After get battery replacement service in GM dealer, I got 'Service Engine Soon' light on dash board with code p0135 on my montana. Before that my car have not had any problem.
Once clear the code p0135 and removed Service Engine Soon light, but after runabout 17 mile the Service Engine Soon light comes up again.
If anyone have good idea on the problem? What could be problem and How to fix it?

Did you troubleshoot the code? Did you do any repair? 02 heater circuit, bank 1 sensor 1.

No. I only cleared code. But service engine soon light comes again after about 17 mile run.

Oxygen sensor, bank 1 sensor 1, heater circuit, according to the code #, the oxygen sensor is in the exhaust.

Oxygen sensor is part of a tune-up. Could be faulty sensor, could be issue with wiring circuit?

Thanks!
GM shop replaced with new part free after I purchased from Advancer Autoparts $27.
Thanks GM shop! It is reasonable service.
