Exhaust Manifold Leak Cause Lean Condition at Jennifer Hooper blog

Exhaust Manifold Leak Cause Lean Condition. A leaking exhaust manifold could deceive your vehicle’s oxygen sensors into perceiving that a lean operating condition exists the engine’s. The sensors then notify the engine computer of the perceived lean condition, prompting the computer to turn on the check engine light. This causes a backflow of exhaust gases into the cylinder from the exhaust system. If there was a leak present in the exhaust. A leaking exhaust manifold can significantly impact the overall performance of the vehicle. The exhaust leak will set off a false lean condition, to which the ecu responds by increasing fuel delivery. All it knows is that there is an incorrect ratio of oxygen in the exhaust gases. Consequently, the engine management system will add fuel to burn the oxygen. The disruption in the exhaust gas flow can result in reduced engine power, sluggish. 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.
