 (hauv av) yuav tsum tsis muaj qhov kawg.Txheeb xyuas qhov tsis kam ntawm tus pin 1 thiab tus pin 2 ntawm lub sensor, uas yuav tsum yog 450 ~ 1000 Ω.Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov ntaub ntawv txuas ntxiv feem ntau tso tawm cov teeb liab mem tes (kwv yees sine yoj lossis lub voj voos).Cov txheej txheem rau kev ntsuas qhov kev sib hloov ceev ntawm cov teeb liab mem tes suav nrog: kev sib koom ua ke zaus (uas yog, F / V hloov pauv txoj kev, nws qhov txiaj ntsig ncaj qha yog qhov hluav taws xob lossis tam sim no) thiab txoj kev ua haujlwm zaus (uas yog cov txiaj ntsig ncaj qha yog digital).

Nyob rau hauv automation technology, muaj ntau yam kev ntsuas ntawm kev sib hloov ceev, thiab cov linear ceev feem ntau indirectly ntsuas los ntawm rotational ceev.DC tachogenerator tuaj yeem hloov qhov nrawm nrawm rau hauv lub teeb liab hluav taws xob.Lub tachometer yuav tsum muaj kev sib raug zoo ntawm cov zis hluav taws xob thiab kev sib hloov ceev, thiab yuav tsum muaj qhov tso zis hluav taws xob kom nruj thiab lub sijhawm thiab qhov kub thiab txias kom zoo.Lub tachometer feem ntau tuaj yeem muab faib ua ob hom: DC hom thiab AC hom.Lub rotary ceev sensor yog nyob rau hauv kev sib cuag nrog cov khoom txav.Thaum ib qho khoom txav tau nyob rau hauv kev sib cuag nrog lub teb ceev sensor, kev sib txhuam tsav cov menyuam ntawm lub sensor tig.Lub rotating mem tes sensor mounted rau cov menyuam xa tawm ib tug series ntawm pulses.Txhua tus mem tes sawv cev rau qee qhov kev ncua deb, kom cov kab nrawm tuaj yeem ntsuas tau.Electromagnetic induction hom, ib lub iav yog ntsia rau ntawm lub rotating ncej, thiab sab sab yog ib tug electromagnetic kauj.Kev sib hloov yog vim qhov sib txawv ntawm cov hniav ntawm cov iav, thiab cov square yoj hloov voltage tau txais, thiab ces qhov kev sib hloov ceev yog xam.Lub rotary ceev sensor tsis muaj kev sib cuag ncaj qha nrog cov khoom txav, thiab cov yeeb yaj kiab uas muaj qhov cuam tshuam tau txuas mus rau cov hniav ntug ntawm lub impeller.Thaum cov kua ntws tawm, nws tsav lub impeller tig, thiab cov fiber ntau optical xa cov teeb pom kev zoo ib zaug txhua qhov kev sib hloov ntawm lub impeller los tsim cov teeb liab hluav taws xob.Qhov ceev tuaj yeem xam los ntawm tus naj npawb ntawm cov pulses pom.
