My thermactor solenoids (a.k.a. AirManagement1 & 2 solenoids) are defective, and need replacing. I came across this sensor package from FRPP for $90 which includes, 2 O2 Sensors, EGR Vacuum Regulator, and from the picture it looks like a MAP sensor. How come it's so cheap when a single Motorcraft O2 Sensor is $75 for my car? Am I missing something here?
