Yuav kuaj PMH sensor li cas?
Txheem
Sensor Sab saum toj tuag center (TDC) ntawm koj lub tsheb txiav txim txoj haujlwm pistons... Nws mam li xa cov ntaub ntawv no mus rau lub cav ECU, uas tuaj yeem txiav txim siab cov roj txhaj tshuaj uas yuav tsum tau ua kom nrawm. Yog tias TDC sensor tsis raug, koj yuav muaj teeb meem pib... Nov yog yuav kuaj PMH sensor li cas.
Khoom siv:
- Nkag mus
- Chiffon
- Cov cuab yeej
- Voltmeter
- oscilloscope
- Ntau yam
🔎 Kauj Ruam 1: Saib xyuas TDC sensor.
Txhawm rau kuaj TDC sensor, koj yuav tsum xub nkag mus rau nws. Lub TDC sensor, tseem hu ua crankshaft sensor, nyob ntawm lub crankshaft thiab flywheel nyob rau hauv qab ntawm lub cav. Tshem lub sensor tuav cov ntsia hlau thiab txiav lub hlua khi ntawm TDC sensor thiab lub cav ECU.
Cia peb pib nrog kev kuaj pom yooj yim ntawm TDC sensor:
- Xyuas kom nws tsis txhaws;
- Xyuas kom qhov sib txawv ntawm huab cua tsis puas;
- Txheeb xyuas cov hlua khi ntawm TDC sensor thiab lub cav ECU.
Koj tuaj yeem siv sijhawm los txheeb xyuas PMH sensor siv lub compass. Nws yog hom kev sim ua ntej me ntsis, nws tuaj yeem qhia koj yog tias lub sensor ua haujlwm. Tseeb, ib qho inductive TDC sensor muaj qhov sib nqus teb uas pom cov khoom hlau.
- Yog hais tias lub sensor yog rub sab qaum teb, nws ua haujlwm;
- Yog nws kos sab qab teb, nws yog HS!
Kev ceeb toom, qhov kev sim no tsis ua haujlwm nrog PHM sensor, tseem hu ua Hall effect. Lub active TDC sensor tsis muaj electromagnetic teb vim nws yog hluav taws xob kiag li. Nws pom, tshwj xeeb tshaj yog nyob rau hauv cov cav tov tsis ntev los no.
💧 Kauj Ruam 2. Ntxuav lub TDC sensor.
Rau kev ua haujlwm tag nrho, TDC sensor yuav tsum tsis txhob muaj kab mob. Nov yog yuav ua li cas ntxuav TDC sensor ua ntej kuaj nws:
- Txau WD 40 lossis lwm yam roj rau ntawm lub cev sensor;
- So kom huv si nrog ib daim ntaub huv kom txog thaum tag nrho cov av thiab xeb tshem tawm.
⚡ Kauj Ruam 3. Txheeb xyuas cov teeb liab hluav taws xob thiab qhov tsis kam ntawm TDC sensor.
Tom qab ntawd koj yuav tshuaj xyuas cov teeb liab hluav taws xob thiab kev tiv thaiv ntawm koj TDC sensor. Txawm li cas los xij, ceev faj nrog hom sensor hauv nqe lus nug: yog tias koj muaj lub zog TDC sensor, koj tsis muaj kev tiv thaiv. Koj tsuas tuaj yeem tshawb xyuas lub teeb liab los ntawm Hall effect TDC sensor.
Siv lub ohmmeter los yog multimeter los xyuas qhov inductive TDC sensor. Txuas lub multimeter mus rau qhov tso zis ntawm TDC sensor thiab xyuas cov nqi tso tawm. Nws nyob ntawm tus tsim tsheb. Txawm li cas los xij, nws yuav nyob nruab nrab ntawm 250 thiab 1000 ohms. Yog tias nws yog xoom, muaj qhov luv luv ntawm qhov chaw.
Tom qab ntawd xyuas cov teeb liab hluav taws xob. Siv lub oscilloscope los ntsuas Hall effect TDC sensor uas muaj 3 xov hlau (zoo, tsis zoo thiab teeb liab). Nws hloov tawm mus ua lub duab plaub. Rau lub active TDC sensor, lub oscilloscope yog sinusoidal.
Txheeb xyuas cov teeb liab tso zis nrog lub voltmeter. Tshem tawm TDC sensor connector thiab txuas ib lub voltmeter rau AC qhov hluav taws xob. Qhov tshwm sim ntawm qhov zoo TDC sensor yog nruab nrab ntawm 250 mV thiab 1 Volt.
👨🔧 Kauj Ruam 4. Khiav electronic diagnostics.
Txawm li cas los xij, txoj kev txhim khu kev qha thiab txhim khu kev qha tshaj plaws los xyuas TDC sensor, kev kuaj hluav taws xob, tsis muaj rau txhua tus. Qhov tseeb, tom qab ntawd koj yuav tsum muaj cov ntaub ntawv kuaj mob thiab cov software autodiagnostic nrog. Txawm li cas los xij, cov cuab yeej no kim heev thiab feem ntau tsuas yog muaj los ntawm cov kws kho tsheb. Tab sis yog tias koj yog tus kws kho tsheb, tsis muaj dab tsi txwv koj ntawm kev nqis peev.
Cov software kuaj mob rov qab ua qhov yuam kev uas qhia txog qhov xwm txheej ntawm qhov teeb meem nrog TDC sensor (piv txwv li, tsis muaj teeb liab). Koj tseem tuaj yeem khiav kev kuaj mob thaum pib los soj ntsuam, nrog kev tswj xyuas nkhaus, ua haujlwm raug ntawm lub sensor.
🔧 Kauj Ruam 5: Sib dhos TDC sensor
Tom qab kuaj xyuas TDC sensor, koj yuav tsum rov ua dua. Txhim kho lub sensor tiaj tus, zawm cov ntsia hlau kho. Reconnect lub sensor hlua, ces pib lub tsheb kom paub tseeb tias nws ua hauj lwm zoo.
Qhov ntawd yog nws, koj paub yuav ua li cas kuaj PMH sensor! Tab sis, raws li koj twb tau nkag siab lawm, qhov kev xeem zoo tshaj plaws tseem yog kev kuaj hluav taws xob, cov lej uas tso cai rau koj kom paub tseeb tias qhov teeb meem yog dab tsi. Mus xyuas thiab hloov PMH sensorYog li sib piv cov chaw nres tsheb nyob ib puag ncig thiab tso siab rau koj lub tsheb mus rau qhov zoo!
