my ultragauge set off a pending P1133 code (HO2S Insufficient Switching Sensor 1)

i just changed my (upstream) o2 sensor this spring, but it was a bosch... but still it has less than 5k miles on it. could it be bad ALREADY or what

I don't know if it's just my luck man, but i have never had any dam luck with aftermarket sensors in mine. I went through 3 bosch sensors in under a year. Kept replacing them under warranty. Finally, I got pissed off and forked out for a Delco and have been good since. Almost 2 seasons on the Delco one now. Close to 200 bucks for it though, that part sucks! A dam NTK/AFX Wideband replacmant sensor for my tuner is cheaper!!

update/bump.

p1133 keeps setting, but the upstream o2 readings look normal... no lag.. the sensor wires look good, no damage..

should i just spend the money to get a better o2 sensor or could this be another problem??

also if i DO buy an ac delco sensor, can i take the bosch back under warranty? (bought from autozone)
