Exactly

 

UPDATE

So I replaced the sensor *AGAIN* with aanother new Denso unit. Problem solved!

Until later yesterday afternoon, my CEL came.back on for the same p0130, and I check it out, and lo and behold, the voltage has dropped to 0.000 again.

The plug on the harness tested fine. These sensors are lasting maybe 50 miles before they die.

What on earth is going on???

 

Usually what kills them is coolant in the exhaust....

 

Compression test was great, no loss of coolant, not running too hot, no oil/coolant mixture... none of.it.

 

I'm a lil confused, may just be a misunderstanding. As I read this thread, it sounds like you are able to swap sensors side to side, and the code does not follow the sensor, but all the sensors do work fine on the unaffected side after swapping? Or does putting a sensor on the bad side of the engine actually kill it, so that it does not work on the good side when swapped over? That info will matter for diagnosis
