So It looks like I will need to replace my O'2 sensors.
2000 Base 2.7.
I first got a code 5 years ago. cleared and watched. 3 years later - same.
This year, about 2 months ago, I did the same thing again. But the code came on last week.
So either the sensor is getting worse, and more quickly, or there is some other intermittent issue.
Either way, it is the same code 4 times in a row. So it is time to further diagnose. And with close to 80K on the odo, they are probably due soon anyway.
So, where to purchase?
Pedro - is there a source that helps you?
Others - is there a known discount code or good deal?
The usual suspects are close enough in price, it comes down to preference.
ON BTW - on the 2000, there are differences between front and back. I have seen it reported that the 4 sensors are the same., but two suppliers confirmed that is NOT the case. YMMV, but I will likely order 2 of each set. If they are the same, then no harm. If they are different - problem saved.
