[V6-12v] ODB Code 2342

[T. Jackson]

 Hi all.  The check engine light in my '95 90Q has started coming on
yesterday.  It comes on as soon as I turn on the car and sometimes turns off
while driving but comes back on again.  For the most part it is on more than
it is off.  I checked the codes this morning following the procedure on the
12.org site and the ECU returned code 2342 which refers to Oxygen Sensor 1
problems.  I did change my sensors a couple of years ago using the Bosch
universal 3 wire.  To connect them to the existing harness I used some butt
plugs.  I suspect that either one of them has come loose or has corroded
causing an open circuit.  I'd like to do a quick repair today as I am about
to go camping for the weekend and will need the car.  Can anyone tell me
which Sensor (driver side or passenger) Oxygen Sensor 1 is?

Thanks.
