Pehea e nānā ai i kahi sensor PMH?
Nā mea
Pūnaewele Kikowaena make make (TDC) o kāu kaʻa e hoʻoholo i ke kūlana pistons... A laila e hoʻouna i kēia ʻike i ka mīkini ECU, a laila hiki ke hoʻoholo i ka hoʻokele wahie e pono ai no ka wikiwiki. Inā he hemahema ka ʻike TDC, loaʻa iā ʻoe pilikia hoʻomaka... Eia pehea e nānā ai i kahi sensor PMH.
Pono Pono:
- Ke komo ʻana
- Paʻi
- Nā Mea Hana
- Voltmeter
- oscilloscope
- Multimeter
🔎 KaʻAnuʻu 1: E nānā maka i ka mea ʻike TDC.
No ka hoʻāʻo ʻana i ka sensor TDC, pono ʻoe e komo mua iā ia. ʻO ka mea ʻike TDC, i kapa ʻia ʻo ka crankshaft sensor, aia ma ka crankshaft a me ka lele lele ma lalo o ka mīkini. Wehe i ka wili hoʻopaʻa ʻike a wehe i ke kaula ma waena o ka mea ʻike TDC a me ka ECU mīkini.
E hoʻomaka kākou me kahi nānā ʻike maʻalahi o ka sensor TDC:
- E hōʻoia ʻaʻole i paʻa;
- E hōʻoia i ka pōʻino o ka ea;
- E nānā i ke kāʻei ma waena o TDC sensor a me ka mīkini ECU.
Hiki iā ʻoe ke lawe i ka manawa kūpono e nānā i ka sensor PMH me ka hoʻohana ʻana i kahi panana. He ʻano hōʻike mua liʻiliʻi, hiki iā ia ke haʻi iā ʻoe inā e hana ana ka sensor. ʻOiaʻiʻo, loaʻa i kahi sensor TDC inductive kahi māla magnetic e ʻike i nā mea metala.
- Inā huki ka mea ʻike i ka ʻākau, hana ia;
- Inā huki ʻo ia i ka hema, ʻo ia ʻo HS!
'Ōlelo, ʻaʻole hana kēia hoʻāʻo me kahi mea ʻike PHM ikaika, ʻike ʻia hoʻi he hopena Hall. ʻAʻohe kahua electromagnetic ka mea ʻike TDC ikaika no ka mea he uila holoʻokoʻa. Loaʻa ia, ʻo ia hoʻi, ma nā ʻenekini hou loa.
💧 KaʻAnuʻu 2. E hoʻomaʻemaʻe i ka sensor TDC.
No ka hana piha, ʻaʻole pono e hoʻohaumia ka mea ʻike TDC. Eia pehea e hoʻomaʻemaʻe ai i ka sensor TDC ma mua o ka nānā ʻana.
- E kāpīpī i ka WD 40 a i ʻole ka momona ʻē aʻe ma ke kino ʻike;
- E holoi mālie me ka lole maʻemaʻe a pau ka lepo a me ka ʻōpala.
⚡ KaʻAnuʻu 3. E nānā i ka hōʻailona uila a me ke kū'ē o ka mea ʻike TDC.
A laila e nānā ʻoe i ka hōʻailona uila a me ke kūpaʻa o kāu sensor TDC. Eia naʻe, e makaʻala i ke ʻano o ka mea ʻike i nīnau ʻia: inā loaʻa iā ʻoe kahi sensor TDC ikaika, ʻaʻohe ou kūʻē i ka hoʻāʻo. Hiki iā ʻoe ke nānā i ka hōʻailona mai ka Hall effect TDC sensor.
E hoʻohana i ka ohmmeter a i ʻole multimeter e nānā i ka mea ʻike TDC inductive. E hoʻohui i kahi multimeter i ka puka o ka TDC sensor a nānā i ka waiwai i hōʻike ʻia. Pili ia i ka mea hana kaʻa. I kekahi hihia, aia ma waena o 250 a me 1000 ohms. Inā ʻaʻole ia, aia kahi kaapuni pōkole ma kahi.
A laila e nānā i ka hōʻailona uila. E hoʻohana i kahi oscilloscope e hoʻāʻo ai i kahi mea ʻike Hall effect TDC nona nā uea 3 (maikaʻi, ʻino a me ka hōʻailona). Ua ʻike ʻia he rectangular. No ka mea ike TDC hana, he sinusoidal ka oscilloscope.
E nānā i ka hōʻailona puka me ka voltmeter. E hoʻokaʻawale i ka mea hoʻohui ʻike TDC a hoʻohui i kahi voltmeter i ka puka AC. ʻO ka hopena o kahi sensor TDC maikaʻi ma waena o 250 mV a me 1 Volt.
👨🔧 KaʻAnuʻu 4. Holo i nā diagnostics uila.
Eia naʻe, ʻaʻole i loaʻa i nā mea a pau ke ala hilinaʻi a hilinaʻi hoʻi e nānā i ka sensor TDC, nā diagnostics uila. ʻOiaʻiʻo, a laila pono ʻoe i kahi hihia diagnostic a me ka polokalamu autodiagnostic e pili pū ana. Eia nō naʻe, ʻoi aku ka pipiʻi o kēia hāmeʻa a ʻo ka mea maʻamau wale nō ka mea nona nā mechanics ʻoihana. Akā inā he mechanic ʻoe, ʻaʻohe mea e kāohi iā ʻoe mai ka hoʻopukapuka kālā.
Hoʻihoʻi ka polokalamu diagnostic i kahi kuhi hewa e hōʻike ana i ke ʻano o ka pilikia me ka sensor TDC (no ka laʻana, ʻaʻohe hōʻailona). Hiki iā ʻoe ke holo i nā diagnostics i ka hoʻomaka ʻana e nānā, me kahi pihi mālama ʻia, ka hana pololei o ka sensor.
🔧 KaʻAnuʻu 5: E hōʻuluʻulu i ka sensor TDC
Ma hope o ka nānā ʻana i ka sensor TDC, pono ʻoe e hui hou iā ia. E hoʻouka i ka mea ʻike palahalaha, e hoʻopaʻa i ka wili hoʻoponopono. Hoʻopili hou i ke kaula ʻike, a laila hoʻomaka i ke kaʻa e hōʻoia i ka hana pono.
ʻO ia, ʻike ʻoe pehea e hoʻāʻo ai i kahi sensor PMH! Akā, e like me kāu i hoʻomaopopo mua ai, ʻo ka hoʻāʻo maikaʻi loa ʻo ia ka diagnostics uila, nā code e ʻae iā ʻoe e ʻike i ke ʻano o ka pilikia. E nānā a hoʻololi i ka sensor PMHno laila e hoʻohālikelike i nā hale kaʻa a puni a hāʻawi i kāu kaʻa i nā mea maikaʻi!
