Can A Exhaust Leak Cause A Lean Code at Lula Atchley blog

Can A Exhaust Leak Cause A Lean Code. When an exhaust leak is present, the ecu can detect a false lean signal and respond incorrectly, adding fuel in an attempt to remedy the problem, but further exacerbate. Yes, if you have a lean code on 1 bank, it rules out things common to both banks. Exhaust leaks can cause o2 sensors to read lean. An exhaust leak ahead of the catalytic converter is the second most common cause of this code. Exhaust leaks are a common cause of p0174 trouble codes. An exhaust leak can definitely cause rough idle if the leak is located before the upstream o2 sensor or very close to it. If there was a leak present in the exhaust before the front o2 sensor then fresh air is sucked in and the o2 content of the exhaust. There are also some other. The exhaust leak will set off a false lean condition, to which. So if you have those codes and a know exhaust leak, fix the exhaust leak, clear the codes, and see if they come back. That rules out maf and fuel. High (o2) content in the exhaust, equals a lean reading, also causing engine misfires.
