In a 2003 Pontiac Montana, the oxygen sensors are located in two main areas: the upstream (pre-cat) sensor is situated in the exhaust manifold or just before the catalytic converter, while the downstream (post-cat) sensor is located after the catalytic converter in the exhaust system. These sensors monitor the oxygen levels in the exhaust gases to help optimize engine performance and emissions. Accessing them may require lifting the vehicle for easier reach.
The 2003 Pontiac Aztek is equipped with four oxygen sensors. There are two upstream (pre-catalytic converter) sensors and two downstream (post-catalytic converter) sensors. These sensors help monitor the air-fuel mixture and the efficiency of the catalytic converter for optimal engine performance and emissions control.
The o2 sensors on the 2002 Pontiac Grand Am GT are found screwed into the exhaust pipe. There are 2 of these on the 2002 Grand Am GT.
yes
how many o2 sensors on a ford e350 van 2003
The 2.5 has 2 O2 sensors (both on top of the engine) and the 3.5 has 4 O2 sensors (two on top, and two under the car).
Exhaust pipes
There are two o2 sensors made for the 2001 Pontiac Aztek. Both are located on a exhaust piping of the vehicle. One is closer to the exhaust manifold, while the other is closer to the catalytic converter.
2
YES
If you mean o2 sensors, there is one. It is located on the exhaust manifold on the back side of the engine. Gm started the two o2 sensors around 94-95 when obdII was adopted.
There are two oxygen sensors in a 2003 Sonoma V6 with a 4.3 liter. Prices for the sensors start at $69.95.
It has 4 of them.
