Is My O2 Sensor Bad Or Catalytic Converter
Is My O2 Sensor Bad Or Catalytic Converter. You should be looking at the o2 sensor on the exhaust on the bank that does not have the #1 cylinder. There is no need to worry about the sensors in the downstream or diagnostic areas monitoring the exhaust leaving the catalytic converter.
Other engine problems, such as fuel trim running too rich or too lean, oil or coolant burning, or engine misfire problems could all lead to catalytic converter contamination or premature failure. P0430 is a bank 2 code. You should be looking at the o2 sensor on the exhaust on the bank that does not have the #1 cylinder.
In Addition To A Rough Idle, A Misfire, And/Or Hesitation When Trying To Accelerate, A Bad Oxygen Sensor May Also Have.
However, this light can indicate a number of mishaps that are not the only symptoms to look for to diagnose a sensor and converter issue. The oxygen sensor measures oxygen levels in the exhaust. They get too hot, melt and plug up, or the catalyst becomes contaminated and useless.
The Problem Is That If Your Rear O2 Sensor Is Not Working, You Are Never Going To Know For Sure If Your Catalytic Converter Is Working Properly Unless A Rotten Egg Or Sulfurous Smell Starts Coming Out Of Your Exhaust Tip.
However, if either of the o2 sensors are lagging in displaying the wave patterns, then it could be them. Also, the information recorded by downstream sensors is sent to the ecu for further processing. The mechanic told me to replace both o2 sensors to resolve the fault code but after seeing the o2 sensor readings doesnt this indicate i have a bad catalytic converter?
Although Do Keep In Mind That It Is Also Possible For The Muffler To Be Clogged If Your Catalytic Converter Got So Bad That Parts Of The Debris Flew Out Into The Muffler.
Other engine problems, such as fuel trim running too rich or too lean, oil or coolant burning, or engine misfire problems could all lead to catalytic converter contamination or premature failure. Yes, the oxygen sensor can damage the catalytic converter, although the damage is indirect. Take note that i had a long time bad intake manifold leak and radiator leak leading to an overheated engine and some crazy hot / cold blowing from the in cabin blower.
Will Removing A Catalytic Converter Cause A Check Engine Light?
An exhaust leak near the upstream sensor can cause the downstream sensor to read a steady lean condition. Here’s where you could have an o2 sensor related p0420. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a dtc for itself.
Is My Car's New Catalytic Converter Bad Or Could It Be That The O2 Sensors Need To Be Changed?
The ecm would interpret that as a bad catalytic converter. Bad smell coming out from the exhaust. I think there’s some other underlying problem here.
