There are two sets of oxygen sensors on late model GM trucks. There are dual catalytic converters, one on each pipe coming off of the engine. In front of the catalytic converters are the first set of oxygen sensors. These sensors check the exhaust gases to see how the engine is performing. Based on the gases, the sensors send a signal to the computer telling whether to richen or lean out the air/fuel mixture. This insures optimal performance and fuel mileage. After the converters is another set of oxygen sensors. These sensors check the exhaust gases for cleanliness after having passed through the converters. These sensors don't directly affect engine function, instead they measure how well the converters are working. If a converter is no longer working properly or is clogged, they will lean out the engine so it will continue to function for a while, causing the 'check engine' light to come on. This is probably too much information, but I just wanted to be helpful. -Neal C.-
O2 sensors are mounted somewhere on the exhaust system. Usually on or near the exhaust manifold. There may be more than one. Go to www.autozone.com and look under component locations. It will give the location and number of sensors.
The 1998 GMC Sonoma was built in two engine offerings. The 4.3L V6 has three oxygen sensors; two upstream and one downstream. Upstream are part of the exhaust assembly before the catalytic converter.
Either in the exhaust manifold or the exhaust pipe right below the manifold. GoodluckJoe
on the driver side of the engine just below the front of the intake manifold.
where is (are) the location(s) of the oxygen sensor(s) on a 1995 Ford Thunderbird V8 ? I know where the front ones are I just can't seem to find the rear ones.
Bank 2 is the drivers side of your engine
Sensor 2 is in the exhaust after the catalytic converter ( downstream )
