Banks and sensors.

[RangerPilot]

In regards to O2 sensors, is bank 1 the driver's side or passenger side on a RWD vehicle?

I had a code pop for bank 2, sensor 1. I thought bank 2 was the passenger side but reading online has a lot of contradictory information.

Bank 1 is the bank that has #1 cylinder on it. Most generally, the passenger side on a Ford is bank 1.

Bank one is on the passenger side for your truck as well as most Fords like Blacksnapon stated.

Since the 4.0L SOHC is German (and thus...weird), does this also apply?

Yep! An easy way to find #1 is to look at your motor from above. One cylinder head will be a little closer to the front. Thats bank 1

The picture I posted was what Alldata says for 4.0L SOHC. If you give me the engine code from the vin I can verify it, but it should be pass. side.

The passenger head was slightly behind the driver's head...so I think that makes pass side bank 2, so I replaced sensor 1. Haven't driven it yet...got a little too busy today. Will drive it tonight.

Will the CEL clear now that the sensor is replaced, or do I need to have them cleared?
