2004 Toyota Tacoma OBDii P0136 (Bank1 Sensor2)

External Since: Jan 05, 2006 Posts: 2

Good morning.
My Taco is throwing a P0136 which is circuit malfunction: Bank1 Sensor 2.
This is the after converter o2 sensor.

My question is:
I have NOT remove this yet ... maybe this is my weekend project.

The cord on this sensor looks to be about 4 feet long and goes up thru the
cab.
Do I have to remove the passenger's seat to connect this? The connector
runs thru the cab under the passenger's seat, or am I missing something?

Thank you,
Randy

Were the O2 sensor harness passes through the floor there should be a
rubber grommet that is part of the harness. Pry that grommet out of the hole
from underneath and you should be able to bring the connector out through that
hole.
