Thanks for your notes, Jon, though I wish I'd heard sooner. Based on
Brian's earlier post, I went ahead and visited oxygensensors.com and ordered
BOTH sensors: Walker, for $41.90 (front) and $54.90 (rear). I posted
"Seems like the next step is to replace both and see if the nagging code
clears." and hadn't heard anyone "stop" me. BTW, the local dealer wanted
$110 apiece for each one (MOPAR). All local parts stores carried the
dubious Bosch sensors (oddly, the AutoZone guy agreed w/ the bad karma
toward the Bosch units).
I appreciate your scoping OEM at Wyckoff Chrysler but, as I said, I went w/
the Walker units (they're on the way here).
Interesting that you thought it was only the UPstream sensor. In my earlier
post, I said:
Now let's turn to the Check Engine message I mentioned. I pulled the code
and it's P0132 (O2 Sensor Circuit High Voltage). Sensor 1 & 2 on Bank 1
read "1000V 0% S.T. fuel trim". This strikes me as a possible short.
"Sensor 1 & 2 on Bank 1"
This seemed (and still seems) like TWO sensors, though the error message
relayed to the scan tool may be cryptic.
You said:
If the downstream sensor were doing the same thing you would have gotten a
P0138 code as well.
Very interesting, and you may well be right, but this isn't what I got; only
the P0132 code that, when I went to the test tab, gave the info I listed
above.
Where does that leave us? Install the upstream sensor and see if the code
clears? If it does, hang the other one on a nail for next time?
