O2 sensor? codes P0155 P1151

[John Hutchinson]

My Check Engine light is on and the engine runs very slightly rough at low idle. NAPA service tells me the codes are:

P0155 - O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)

P1151 - Lack of HO2S21 Switch Sensor indicates Lean [Bank 2 upstream]



and they will repair for $173.02 (includes $68 parts; $96 labor).



I would appreciate any advice from the experts out there - does this sound like a reasonable diagnosis and cost to repair? Is this a repair any of you have done yourselves?

Thanks in advance for any additional info.

The o2 sensors on the trac are out in the open and very easy to change. From what I have seen you wont need an o2 socket. Can be got to with a regular wrench.

Save yourself the $100 labor.

They are easy to change with an open end wrench.......
