Iyini umehluko phakathi kwe-evap leak detection pump ne-vent valve?
Zombili zibalulekile ekutholeni ukuvuza. I-vent valve ivumela umoya omusha kodwa ivala ngesikhathi sokuhlola. I-leak detection pump icindezela uhlelo ukuze ithole ukuvuza.
Uma ingakwazi ukugcina ingcindezi, izokhombisa isexwayiso ku-dashboard.
Yini ama-codes e-evap ajwayelekile afana no-P0442 no-P0456 akhombisa?
Lezi zikhodi zisho ukuthi kukhona uku leak ohlelweni. P0442 iyakha uku leak okuphakathi, kanti P0456 iyakha uku leak okuncane. Njalo, ukulungisa lokhu kulula, njengokushintsha ikhava ye-gas noma ukuqinisa umugqa.
Ingabe ukuhlole i-evap kuyinto esingayiphatha ekhaya?
Yebo, singakwazi ukwenza ukuhlole okuyisisekelo ekhaya. Bheka i-valve ye-evap purge kanye nezintambo kumsensor we-pressure ye-tank ye-fuel. Kodwa, ukuze uthole uku leak okukhanyayo, kungase kudingeke ukuhlolwa okwenziwa ochwepheshe.
Ingabe singaqhubeka sishayela imoto yethu uma kukhona inkinga ohlelweni lwe-evap?
Uhlelo lwe-evap olubi lungakushiya ungakaze uhambe. Kodwa, kungcono ukukulungisa ngokushesha. I-canister engalungile noma ipompo ingalimaza umnotho we-fuel futhi ibangele ukuphumelela kokuhlolwa kokukhishwa.
Ukukulungisa ngokushesha kuhle kwemvelo kanye nokusebenza kwemoto yakho.
