how many oxygen sensors are on a 1997 Mazda mpv lx
On the 1997 Ford Aspire, the oxygen sensors are typically located in two places: one is positioned in the exhaust manifold, before the catalytic converter (upstream sensor), and the other is located after the catalytic converter (downstream sensor). These sensors monitor the oxygen levels in the exhaust gases, helping to optimize fuel efficiency and emissions control. If you're troubleshooting or replacing them, ensure you access the sensors through the engine bay and under the vehicle.
on exhaust pipe there is one right under the manifold
