Hi,
i thinks my 02 sensor is faulty as its started when ive a loosen silicon hose while driving on the hway and my afr immediately drop pig rich.
After i fixed the clips, my afr reading on my aem digital gauge shows irregular afr reading from rich to super lean til no reading and the gauge kept blinking.

Is it time for replacement as ive just bought the aem wb set about 4 months ago.

Just wonder can i clean the 02 sensor or reset the wb gauge?

Thanks

 

Running rich for a short period of time usually will not destroy an oxygen sensor. I would check wiring and connections before you replace the sensor. Which hose came off? A little more background information might be helpful.

 

I always wondered about this as well.

 

Its the front hose connecting with the IC...

Its happen during my wangan on hway...

Thanks for the advise will check the connector & wiring tmr...

 

If its shortcircuited - NO. This might be a myth but I heard if you run it through a blow torch it will revive it. Anybody every heard of this?
