2000 I30 P0158 Trouble Code

[jrc0109]

My 2000 I30 with 80,000 miles Service Engine Soon light came on two days ago. I just was able to check it and found a stored P0158 code with no pending codes. the P1058 trouble code was;
"TC1-P0158 o2 sensor circuit High Voltage Bankk 2 Sensor 2"

Replaced statrer about 3 weeks ago and relaced Mass air flow sensor about 2 weeks ago.

Any thoughts would be appreciated.

Replace the sensor labeled Heated oxygen sensor 2 (rear) (bank 2). You'll probably require a 22mm O2 sensor socket. As for the sensor itself, the OEM manufacturer is probably Bosch. You can get this Bosch sensor from Advance Auto Parts for $85.99 before tax if you order online, use coupon code VISA then pick-up in store.

I cleared the code last week. So far it has not reappeared. If it does, I will replace the O2 sensor.
Thanks for the help. Much appreciated.
