greetings, we've had the check engine light come on for some time now
but only while running for about 15mins. finally bought a odb tool and
plugged her up and here's what came out. was wondering if someone can
give us some directions on fixing the cause of the codes. TIA

1) 33 Open/Short detected in A/C clutch relay (the car has no A/C)

2) 35 Open/Short detected in radiator relay
i assume just to replace the switch. can someone let me know where
this is located and if there are any special tools/method required to
retrieve it?

51 Sustain lean air/fuel ratio condition detect in 02 sensor bank 1
position 1.

i assume just to replace the o2 sensor. can someone let me know where
this is located and if there are any special tools/method required to
retrieve it? also, are there more then 02 sensor on the car?

thanks!

Follow the exhaust manifold from the block to the bumper. When you find
something with wires in it, you have found the O2 Sensor. It unscrews like a
spark plug.

Clear all of the other codes, and check again in a week or so.

I would fix the rad relay first and see if that changes the computer to
run not lean. The computer is supposed to switch from rich to lean
according to the temperature. If it doesn't see the signal correctly,
it can stay either lean or rich not switching setting code 35. Fixing
that might make code 51 go away.
