Hey, Kurt...

<> I've had an intermittent "Check Engine Light" for a couple of weeks
 now, and I've finally been able to get a scanner connected to read
 it. It's showing P0138, about which the scanner's manual says
 "Oxygen Sensor Circuit /Heater High Voltage (Bank 1, Sensor 2)"

 After a brief search online, it looks like this is generally taken
 care of by checking the wiring from the sensor to the PCM, or by
 replacing the sensor itself.

 Any suggestions on anything else to check with this code? Also, if
 it comes down to replacing it, how difficult is it to replace this
 for someone who hasn't really spent much time crawling under vehicles
 over the years, but is starting to work on his vehicles himself more
 often, to try to save some money?<>

 If you're gonna replace one, you might as well do both of em while you're
under there. You'll need a special O2 sensor socket with a relief cut out of
it for the wire harness...NAPA has em.
As far as the O2 sensors, I got mine here http://www.oxygensensors.com/
(Thanx Bernd!).
Simple enough to change them out. I didn't even hafta jack up the DAKSY, but
I don't know what year or if you've got a 4X4 or not. Took me longer to
crawl under neath & get into position than it did to change both of em.
Good luck,
HTH
