Help: Error codes 996 Carrera 2

[92tsiawd]

Hi Guys,

I am a little stumped right now, searched around and haven't seen another car with this combination of error codes.

Car Info:

My car is a 2002 911 Carrera 2 w/ 60k miles

I just replaced the Maf with a brand new unit from Suncoast.

P1109 - Input variables, charge measurement

Above limit

P0430 - Factory Fault Code 45 - TWC conversion, Bank 2

Above limit

Any ideas as to what I should be checking? O2 sensor? which one? Catalytic? Thanks in advance

P1109 Input variables, charge measurement - above limit

Possible fault cause

- Heavily soiled throttle

- Throttle adjusting unit faulty

- Mass air flow sensor faulty

P0430 TWC Conversion, Bank 2 - Above Limit

Possible fault cause

- Oxygen sensor ahead of and after TWC exchanged

- Valve lift fault

- Aged oxygen sensor after TWC

- TWC faulty

I would start with a good cleaning of the throttle body and MAF (using the proper cleaners) - clear the codes and test again.

Shoot, forgot to mention that I did clean the throttle body yesterday. MAF is a brand new Bosch unit from Suncoast.

Code came back exactly the same after the cleaning.

Well that kind of leaves the throttle jacking unit.

Does the Throttle Jacking Unit have anything to do with the Throttle Position Sensor? Do I have to replace the entire throttle body?
