Codes P2243 & P0135
I had P2243 come up after 3 week of buying the car so I deleted it to see how long before it came back on and 2 week later the engine management light came up so I expected it to be the same code but it came up P0135 any help will be appreciated.
P2243 - O2 sensor reference voltage circuit/open bank 1 sensor 1
P0135 - O2 sensor heater circuit bank 1 sensor 1
Thank you 🙏
