the O2 Sensor Should be on top of your exhaust manifold
They are in the exhaust flow
1st o2 senor is between exhaust. 2nd o2 sensor is under shifter
The Achieva has only one O2 sensor. It is located in the exhaust system very close to the engine. Look between the back of the engine and the firewall, while the engine is cold. Starting at the exhaust manifold, move toward the catalytic converter until you see a plug sticking out of the exhaust pipe with a cable or wiring coming out of it. That will be your O2 sensor. --mark
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The O2 sensor bank 1 sensor 1 on a 1998 Oldsmobile Intrigue is part of the vehicle's emissions control system. It's located before the catalytic converter on the bank of cylinders that includes the number one cylinder, typically the driver’s side for V6 engines. This sensor measures the level of oxygen in the exhaust gases, allowing the engine control unit to adjust the air-fuel mixture for optimal combustion and emissions. A malfunctioning O2 sensor can lead to decreased fuel efficiency and increased emissions.
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
your o2 sensors are located before and after your catallytic convertors
it is the sensor that is just off the exhaust mainfold ussualy under the spark plugs
unscrew it
It depends on which o2 sensor.
