Kini eyi tumọ si?

Koodu Wahala Aisan (DTC) jẹ koodu gbigbe jeneriki, eyiti o tumọ si pe o kan si awọn ọkọ ti o ni ipese OBD-II ti o ni supercharger tabi turbocharger (Toyota, GMC Chevrolet Duramax, Mazda, Chrysler, Jeep, Ford Powerstroke, bbl).) . Botilẹjẹpe gbogbogbo ni iseda, awọn igbesẹ atunṣe pato le yatọ da lori ami iyasọtọ / awoṣe.

Turbochargers ati superchargers jẹ awọn ifasoke afẹfẹ ti o fi agbara mu afẹfẹ sinu ẹrọ lati mu agbara pọ si. Awọn superchargers ti wa ni ìṣó lati awọn engine crankshaft nipa igbanu, nigba ti turbochargers ti wa ni ìṣó nipasẹ awọn engine eefi gaasi.

Ọpọlọpọ awọn ọkọ ayọkẹlẹ turbocharged igbalode lo ohun ti a pe ni turbocharger geometry oniyipada (VGT). Iru turbocharger yii ni awọn abẹfẹ adijositabulu ni ayika ita ti tobaini ti o le ṣii ati ni pipade lati yi iye titẹ titẹ pọ si. Eyi gba aaye laaye lati ṣakoso turbo ni ominira ti iyara ẹrọ. Awọn ayokele nigbagbogbo ṣii nigbati ẹrọ wa labẹ fifuye ina ati ṣii nigbati fifuye ba pọ si. Ipo abẹfẹlẹ ni iṣakoso nipasẹ module iṣakoso powertrain (PCM), nigbagbogbo nipasẹ iṣakoso ẹrọ itanna solenoid tabi moto. Ipo ti turbocharger jẹ ipinnu nipa lilo sensọ ipo pataki kan.

Lori awọn ọkọ ti o lo turbocharger ti o wa titi ti aṣa ti o wa titi tabi supercharger, igbelaruge ni iṣakoso nipasẹ ibi idalẹnu tabi ibi idalẹnu. Àtọwọdá yii ṣii lati tu titẹ igbelaruge silẹ. PCM ṣe abojuto eto yii pẹlu sensọ titẹ igbelaruge.

Fun DTC yii, “A” tọka iṣoro kan ni ipin kan ti eto eto ati kii ṣe ami aisan kan tabi paati kan.

Koodu P0048 ti ṣeto nigbati PCM n funni ni ifihan agbara iṣakoso didn giga, boya ẹrọ naa nlo turbocharging VGT tabi turbocharger ibile / supercharger.
