You have two oxygen sensors in Toyota Rav4, One before the catalytic converter and another after.
A 2004 Chevy Blazer with a 6-cylinder engine typically has two oxygen sensors. One is located before the catalytic converter (upstream sensor), and the other is located after the catalytic converter (downstream sensor). These sensors monitor the exhaust gases to optimize fuel efficiency and emissions control.
It depends on number of cylinders the engine has. 4 cylinder engine has 2 oxygen sensors. V6 has at least 3.
There are 2 Oxygen sensors. One is on top of the catalytic converter called the upstream and the other is at the bottom of the catalytic converter called the downstream.
The 1998 Chevy Astro van is equipped with two oxygen sensors. One is located before the catalytic converter (upstream), and the other is located after the catalytic converter (downstream). These sensors monitor the oxygen levels in the exhaust gases to optimize engine performance and emissions.
4. 2 pre cat, 2 post.
2, one before and one after the catalytic converter
I believe there are 2 oxygen sensors that are used for air / fuel ratio and 2 oxygen sensors that are downstream from the catalytic converters and are called catalyst monitors
three
