hello my cel light came on with codes p0154 and p0155 there both o2 sensor codes i cant for the life of me get to that sensor anyone have some tricks to get to it

 

You have to "get to it". The codes indicate an open circuit on the sensing element, and an open circuit on the sensor heating element. Could be burned wires, loose connector, damage O2 sensor. Its on the passenger side, 1/2-way down that branch of the Y-pipe.

Have you considered pulling the starter and the Y-pipe?
