So I just got a brand new oxygen sensor from zzp and put it in. But, now my car is throwing the p1133 code. I thought about putting the old sensor back in but figured id try and get some answers as to why a new sensor would do that.

Exact same thing happened to me. Get a denso O2 sensor
 
P1133 Insufficient switching Bank 1 Sensor 1. I hear that the ZZP sensors race sensors that are "lead safe" report to the PCM too quickly in some cases.
 
well the only real reason i got it from zzp is cuz it was cheaper lol but just a couple questions. 1. did you return yours to zzp and 2. could you point me to where i could get a denso o2 for not way to expensive?
 


Well I watched the voltage on it and it looked to be running fine. I just reset the codes today so guess I will wait and hope it doesnt come back
