Is an 02 oxygen sensor problem related to a catalytic/catalystic converter issue?

Question

Does anyone know if an oxygen sensor problem could be in any way related to an issue with a catalytic/catalystic converter? (spelling?)

Answer 1

If the code is for the #2 O2 sensor ( the one behind the converter) then yes, it is most likely telling you that the 1st O2 Sensor & the 2nd O2 Sensor are giving very similar readings so the catalytic converter is probably not doing much anymore and needs to be replaced.

Good Luck!

Answer 2

Most of the problems are because of the ethanol being added to gasoline.......seems to get worse with older cars.

Answer 3

>>  to an issue with a catalytic/catalystic converter?

What issue?

===

yes the can be related. But they are NOT always related.  The O2 sensor tells the computer to add or subtract more/less fuel. Too much fuel and the Cat converter will over work (get glowing red hot).  But cat converter can also fail on its own.

Good Luck...

Answer 4

To give an answer as simple as your question, Yes, they can be related but not always.
