2008 Sierra p2271

2008 Sierra, 4.3L auto 2wd

2 weeks ago I get P0141 and P0036. Oxygen sensor had a corroded wire right at the sensor. Replaced the sensor with a Bosch universal - there were no oem's available.

Last week, I got a p0128. Thermostat bad. Replaced, no more codes.

Today, I have a p2271 code. Same oxygen sensor as 2 weeks ago. Maybe the universal one isn't a good suitable replacement. I ordered an oem sensor to squash this problem.

Has anyone else run into this type of problem?

Wow, I just realized that I never posted a fix for this problem.

The p2271 was a bad "new sensor" twice from Autozone. I got a new Denso, and it went away.
