Can I replace a air fuel sensor (upstream) myself? on 2001 Toyota Tacoma

I recently replaced the fuel filter. Now the check engine light has come on and codes are as follows: p0125, p1135 & p1130. Advise?

P0125 = low coolant temp, Check your coolant level and thermostat operation. P1135 & P1130 are both = Air/fuel sensor codes. Yes you can change an air/fuel sensor yourself, just make sure you use some anti-sieze on the threads, dont over torque the sensor (14-17 ft. lbs. max) and clear the codes once repairs are completed.
