Kedu ihe nke a pụtara?

Nke a bụ Koodu Nsogbu Nsogbu Ịchọpụta Nsogbu (DTC) nke metụtara ọtụtụ ụgbọ ala OBD-II (1996 na nke ọhụrụ). Nke a nwere ike ịgụnye, mana ọnweghị oke na, General Motors, Dodge, Jeep, Chevrolet, Chrysler, Ram, wdg. Ọ bụ ezie na ọnụọgụ, usoro nrụzi kpọmkwem nwere ike ịdịgasị iche dabere na afọ nlereanya, mee, ụdị na nhazi nhazi.

OBD-II DTC P3449 na koodu ndị metụtara P3450, P3451 na P3452 na-ejikọ na sekit # 7 njigide valvụ njigide / njikwa akara.

Ebumnuche nke sekit 7 deactivation / valve valve circuit bụ iji megharịa ọrụ mbibi nke cylinder (dịka ọnọdụ V4 nke injin V8) iji meziwanye akụ na ụba mmanụ ọkụ n'oge arụ ọrụ ọkụ dị ka ịnya ụgbọ ala. Modul njikwa injin (ECM) na -ejikwa ụdị injin cylinder 4 ma ọ bụ 8, gụnyere ịgbanye oriri na -emechi valvụ solenoid maka cylinders anọ nke injin ahụ. Koodu a na -ezo aka na nọmba cylinder 7, na cylinders atọ ndị ọzọ na usoro a na -ekpebi site na nhazi injin na usoro ịgbanye sịlịnda. A na -arụnyere nọmba solenoid deactivation cylinder na ma ọ bụ dị nso na mbata dị nso na cylinder a, dabere n'ụgbọ ala yana nhazi ya.

Mgbe ECM na -achọpụta voltaji ma ọ bụ nguzogide na -adịghị mma na okirikiri njikwa valvụ nke cylinder 7, koodu P3449 ga -edobe na ọkụ njin inyocha, ọkụ ọrụ injin, ma ọ bụ ha abụọ nwere ike gbaa ọkụ n'oge adịghị anya. N'ọnọdụ ụfọdụ, ECM nwere ike gbanyụọ injector # 7 ruo mgbe edoziri nsogbu ahụ wee kpochapụ koodu ahụ, na -ebute ọgbaghara injin na -ahụ anya.
