I will assume these are P codes per SAE.
P0133 - Oxy Sensor Circuit Slow Response(Bank 1, Sensor 1)
P0136 - Oxy Sensor Circuit(Bank 1, Sensor 2)
P0141 - Oxy Sensor Heater Circuit (Bank 1, Sensor 2)
The 0133 and 0136 may have a dash indicator light show up. Sure you dont have a 0135? Same as 0141 but for Bank 1 Sensor 1, and 0135 may also cause a dash indicator light come on.
Nevermind, editing because I had an 0136 for sensor 1, but it is sensor 2. So I should have asked if you had an 0139, same as the 0133 but bank 1 sensor 2. Seems weird you are getting codes for two sensors instead of just one.
