My car threw these three codes:[/align][/align]P0134 -O2 Sensor CKT No Activity (Bank 1 Sensor 1)[/align]P0132 -O2 Sensor Circuit High Volts (Bank 1 Sensor 1)[/align][/align]P1116 -O2 Sensor Heater Circ.,Bank1-Sensor2 Open[/align][/align][/align][/align]I ordered a new MAF that should be in within the next couple days... what else do i need? A post cat O2 sensor?[/align][/align]

 

oh and i just threw P1020 - MAF

 

It looks like you need both O2 sensors, are you sure the second code is P1020?
The MAF codes i have are P1073 and P1074.

 

yeah look up P1020 it says: MAF or VAF A Circuit low Input
