P2516 A / C Refrigerant Pressure Sensor B Circuit Range / Hana

Papa Kuhikuhi DTC OBD-II

A / C Refrigerant Pressure Sensor B Circuit Range / Hana

He aha keʻano o kēia?

ʻO kēia kahi code pilikia pilikia diagnostic (DTC) a pili pinepine ʻia i nā kaʻa OBD-II. Pākuʻi paha nā kaʻa kaʻa, akā ʻaʻole kau palena ʻia iā, Chevrolet / Chevy, Ford, Volvo, Dodge, Hyundai, Vauxhall, Honda, Nissan, Renault, Alfa Romeo, etc.

ʻO ka lewa uila (A / C) ʻike kaomi puʻukū hoʻomaʻamaʻa e kōkua i ka ʻōnaehana HVAC (Heating, Ventilation a me Air Conditioning) e hoʻomaʻa i ka mahana i loko o ke kaʻa e kūpono i kāu mau koi.

Mālama ka BCM (Mīkini Mana Kino) a i ʻole ECC (Electronic Climate Control) i ke kiʻikuʻi e hoʻoholo ai i ke kaomi o ka ʻōnaehana a hiki i ka huli ke hoʻohuli i ka compressor ma / like.

ʻO ka mīkini paʻi paʻi A / C kahi transducer puʻe e hoʻololi i ke kaomi i loko o ka ʻōnaehana hōʻoluʻolu i kahi hōʻailona uila analog i hiki ke nānā ʻia e nā modula kaʻa. Hoʻohana ʻia nā kaula 3 maʻamau no kēia: ʻo ka uea kuhikuhi 5V, ka uea hōʻailona, ​​a me ka uea honua. Hoʻohālikelike nā modula i nā koina uea hōʻailona me ka volta kūmole 5V a hiki ke helu koke i ke kaomi ʻōnaehana e pili ana i kēia ʻike.

Huli ka ECM (module mana ʻenekini) i kahi kukui hōʻailona malfunction (MIL) me P2516 a me nā code e pili ana (P2515, P2516, P2517 a me P2518) ke ʻike ʻia kahi hana hewa i ka A / C pahu paʻi paʻi paʻi a i ʻole nā ​​kaapuni. Ma mua o ka hana ʻana i kekahi ʻano diagnostics a me / a i ʻole nā ​​hoʻoponopono hou ʻana ma ka mea hoʻohanohano lewa, e ʻike pono ʻoe i ka nui o nā pilikia e pili ana i ka hana ʻana me ka pahu hau ma lalo o ke kaomi. I ka hapanui o nā hihia, hiki iā ʻoe ke kuhi i kēia ʻano code me ka wehe ʻole o ka ʻōnaehana refrigerator.

ʻO ka Code P2516 A / C cooler pressure sensor B circuit range / ka hana i hoʻonohonoho ʻia ke nānā kekahi o nā modula i ke kiʻiona pressure pressure A / C B me ka hana maʻamau ʻole, kikoʻī ʻole ma kahi o ka pae. ʻO kahi laʻana o kahi mea hoʻohanohano ʻume hoʻoikaika ʻume ea:

He aha ke koʻikoʻi o kēia DTC?

I koʻu manaʻo, haʻahaʻa loa ke koʻikoʻi o nā kuhi pili i ka HVAC. I kēia hihia he pihi hoʻomaʻamaʻa kaomi, ʻo ia paha kahi pilikia e kaomi ana. ʻO wai ka mea e ʻike, hiki i kēia kuhi ke kumu ʻia e ka liu anuanu, a he mea weliweli loa ka liu anuanu, no laila e ʻike pono ʻoe i kahi ʻike maʻamau no ka palekana o ka pahu hau ma mua o ka hoʻāʻo ʻana e hoʻoponopono i ka ʻōnaehana hoʻohanohano ea.

He aha kekahi o nā ʻōuli o ke code?

Pākuʻi ʻia paha nā ʻōuli o ka P2516 diagnostic code:

• Hewa kūpono ʻole o ka lewa mai ka peahi
• Hoʻohana palena ʻia o HVAC
• Kūleʻa ʻole / fluctuating fan ea mahana
• ʻAʻole huli ka compressor A / C ke pono
• ʻAʻole holo pono ka ʻōnaehana HVAC

He aha kekahi o nā kumu maʻamau no ke code?

