> [@Darrel1](#): > > P0507 came up. Throttle position sensor I don’t know where you got the explanation for the 507 code. This is what I find, A P0507 DTC trouble code may be caused by one or more of the following: A vacuum leak. Leaking air intake after the throttle body. EGR valve leaking vacuum. A faulty positive crankcase ventilation (PCV) valve. Damaged/failed/dirty throttle body. Failed EVAP system. Failed IAC (idle air controller) or faulty IAC circuit From: > **[P0507 Idle Air Control System RPM Higher Than Expected](https://www.obd-codes.com/p0507)** > > How to easily diagnose, repair, and info on causes of a P0507 trouble code that indicates a detected IAC idle air control valve that is seeing higher RPM than expected. Copyright [OBD-Codes.com](http://OBD-Codes.com) A TPS code would be P012x where x depends on the failure. By “trouble turning over” you mean it won’t start at all? Or it starts only after a lot of cranking? ---

My dad has a diagnostic scanner. Check engine light was on and that’s the code it gave off I typed in the code and vehicle info and that’s what came up. It’s weird dude I started the car twice today no biggie. And I’m leaving my grandmas house and it turned over but it dies out.
