Infiniti catalytic converter failure

Long term fuel on bank one indicates between 8 and 10 during cruise. Long term fuel on bank 2 is between 7. Does the following indicate a false lean reading and thereby enriching the mixture unnecessarily causing a cat failure?

You're on track. More than likely this is a false lean condition; meaning either unmetered air is entering the intake manifold and ultimately the combustion chambers, or the MAF sensor is not calculating the volume of air entering the engine, correctly. Inspect fuel trim at both idle and while cruising. If short term fuel trim is high during both conditions, suspect a vacuum leak behind or after the throttle plate. It will not hurt to ensure your G35's air fuel ratio sensors are functioning properly either.

The vehicle was taken to an independent mechanic who stated that the driver's side catalytic converter needed to be replaced.

The manufacturer was not contacted. The failure mileage was , After the vehicle was started, the service engine soon warning indicator illuminated. The vehicle was taken to a dealer where it was diagnosed that the catalytic converter needed to be replaced.

The manufacturer was not notified of the failure. The failure mileage was unknown. Engine And Engine Cooling problems. Car Stall problems. Loud Engine Noise problems. Check Engine Light On problems. Engine Belts And Pulleys problems.

Obviously, it is one of the most important parts that fight against the pollution discharged by your Infiniti QX It will transform these harmful gases into water or non-polluting gases.

In order to transform these gases, the catalyst of your Infiniti QX80 a mesh of precious metals which, when the gases pass at high temperature, will break them down by chemical reaction. If you are considering making sufficiently long travels to heat it up regularly count more than 10 kilometres for the catalyst to reach the right temperature , this will enable you to optimise the life of this part and maintain ideal engine effectiveness. We will now discover what can be the outcomes of a dirty or failing catalytic converter on Infiniti QX This will enable you to discover the manifestations that should warn you to a failure of your catalytic converter, here is the list of signs of illness of a faulty catalytic converter:.

Before we accomplish with the step you are almost certainly most curious about, how to clean the catalytic converter of a Infiniti QX80? We will describe why it may be relevant for you to conduct this cleaning. Obviously, a catalytic converter is a very expensive component about euros with the installation, the price can differ according to the engines. Furthermore to being no longer good for passing the technical control , you may be at risk of over-consumption of fuel.

Finally, the last interest is that cleaning a catalytic converter is not that expensive and doing it regularly will save you a lot of money.
