I think v6 has 3-4 (cali vs. fed). I4 should have 2.
It should have at least, usually 4 though.
One of sensors is failing, maybe the O2 sensor(s).
There are four o2 sensors on a montero sport.
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).
The 2003 Mitsubishi Eclipse GTS with a 3.0L V6 engine typically has four oxygen (O2) sensors: two upstream (pre-catalytic converter) and two downstream (post-catalytic converter). These sensors monitor the exhaust gases to help optimize fuel efficiency and emissions control. If you're troubleshooting or replacing them, it's important to ensure you have the correct sensors for your specific model and engine configuration.
There is a total of 3 O2 sensors 2 Upstream and 1 Downstram
i have a 2001 f250 v10 only have 2 o2 sensors
The 1992 Ford Taurus has two oxygen (O2) sensors. Both O2 sensors are located upstream of the catalytic converter with one on each exhaust bank.
2 upstream and 2 downstream for a total of 4 O2 sensors.
Three
There are two.
