Hello,
Here are the code means for the codes listed.
P0132 - O2 Sensor Circuit High Voltage (Bank 1 Sensor 1)
P0135 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P1132 - Lack of HO2S Switch - Sensor Indicates Rich (Bank 1 Sensor 1)
P0171 - System Too Lean (Bank 1)
P0172 - System Too Rich (Bank 1)
You have a sensor with the heater that is not good. Is the engine misfiring? This can make the rest of the codes come up. I would pull the spark plugs to see how they look. If one is black and the others are white or light color you have a stuck fuel injector on that cylinder FYI. Let us know how it goes.
