Check engine light comes on i hooked up my code reader under the steering wheel and it threw this code PO133 any idea's of what it is or how to fix

Code P0133 indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

This may mean that one or more of the following has happened:
The oxygen sensor is faulty The wiring to the sensor is broken / frayed.
There is an exhaust leak.

The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:

• Check and fix any exhaust leaks
• Check for wiring problems (shorted, frayed wires)
• Check the frequency and amplitude of the oxygen sensor (advanced)
• Check for a deteriorating / contaminated oxygen sensor, replace if necessary
• Check for inlet air leaks
• Check the MAF sensor for proper operation

Code p 0133 has 3 references
1 heated oxygen sensor (HO2S) 1 bank 1---slow response ===causes--heating inoperative--wiring---HO2S
2--oxygen sensor(O2S) 1 bank 1---slow response --===causes --wiring---O2S
3---heated oxyhen sensor (HO2S) -1 bank 1-- no signal===causes wiring ---HO2S
The HO2S is the unit in the exhaust manifold or before the cat converter and is subject to wire failure at the unit
use the correct socket when replacing it as the wires are fragile and easily damaged
