changed the head gasket today on my ls/vtec and the check engine light came on. held the gas pedal down and it flashed 6 times and 7 times. it will flash 6 times....stop....hold the pedal again and it flashes 7. does anyone know what these codes stand for?

 

Error codes are the same as OEM.

6 is Engine Coolant Temp sensor
7 is Throttle Position sensor
