I replaced a sensor in that location, called the Air
Charge Sensor. But am unable to locate the Ambient
Temp Sensor. Going to the dealer is a great idea, but
the charge to hook up the computer is $80+the parts if
I don't pay them to fix it at $76 an hour, all I have
spent so far is $30. If I can locate the last sensor,
the only thing left is the battery as I have an extra
PCM.
Still throws a code #23&37
