Anybody thrown a P1133 code?

It is o2 sensor insufficient switching b1s1.

Just had the exhaust apart fixing leaks with SENSOR SAFE SILICONE :eek2:

Erased the code, pulled out the sensor and everything looked okay(like you could tell a bad sensor by looking :eyes: ) Then went for a drive and everything was fine (no more codes)

Anybody else ever get this code?
