I have 2 check engine lights(P0599 and P1497) Any idea what these might be?

was driving on the highway and stopped at a service station when it turned on.

 

P1497 is for an unmetered air leak...

Inspect your valve cover as this is likely the culprit, seeing as they like to crack.

I have had the code as well, but it was from leaving the PCV line open too long when I was seafoaming.

 

cool, thanks, ill check it out

 

hm, doesnt seem like the valve cover is the culprit...

anyone know anything about P0599?

 

According to:
http://www.clubmanregister.co.uk/vie...hp?f=14&t=1007

It is:
P0599 Thermostat Heater Control Circuit High

 

any update to this? i have the same code (P0599), but can't find it explained anywhere...

 

I had to replace my thermostat. Everything is good now.
