Inzwa yeToyota knock

Qaphela! Vumela injini ukuthi iphole ngokuphelele ngaphambi kokuqala le nqubo.

Ukuthatha umhlalaphansi

1. Inzwa yokungqongqoza ithola ukuqala kokuvutha okunamandla - ukuqhunyiswa kwe-detonation. Lokhu kuvumela injini

ukusebenza ngesikhathi esifanele sokuthungela, okunomthelela omuhle ekusebenzeni kwayo. Lapho injini idlidliza (iqala ukushaya) enjinini, inzwa yokugoqa ikhiqiza i-voltage ephumayo ekhuphuka ngokuqina kokungqongqoza. Le signali ithunyelwa ku-ECM, ebambezela isikhathi sokuvutha kuze kuphele ukuqhunyiswa. Inzwa yokungqongqoza ifakwe ngemuva kwesilinda, ngqo ngaphansi kwekhanda lebhulokhi (eceleni kokuvikela injini).

2. Nqamula ikhebula kutheminali yebhethri enegethivu.

3. Khipha uketshezi ohlelweni lokupholisa (bheka isahluko 1 A).

4. Uma usebenza ngemodeli yangaphambi kuka-2000 4WD noma yangemuva kuka-2001, susa okukodwa kokuningi (bheka isahluko 2A noma 2B). Uma usebenza kumodeli yangaphambi kuka-2000 ngaphandle kwe-2WD, phakamisa ingaphambili lemoto bese ufaka izitendi zojeke.

5. Nqamula isixhumi se-harness bese ususa inzwa yokungqongqoza (bheka i-Fig. 12.5, a, b).

Ilayisi. 12.5 a. Indawo yenzwa yokungqongqoza kumamodeli ngaphambi kokuvulwa kuka-2000

Ilayisi. 12.5b. Knock sensor indawo ngo-2001 ukwethula amamodeli okukhiqiza

6. Uma ufaka kabusha inzwa endala, sebenzisa i-thread sealant emicucu yenzwa. I-sealant isivele isetshenziswe emicu yenzwa entsha; ungasebenzisi i-sealant eyengeziwe, njengoba lokhu kungase kuthinte ukusebenza kwenzwa.

7. Khipha inzwa yokungqongqoza bese uqinisa ngokuphepha (cishe u-41 Nm). Ungayiqinisi kakhulu inzwa ukuze ugweme ukuyonakalisa. Izinyathelo ezisele zenziwa ngohlelo lokuhlehla lokususwa. Per

Gcwalisa uhlelo lokupholisa bese uhlola ukuthi aluvuzi yini.
