on the rear exhaust manifold, directly behind the motor
Im the exhaust pipe.
O2 sensors are always located on the exhaust system.O2 sensors are always located on the exhaust system.
To replace the O2 sensor on a 2002 Pontiac Grand Prix with a 3.1L engine, first, ensure the vehicle is cool and then disconnect the negative battery cable. Locate the O2 sensor, which is typically found in the exhaust manifold or downstream in the exhaust pipe. Use an O2 sensor socket to unscrew the old sensor, then install the new sensor by threading it in and tightening it securely. Finally, reconnect the battery cable and check for any engine codes.
The O2 sensor is right off of the rear exhaust manifold, right of the transmission fluid dipstick.
the vehicle in question has 2 oxygen sensors one in the manifold and one by the converter.
This is one of the two sensors which is downstream directly after the catalytic converter.
no, these are unrelated to O2 codes. O2 cannot affect manifold pressure or intake air temp and of course not trans clutch.
for a 97-03 grand prix there is a front and rear o2 sensor. bank 1 sensor 2 is the sensor located on the exhaust near the catalytic converter (cat) also known as the REAR sensor... bank 1 sensor 1 is located on the back of the engine on top of the exhaust manifold or headers would be the street term. thats the FRONT sensor.
In the exhaust pipe.
if your check engine light is on change your o2 sensor. a bad o2 sensor will cause bad gas milage. also a dirty air filter or dirty injectors.
most o2 sensors on any car are located in the exhaust you should have 1 before that cat and 1 after and they are cylinder shaped with 4 wires coming out
There are 2 oxygen sensors. 1 sensor located right behind the engine (which is known as the upstream sensor) and one behind the catalytic converter (known as the downstream sensor). It is located at about the middle point of the vehicle on the top of the pipe. You will need an O2 sensor socket to remove the upstream sensor, and you will need an O2 sensor wrench with a pivoting handle to remove the downstrean sensor.
