Are you sure? Wide band sensors are not 35 bucks. Narrow band sensors are though. Also the bosch 4 wire sensor you described sounds like most narrow band sensors you'll find on any newer car in the junk yard, I know because I use them fairly often.

I've been here for a lot longer than 3.5 days and I know that's a line of BS as threads are moved on a whim. Perhaps a whim of multiple moderators but still without any discernable rhyme or reason. As long as two or mods agree though it must be legitimate.

Not all of the mods are full of bull, many of them do a good job, but a few of the bad ones get more notice.

75gmck25 The main reason for using a heated wideband sensor is that you have more flexibility on where to locate it since it does not depend on engine heat. Simple 1 or two wire sensors need engine heat to get to operating temps.

A heated sensor can be put almost anywhere in the pipe (even in the tailpipe) and it will still get a good reading. Just make sure its mounted in the top of the pipe with the electrical plug pointed upward or 30 degrees either side of straight up, so that moisture does not settle on the sensor.

ap72 That's a heated narrow band sensor, not a wide band.

LATECH When I replace an O2 with a generic one, naturally the wire colors/orientation are a question.Ohming it for the heater circuit is a good way.
Also like you said, I use a propane torch and a DVOM on volts setting to check the O2 sensor output, heat the sensor, let the heatstream from the torch pass across the vents or flutes of the business end of the sensor, and Voila...sensor generates a voltage.
Chinga dera, chingadara not sure how it is spelled, but it is a a funny way to say " a thing for which I know not of what it is called." LOL
Later Vato.

O2 sensor FYI

Maybe this can help someone.I have a barely used O2 sensor that Im going to put into my Camaro.I have one of those green,yellow,red o2 gauges (its a wide band) .The o2 sens.is a Bosch 4 wire,didn't know what wires were what so grab my v/meter the 2 white wires are the heater wires,they had resistance.The gray & black wires read o2 gases,gray is for the gauge,black is ground.When I put my meter on the gry. & blk. wire an ohm. them,it was open,so I applied heat to the working end of the sens.,changed meter to read voltage an got some low voltage readings.Im only using one o2 sens.I welded in one of those chingadaras for spark plugs, anti fouler things, use a 14mm.I welded it into the collector facing upwards.I don't see a need for a narrow band gauge if all your using it for is to get your carb. into the ballpark.Its been a big,big help in understanding & tuning the carb. Gauge was around 30.00,anti fouler was like 8.00, 02 sensors are (really all that is needed is a 1 wire sensor) about 35.00.
