code 44

Getting Code 44. I've got an AFS-74 O2 sensor, and I guess it needs to be replaced. However, I think that one is not available anymore. What are you all using for O2 sensors?

Thanks.

Got a scan tool, if so what are your readings? As for replacement, I found a match at autozone's site but looks like different connetions to me. OEM: 25312179 | Oxygen Sensor | AutoZone.com


or Try Casper's electronics CEI - Casper's Electronics, Inc.

I don't know your location but if it's here in the states, like me for example.

I can order an o2 sensor and have it delivered to my door for less than what i can get one at the local parts stores and not have to pay taxes on it,it just takes a few days so i plan ahead.

Denso part # 2341001 is a direct replacement with the correct single wire connector.

AFS-74 O2, your needing the HEATED O2 right? or Single wire?

Both should be able to get at local autoparts stores or buick vendor.

I've got a Scanmaster. That's how I learned of the code.

I heard the AFS-74 wasn't available anymore. I'll look into it.

Yeah. I'm using a heated O2 sensor.

I have 2 AFS-109 AC Delco sensors still in the original bag that have been on the shelf for years [made in USA ].

I think these were a replacement for the AFS-74?

Check with Casper's as John should know if they interchange. The difference, if any, should be with the 4 pin connector or wire length.

These are part of a large stock of Casper's items I carried so they will work for a turbo Buick with the proper adapter harness.
