I had to replace my intake after a disaster happened during simple thermostat replacement. Now after putting in new sensors Air Intake Temp and Coolant temp I'm getting codes for both of them and Throttle position sensor, Fuel level sensor. They all say the same thing that : A circuit High
What would cause all these sensors to have to much power input. Is it a voltage regulation problem ? And can it be fixed without replacing PCM since there is no external regulator.