Nā kumu no kēia P2516 hoʻoili code hiki ke hoʻopili ʻia:

• Kahi hewa a i ʻole hōʻino ʻia ka mīkini ʻenekini hoʻomaʻamaʻa pahu hoʻomaʻemaʻe
• Kūkulu i ka mīkini paʻi puʻuwai A / C
• ʻO ke kiʻekiʻe haʻahaʻa a pololei ʻole paha o ka hoʻoilina
• (Nā) uea pōʻino (wehe, pōkole i +, pōkole i -, etc.)
• Pākuʻi poino
• Ka pilikia me ECC (Electronic Climate Control) a i ʻole BCM (Body Control Module)
• Pili pili ʻole

He aha kekahi mau kaʻina e ʻike pono ai a pilikia i kahi P2516?

Ma mua o ka hoʻomaka ʻana o ke kaʻina hana no ka pilikia, pono ʻoe e loiloi i ka Bulletin Service loea kikoʻī (TSB) e ka makahiki, ka hoʻohālike a me ka lawe ʻana. Mālama kēia kaʻina iā ʻoe i ka manawa a me ke kālā i ka diagnostics a me ka hoʻoponopono ʻana.

Ka anu u kumu # 1

Kaukaʻi ʻia i nā mea hana / ʻike hiki iā ʻoe ke komo, hiki iā ʻoe ke hoʻāʻo maʻalahi i ka hana o nā mīkini ʻūlū hoʻoilina A / C. Hiki ke hana i kēia i nā ala maʻalahi ʻelua: 2. Kaukaʻi ʻia i nā hiki a me nā palena o kāu mea hana OBD / scan scan, hiki iā ʻoe ke nānā i ke kaomi hoʻomaʻemaʻe a me nā waiwai ʻē aʻe i makemake ʻia ke holo nei ka ʻōnaehana e hōʻoia i ka hana pono ʻana o ka sensor. . 1. Inā loaʻa iā ʻoe kahi o nā anana manifold A / C, hiki iā ʻoe ke nānā me ke kaomi me ka hoʻohālikelike ʻana i nā kumukūʻai i makemake ʻia e kāu mea hana.

Manaʻo kōkua: Inā ʻaʻohe ou ʻike me ka coolant, ʻaʻole wau e paipai e luʻu i ka hoʻowalewale hoʻāʻo ʻana, no laila ʻaʻole ʻoe e makemake ma aneʻi, weliweli loa ka coolant no laila ʻaʻohe mea e kolohe ai.

Ka anu u kumu # 2

E hōʻoia i ka mīkini paʻi puʻuwai A / C. E like me kaʻu i ʻōlelo ai ma mua, i ka hapanui o nā hihia he sensor 3-wire pressure kēia sensor. Ke ʻōlelo ʻia nei, e hoʻopili ana ka hoʻāʻo ʻana i ka hoʻāʻo ʻana ma waena o nā pilina a me ka hoʻopaʻa ʻana i kāu mau hopena. ʻO nā koina i makemake ʻia no kēia hoʻāʻo e loli nui e like me ka mea hana, ka mahana, ke ʻano o nā mea ʻike, a pēlā aku, no laila e ʻike pono i kāu ʻike.

OLELO HOOLAHA. E hōʻoia e hoʻohana i nā mākia hōʻoia kūpono me kāu multimeter ke hoʻāʻo nei i nā pin / nā mea hoʻopili. hiki i kahi pin i hōʻino ʻia a i ʻole mea hoʻopili ke kumu i ka intermittent, paʻakikī e ʻike i nā gremlins uila i ka wā e hiki mai ana.

Ka anu u kumu # 3

E hōʻoia uila. I kekahi manawa ua hoʻonohonoho ʻia kēia mau mea ʻike ma ka laina kaomi o ka mea ʻea a kokoke paha i ka pili piping, no laila e hoʻohuli ʻia ke kaula uila e like me ia. Ua ʻike ponoi au i kēia mau mea ʻike ʻino e hōʻino ʻia e ka neʻe ʻana i nā ʻāpana ma lalo o ka pale ma muli o ka paʻa laina pono ʻole. E nānā pono i ka transducer ke nānā pono i ke kino a paʻa pono ka laina.

Nā kūkākūkā DTC e pili ana

• ʻAʻohe kumuhana pili i kēia manawa i kā mākou kolamu. Kau i kahi kumuhana hou ma ke kolamu i kēia manawa.

Pono i kōkua hou me ke code P2516?

Inā makemake ʻoe i kōkua me DTC P2516, kau i kahi nīnau i nā manaʻo ma lalo o kēia ʻatikala.

OLELO HOOLAHA. Hāʻawi ʻia kēia ʻike no ka ʻike wale nō. ʻAʻole ia e manaʻo ʻia e hoʻohana ʻia ma ke ʻano he ʻōlelo hoʻomaikaʻi a ʻaʻole kuleana mākou no kekahi hana āu e hana ai i kekahi kaʻa. Pale ʻia ka ʻike āpau ma kēia pūnaewele e nā kuleana kope.
