Hello everyone looking to try and get some help with the code p053a I bought the car like week ago and fixed the o2 sensor and a new Cadillac converter Now I have this code I just put in a new intake hose with the PCV heater but still have the code and I am in limp mode I can clear the code but when I hit 1500 rpm the engine light come on with that code. So I'm looking to see if anyone know what is the couse or what I can try . I am also looking for what kind of volts I show get from the small 2 pin connector and what relay I have to test that is tied in with the PCV heater circuit I'm almost sure the two pin connector is in if I push any more I may break where it connects any help would be great and appreciate it thanks for your time
