I was driving back home today and the check engine light came on so I stoped by AutoZone and they found this.

Number Crossed : P1133
Cross
Reference parts found:


Troublecode OBDII (Alpha) P Code

Troubleshooting P1133
H02S Insufficient Switching Sensor 1 / Bank 1
fuel control shifted lean (FAOSC)

So how do I fix it????

looks like you need an oxygen sensor, the heater element has gone bad and it's not coming to temp soon enough
