P0099 IAT Sensor 2 Dera Labwino

P0099 IAT Sensor 2 Dera Labwino

Mapepala a OBD-II DTC

Wambiri Kutentha kwa mpweya SENSOR 2 Dera Kulephera

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yofalitsira, zomwe zikutanthauza kuti imagwira ntchito pagalimoto zonse kuyambira 1996 (Ford, Mazda, Mercedes Benz, etc.). Ngakhale ndizachilengedwe, njira zowongolera zimatha kusiyanasiyana kutengera mtundu / mtundu.

Khodi yosungidwa P0099 imatanthawuza kuti gawo loyendetsa mphamvu yamagetsi (PCM) lazindikira zolowetsa mkati kuchokera # 2 intake air kutentha (IAT) sensor dera.

PCM imagwiritsa ntchito kulowetsa kwa IAT komanso kulowetsa masensa mpweya (MAF) kuwerengera kuperekera mafuta ndi nthawi yoyatsira. Popeza kukhalabe ndi mpweya / mafuta oyenera (makamaka 14: 1) ndikofunikira pakuwongolera kwa injini ndi mafuta, kulowetsa kwa IAT ndikofunikira.

Chojambulira cha IAT chimatha kuzunguliridwa ndikulowetsa kangapo, koma nthawi zambiri chimalowetsedwa m'bokosi lochulukitsa kapena loyeretsera mpweya. Opanga ena amaphatikizanso sensa ya IAT munyumba ya MAF sensor. Mulimonsemo, iyenera kukhazikitsidwa kotero kuti (ndi injini ikuyenda) mpweya wozungulira womwe umalowetsedwa munthawi zambiri kudzera mthupi loyenda umatha kupitilira mosadukiza.

Chojambulira cha IAT nthawi zambiri chimakhala ndi ma waya awiri a thermistor sensor. Kukaniza kwa sensa kumasintha kutengera kutentha kwa mpweya wodutsa pama waya ozizira. Magalimoto ambiri a OBD II amagwiritsa ntchito voliyumu yama volti (ma volts asanu ndi abwinobwino) ndi siginecha yapansi kutseka dera la sensa ya IAT. Magulu osiyanasiyana olimbirana mu IAT sensing element amachititsa kusinthasintha kwamagetsi mdera lolowera. Kusintha uku kumatanthauziridwa ndi PCM monga kusintha kwa kutentha kwa mpweya.

PCM ikazindikira manambala angapo apakatikati pa kachipangizo ka IAT # 2 munthawi inayake, nambala ya P0099 idzasungidwa ndipo nyali yowunikira ikhoza kuwunikira.

Kulimba ndi zizindikilo

Chizindikiro chochokera ku sensa ya IAT chimagwiritsidwa ntchito ndi PCM kuwerengera njira yamafuta, chifukwa chake nambala ya P0099 iyenera kuonedwa ngati yayikulu.

Zizindikiro za chikhombo cha P0099 zitha kuphatikizira izi:

• Kuchepetsa mafuta pang'ono
• Kuchepetsa magwiridwe antchito a injini (makamaka pakuyamba kuzizira)
• Kuzengereza kapena kuthamanga mopanda kanthu kapena pang'onopang'ono
• Ma code ena olamulira akhoza kusungidwa

zifukwa

Zomwe zingayambitse kachidindo kameneka ndi monga:

• Tsegulani kapena zazifupi zazingwe ndi / kapena zolumikizira za IAT No. 2 sensor
• Chotupa cholowera kutentha kwa mpweya # 2.
• Opunduka misa mpweya otaya sensa
• Fyuluta yampweya
• Kuphulika kwa chitoliro cholowera mpweya

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Ndikakumana ndi kachilombo ka P0099, ndimakonda kukhala ndi sikani yoyesera, digito volt / ohmmeter (DVOM), infrared thermometer, komanso gwero lodalirika lazidziwitso zamagalimoto (monga All Data DIY) omwe ndili nawo.

Lumikizani chojambulira pazitsulo zamagalimoto ndikutenga ma DTCs osungidwa ndi chimango chofanana. Nthawi zambiri ndimalemba izi kuti mwina ndidzafunika mtsogolo. Chotsani ma code ndikuyesa kuyendetsa galimotoyo. Ngati nambala yanu ithe nthawi yomweyo, pitirizani kuwunika.

Akatswiri ambiri amayamba ndikuwunika mawaya ndi zolumikizira zogwirizana ndi sensa ya IAT (osayiwala fyuluta ya mpweya ndi chitoliro cholowera mpweya). Samalani kwambiri chojambulira cha sensa chifukwa chitha kuwonongeka chifukwa chakuyandikira kwa batire ndi malo ozizira.

Ngati makina olumikizira, zolumikizira ndi zida zake zikugwira ntchito, lumikizani chojambulira ndi chojambulira cha matenda ndikutsegula tsambalo. Mukamachepetsa kutsata kwanu kuti mukhale ndi zofunikira zokha, mudzayankhidwa mwachangu. Gwiritsani ntchito thermometer ya infrared kuti muwonetsetse kuti kuwerenga kwa IAT (pa sikani) kumawonetsa bwino kutentha kwa mpweya.

Ngati sichoncho, funsani gwero lazidziwitso zamagalimoto anu kuti mupeze upangiri pakuyesa kwa sensa ya IAT. Gwiritsani ntchito DVOM kuti muyese sensa ndikuyerekeza zotsatira zanu ndizofotokozera zagalimoto. Sinthani sensa ngati sichikwaniritsa zofunikira.

Ngati sensa ikadutsa mayeso oyeserera, yang'anani zamagetsi zamagetsi ndi nthaka. Ngati wina akusowa, konzani zotseguka kapena zazifupi mdera ndikuyesanso makinawo. Ngati zikwangwani zadongosolo ndi zikwangwani zapansi zilipo, pezani chithunzi cha mpweya wamagetsi ndi kutentha kwa IAT kuchokera pagwero lazidziwitso zamagalimoto ndipo mugwiritse ntchito DVOM kuti muwone mphamvu yotulutsa sensa. Yerekezerani magetsi ndi magetsi motsutsana ndi chithunzi cha kutentha ndikusintha sensa ngati zotsatira zenizeni zikusiyana ndi kulolerana kokwanira.

Ngati magetsi enieni a IAT ali mkati mwazinthu, chotsani zolumikizira zamagetsi kuchokera kwa owongolera onse ogwiritsira ntchito ndipo mugwiritse ntchito DVOM kuyesa kukana ndikupitilira pama circuits onse m'dongosolo. Konzani kapena sinthani ma circuits aliwonse otseguka kapena afupipafupi ndikuyesanso makinawa.

Ngati sensa ya IAT ndi ma circuits onse azinthu zili mkati mwazomwe zikulimbikitsidwa, ganizirani zolakwika za PCM kapena PCM zolakwika.

Zowonjezera zowonjezera:

• Chifukwa chodziwika kwambiri chosungira P0099 ndicholumikizira cholumikizira # 2 IAT cholumikizidwa. Fyuluta ya mpweya ikafufuzidwa kapena kusinthidwa, sensa ya IAT nthawi zambiri imakhala yolumala. Ngati galimoto yanu yatumizidwa posachedwa ndipo nambala ya P0099 yasungidwa mwadzidzidzi, ganizirani kuti sensa ya IAT siyimasulidwa.

Associated Sensor ndi IAT Dera DTCs: P0095, P0096, P0097, P0098, P0110, P0111, P0112, P0113, P0114, P0127

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi nambala yanu ya p0099?

Ngati mukufunabe thandizo ndi DTC P0099, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
