Q: i just replaced the o2 sensor on my van with a bosch replacement from autozone. the old sensor was intermittant. when the old sensor was working i would measure about .4 volts with the engine at normal temperature. this new sensor starts out at .5 volts cold climbs towards 1 volt and then begins to flip flop between .2 and .9 volts at about a one second rate. is this normal btw its a 1992 5.2l. tia yes thats normal. .
