Hi I am new here .I have a 2004 Elantra gls and after rebuilding the tranny its still alive at 190K .Today my CEL came on for no apparent reason .I went to Auto zone and got these 3 Codes(I looked them up online as auto zone did not have my make and models codes)
P0030- Heated oxygen sensor (HO2S) 1, bank 1, heater control – circuit malfunction Wiring, HO2S, ECM
P2626- O2 Sensor Pumping Current Trim Circuit/Open (Bank 1 Sensor 1)
P2271 02 Sensor Signal Stuck
The only electric problems I have had with my car is the door being able to lock with the key left in the ignation(something that the car prevented before) and my autolocks only sometimes working/I aslo seem to burn out headlights brake lights often.Could these have to due with these codes? Thanks in advance for any help.
