check engine light PO 125
My check engine light is on in my 99 sc with P0125 as the only code, does anybody know what I should check first, maybe O2 sensors?

Indicates the ECT or CHT sensor has not achieved the required temperature level to enter closed loop operating conditions within a specified amount of time after starting the engine.
possible causes:
Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Malfunctioning ECT sensor
Malfunctioning CHT sensor
...
checked alldata and according to that it points to your front oxygen sensor. I'm more inclined to go by this than my previous post.
...
code desciption points you in the wrong direction ....... O2 is the cause, and was damaged by coolant when the head gasket failed.
