P0172System Too Rich (Bank 1)

The engine computer detected that the air-fuel mixture on bank 1 is too rich, meaning there is too much fuel or not enough air. The computer reduced fuel as much as it could but still measured an over-rich mixture. Running rich wastes fuel and can foul spark plugs and damage the catalytic converter.

ყველაზე გავრცელებული მიზეზებია: Dirty or faulty mass air flow (MAF) sensor, Leaking or stuck-open fuel injectors, High fuel pressure (faulty fuel pressure regulator), Faulty oxygen sensor, Dirty air filter or restricted air intake, Faulty engine coolant temperature sensor (false cold reading).

ჩვეულებრივ უსაფრთხოა მცირე მანძილზე მგზავრობა, მაგრამ მალე გადაამოწმებინეთ.

Have a professional read live fuel trim data and inspect the MAF sensor and air filter, since metering and intake restrictions are common causes. They should also check fuel pressure and the injectors for leaks; it is generally drivable, but fix it soon because a rich mixture can foul plugs and harm the catalytic converter.
