I checked my ECU the other week and my O2 and KS's needs to be changed. I replaced the O2 sensor and a new code came out. Here are the codes:

(1.) 10, 01 - Front Left HTD O2 Sensor Heater
(2.) 03, 03 - Front Left Heated O2 Sensor
(3.) 03, 04 - Knock Sensor

- What is the difference between the 1st and 2nd code?

- Are they the same?

- Are 1st and 2nd totally different sensor?

I replaced the Front Left Heated O2 sensor. Now it came back with the same error. Probably I install it wrong, I'm going to take it out, check the wires and reinstall it again. See if that will solve the problem.
