Hello everyone. I posting to ask how many o2 sensors are in a 2006 ES 2.4 cyl galant. I thought there were only 2 in the 4 cyl (one in the upper front of the car near the engine and one near the cat converter) but it seems there are 4 according to a website i viewed on the net.....http://www.redlinemotive.com/store/r...=Oxygen+Sensor
Can anyone provide clarification. Thanks A lot.
There's 4. Top are b1s1 and b2s2.
The bottom are b1s2 and b2s2. Bank 1 is the closest one to cly 1
Thanks Gotti. According to the scanner at autozone "Catalyst efficiency is low-bank 2". Where exactly is the bank 2 cat sensor located if i am standing in front of the car?
p0431 bank to cat is below thershold. bank 1 and bank 2 cats are the exhaust manifold. the cat convertor failed.
