under the power steering pump in the top of the engine.
Where is the speed sensor located on a 1997 Oldsmobile Aurora
The O2 sensor is in the rear exhaust maniford. It can be changed from above, but you'll need to use a mirror or work by braille.
Under hood, center, rear engine area, mounted in exhaust manifold
There are actually two oxygen sensors on a 2000 Oldsmobile Silhouette. There is one located in the exhaust system just before the catalytic converter. There is also another oxygen sensor in the air intake tube leading from the air filter.
if it has a 3.1 or 3.4 it is located between the engine and the trans just above the oil pan.
If you are referring to the "fuel tank pressure sensor", it is located on top of the Gas tank. The tank will need to be lowered or removed to access it. TechJK ----------------------
For 3.5l, remove starter.
Bad temperature sensor? Plugged or restricted radiator? Water pump not circulating coolant? Thermostat not opening? System airbound?
On the 3.8 litre engine its located on the forward side under the harmonic balancer. You need to pull the balancer to replace the sensor. The magnetic pick-up on the sensor rides in the stainless steel stotted track on the rear of the balancer.
On July 3, 2008 I was quoted $120 to change one oxygen sensor on a 98 Silhouette. Since the part is probably around $80, I would guess $40 is for labor. This is in Texas. Gary
