Output Speed ​​​​Sensor Range / Performance

Ko fault code inorevei P0721?

Dambudziko kodhi P0721 yakajairika OBD-II yekufambisa yekuongorora kodhi inoshanda kune mota dzemhando dzakasiyana siyana uye mhando dzakadai seVW, BMW, Mercedes, Chevrolet, GMC, Allison, Duramax, Dodge, Ram, Ford, Honda, Hyundai, Audi nezvimwe. . Kunyangwe zvakajairika mumasikirwo, matanho ekugadzirisa chaiwo anogona kusiyana zvichienderana negore, kugadzira, modhi uye zvishandiso zvemotokari. Iyo P0721 kodhi ine hukama neiyo transmission output speed sensor uye activation yayo inogona kukonzerwa nekukanganisa kwakasiyana seP0720, P0722 uye P0723, izvo zvinoratidza matambudziko chaiwo.

Chinangwa chekufambisa chinobuda nekumhanyisa sensor ndechekupa ruzivo rwekuburitsa kumhanyisa ruzivo kuPCM (injini yekudzora module). Iyi data inodiwa kudzora shanduko solenoids uye kutarisa giya rekuchinja maitiro, kutapurirana kudzvanywa uye, mune dzimwe nguva, iyo inomhanya.

Pamotokari dzine dhizaini inodzorwa nemagetsi, iyo inobuda yekumhanyisa sensor (OSS) iri kumagumo eiyo shaft yekubuda. Iyo inoyera shaft kutenderera kumhanya, izvo zvakakosha pakuona giya yekuchinja nguva uye torque inoshandura mashandiro.

Kana iyo PCM/ECM yaona kuti iyo OSS sensor haisi kushanda zvakanaka kana kana iri kunze kweyakajairwa mitsara, inogona kuita kuti P0721 kodhi igadzike. Iyi kodhi inoratidza matambudziko anogona kutapurirana uye anogona kukonzera kukanganisa kushanda kweiyo torque inoshandura, nguva yekuchinja, uye mamwe ma paramita.

Zvimwe zvinokonzera

Zvikonzero zveP0721 kodhi zvinosanganisira:

1. Matambudziko ne wiring kana kubatanidza.
2. Iyo yekutapurirana fluid tembiricha sensor yakashata.
