L98- O2 Sensor

If it is faulty, will I get a code? My MPG has gone waaay down in the last couple weeks. Last tank I averaged right around 15 for city driving.

Thanks

Yes, the ecm will set a code if the o2 sensor doesn't show any readings, or if it's out of range. A quick hookup of a scan tool will show you what your o2 sensor is doing. Good luck.

The ECM won't set a code IF the O2 sensor is just simply not working up to par. They're cheap enough though. Replace it if you can't remember the last time that you did. I do it yearly anyways for the heck of it.

Re: (scorp508)

I never have replaced the O2 sensor, so I guess it's time. How much does a sensor run? How much for an O2 sensor socket?

Thanks for the info:cheers:

A 7/8" box end shorty wrench will work just fine instead of a O2 sensor socket. I think I paid Cornwell tools about $22. for the socket tho.

Re: (ittlfly)

The older cars with the single wire O2 sensors are pretty cheap to replace... On my old TPI IROC I paid under $25 for a Bosch replacement at AutoZone...

The older ones were recommended to be replaced around 30K miles from what I remember... They do tend to get lazy/slow with age or if you've ever had any A/F problems such as with a MAF going out...

Also they load up with carbon especially if you don't drive it hard or make lots of short trips...

I've replaced my O2s a couple of times on different cars and they always ran better/more effieiently afterward...

It's a good idea and it's cheap...

I can't say for sure on the Vette, but on my old IROC I didn't need an O2 socket to remove/replace it...
