How many O2 sensors does the ES have?

4 posts in this topic

Just like that title says.

I have a p0171 code will be buying my own O2 sensors compared to the $450(+) that shops are trying to charge me. They cant figure out which O2 sensor is bad but the code has been an on going problem for about 3 years now. Numerous shops give different answers and I've checked and replaced everything besides the O2 sensors. I've looked online and i'm seeing O2 sensors for the Upstream, Downstream, and Center. I thought we only had 2 O2 sensors. Does anyone know the part numbers?

My car is a 2010 lancer ES 2.0L Non-California Emissions.

Having had to replace my entire exhaust system in my 2011 including the manifold, 49-state Lancers would have, as Mine indicated, two sensors.  Make sure the new front sensor has the long pigtail. 

Good luck!
