Hello Scotty, I have a 2010 Infiniti G37. I got a P0603 code right after I pressure washed the car. Could you please give me some knowledge on what steps to take? I also have a 2013 Acura MDX, today I get in and start it up on the dash said emission problem and also trailer stability and I also had the skid light on the dash. If you can kindly direct me I will really appreciate it. Also I want to let you know after driving the Acura for a little while both errors disappeared on their own.

By the way, did you pressure wash the engine bay? If so, you could leave the car to dry and pray it works.

You need to scan the car for codes and go from there. It seems that the emission issue trips other codes.
No I did not wash engine bay. How ever I did spray underneath the vehicle. Is there any sensors I should be checking underneath the vehicle to check if water got inside of them ?
Check all the sensor and computer connections ( especially the PCM).
sounds like water may have gotten where it shouldn't.
