Can A Exhaust Leak Cause A P0171 at Janine Hall blog

Can A Exhaust Leak Cause A P0171. This can be caused by something like a disconnected hose or vacuum leak, which means there’s more air than usual, or because your fuel. There are multiple possible reasons for a p0171 code to arise. • weak fuel pump— if the fuel. How to diagnose the cause of your p0171 code. An exhaust leak upstream of the o2 is kind of unlikely to cause a p0171, as it would have to be siphoning 'clean' air in via venturi. • exhaust leak— any leak that occurs ahead of the upstream oxygen sensor will let too much outside air into the exhaust, causing this code. Common causes include faulty oxygen sensor, mass airflow sensor, pcv system leaks, vacuum leaks, bad air filter, clogged fuel filter, faulty fuel injectors, and exhaust leaks. When this code pops up, it indicates that the engine is running too lean or with an air/fuel mixture that contains too much air and not enough fuel. Trouble spots can include a vacuum leak, faulty mass air flow sensors, clogged fuel injectors, or issues with an oxygen sensor or fuel pressure regulator.
