P0171 code ka matlab kya hai?
P0171 ka matlab hai ke Bank 1 mein mixture 'lean' hai: hawa zyada aur petrol kam. Engine computer ne petrol barha kar mixture theek karne ki koshish ki, lekin apni had tak pohanch gaya. 4 cylinder engine mein sirf Bank 1 hota hai.
P0171 code kyun aata hai?
- Intake mein hawa ka leak: phati vacuum pipe ya intake gasket.
- Hawa naapne wala MAF sensor maila ya kharab hai.
- Petrol ka pressure kam: kamzor fuel pump ya band fuel filter.
- Injectors maile hain.
- O2 sensor se pehle exhaust mein leak.
P0171 aaye to aap khud kya check kar sakte hain?
- Engine band aur thanda kar ke bonnet ke neeche sirf nazar se dekhein ke koi rubber pipe nikli hui ya phati hui to nahi. Garam engine aur chalte pankhe ko haath na lagayein.
- Air filter dekhein: bohat maila ya mitti se bhara ho to badal dein. Filter ka dabba theek band ho aur us ke clamp kase hue hon.
- Dekhein ke P0174 bhi saath aaya hai ya nahi. Dono saath hon to wajah aksar dono taraf ki ek hi hoti hai, jaise hawa ka leak, MAF sensor ya petrol ka pressure.
Kya P0171 ke saath gaari chalana theek hai?
Agar gaari theek chal rahi hai to aahista chala kar kuch din mein check karwa sakte hain. Lekin lambe arsay tak lean mixture se engine garam ho sakta hai aur misfire shuru ho sakta hai. Jhatke lagein ya light flash kare to fauran mechanic ke paas jayein.
Hifazat: garam engine par radiator ka dhakkan na kholein, khaulta paani nikal kar jala sakta hai. Chalte engine mein pankhe aur belt ke paas haath na le jayein. Petrol ki boo aaye to engine band karein, aag ya sigarette paas na layein aur mechanic bulayein.
Mechanic kab bulayein?
Agar pipe aur air filter theek hain aur code wapas aata hai to car mechanic (mistri) ko dikhayein. Woh smoke test se hawa ka leak aur gauge se petrol ka pressure check karega.
