okay any and all help is greatly appreciated.

MY problem:

After scanning the car with an OBDII scanner, i pulled code P0135. This is the equivalent of 0901 if you use the self-check system. This code is the upstream oxygen sensor heater fault.

Now after researching this a little here (it's post # 17). I've come to realize that it's either the harness, or the sensor itself.

now here are my questions:

1. The harness is what plugs into the electical connector on the car itself, correct? What i mean, is that, if the harness is bad, the O2 sensor needs to be replaced, right? OR is it something else, and if so, where can i get info on that?

2. The problem sensor in this picture is the one in the most top-lefthand corner of the screen, right? The one with the "(RH)" after it.

3. IF i have to replace the sensor, where can i get it cheapest?

4. In searching for a good price, i checked oxygensensors.com. I'm a little confused, because according to their website the problem sensor would be the one described as "Sensor located in front manifold/exhaust pipe before catalyst on right side" (right?). Now there are 4 different choices, 3 of which have 3 wires, one has 4 wires. I'm not even considering the universal, because that involves cutting and splicing wires. How do i know which one i need, considering that they're all "OEM"?

PLEASE PLEASE PLEASE HELP!!!!!!!

PS> THe car is cali-spec. Any other necessary info can be given.
