EPC light should have nothing to do with the shift interlock,(EPC is traction control) should be a small cap or plug on the console, near the shifter that has the interlock disengage button,usually done with a key,check shift interlock in the owners manual.

Hello Zach. my name is Andy and to start with the best way is to connect the obd2 scan tool into it that way we can gomore straight to where the problem is and avoiding dealer fees or mechanic fees which they are really expensive and avoiding replace parts unneccessary

First off, let's simply define the OBD-II Trouble Codes:
Yes, 18032/P1624/005668 are the three codes that indicate "MIL Request Signal Active."
So, what does THAT mean (in plain English)??? This means that Fault Codes are stored in the TCM. SO WHAT'S THE SOLUTION?

Believe it or not, this could be a mass airflow issue. The mass airflow can trigger the lights the ASR and the EPC lights. When i gets really cold, the airflow sensor sends signals to the CPU to readjust the air/fuel mixture.

EPC means Electronic Pedal Control. Fly-by-wire for your gas pedal--instead of a mechanical cable that pulls an accelerator linkage on the engine, there's an electronic device on the gas pedal, an electronic device on the throttle body and a wire between them.
You should check the sistem with diagnostic tool.

check engine lights mean that a sensor is not giving the computer a signal within an acceptable range. when this happens the car will go into "limp mode" which means it doesnt use most sensors and will guess what it should do. you can continue driving and cause no additional damage but you will use a little more gas than normal. You should get it fixed but it can be put off till you have the money and time to do it.

try replacing the sending unit, It is easy but did it when the car is cold
