Subject: DML: Oxygen sensor - 3 or 4 wire?
I'm going to replace my O2 sensor because A) I'm over 50K and B) my gas
mileage is in the crapper. I want to replace the upstream sensor
(pre-cat), right? The downstream I think is only used to monitor the
condition of the cat, as I recall.
Is this a 3-wire or 4-wire sensor? I can't tell from my glance at the
FSM and www.oxygensensors.com has both available for our trucks.
