So I just got my 04ss tuned yesterday and today my check engine light popped up it reads code p0036. anyone have any idea what that code is and how to fix? thanks!

 

I found this:
Should explain what that code might possibly be!

P0036 Description

Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.

 

Sounds like your front o2 sensor needs replacing

 

thanks guys! really appreciate the info!
