Check Engine Light..P0136..Need help.

[jelly53]

Well today the engine light came on my 97 corolla < P0136 >. O2 Sensor Bank 1 sensor 2. A while back I did replace the front sensor. This seems to be the one on the back. I went to rockauto and found the rear O.E type for about $75-$85. I was looking into either BOSCH or DENSO. There is not much of a price difference between the two. I did replace the front one with BOSCH. Any info on installation would be appreciated. Thanks
So what you guys say BOSCH or DENSO???.....

Bosch.

Denso is good, it's probably what Toyota put on the car in the factory.

DESNSO=Made in Japan
BOSH=Made in China

You can also cheapen up the price a little if you want to put the connector on yourself. I dont know why they charge an extra $30 for having an OEM style connector on the sensor. Most stores will list a "universal" with no connector and the "OEM" sensor with the connector.

I'll also add that many times you can "revive" an O2 sensor just by wire brushing it. Engine deposits cover up the slots in the sensor so it cant read correctly.

where is the exact location of the rear o2 sensor? Is it right after the cat converter?
