Question about 1997 Toyota Camry
P1133 refers to the air/fuel ratio sensor bank 1 sensor1 (This is the first O2 sensor in the exhaust). the code indicates that the circuit is either open, shorted, or has a poor connection. Most of the time this can be fixed simply by removing, cleaning, and reinstalling the sensor (checking the connections in the process). if after reinstalling (and having the code cleared from memory) the light comes back on you should replace the sensor.

there should have been a code book with the OBDII. If not take the codes to a garage near you and ask them, they might give you your answers. If not, I will bookmark this page and see if I can find my book and get back to you. RT
