Position sensor

Re: Position sensor
It is quite common to find the wire had brushed up against part of the
exhaust and the insulation burned away causing a short or break in the wire.
If you find this it can be repaired.
Use wire of at least the same gauge, solder, and shrink-wrap the repair to
make it waterproof. Use plastic zip-ties to secure the wire and prevent a
repeat.

Re: Position sensor
look at the engine from the front. the cylinder head that sticks out farther
is the cylinder that is cy>#1 that's bank one or the cylinder head thats
closest to the raditor is bank one sensor then count o2 sensors from there
and u will get sensor 2 as being the rear sensor on that bank on the exhaust
