1996 LT1 O2 Sensor
hey everyone -
i have a quick question here (see title) it seems as though each year - in the march / april time frame - over the past few years, my check engine light comes on.. using the scanner, it is always code P0151 - which is a faulty right front 02 sensor.. i'll replace the sensor, and then in a year, it will go bad again.. wash, rinse, and repeat... what would cause this part to fail so early? they are recommended to be replaced, what? every 30K miles or so? i am not driving that far each year...

Re: 1996 LT1 O2 Sensor
Are you losing coolant? The silicates in the coolant, if escaping into the exhaust, could be contaminating the sensor.

Re: 1996 LT1 O2 Sensor
A bad or failing cat can cause the 02 sensor to fail
