Car: 2003 996TT

Following up my previous thread on whether or not my MAF was failing (symptoms were inconsistent idle, over active airpump and ABS/PSM lights), I cleaned the MAF sensor with no result and increasing frequency of the issue.

Last week I threw a CEL P0102 - Mass or Volume Circuit Low. Cleared the code and the car continue to throw ABS/PSM lights with increasing frequency.

As such, I decided to replace the MAF Sensor. Now it does it everytime i drive the car. Additionally, it threw a CEL P0102 this morning.

My thoughts on next steps.

1. Check contacts in connector / wiring
2. Visual inspection for vacuum leaks / cracked hoses

Any other ideas?

1 and 2 are good ideas. Note that our cars are very particular regarding the MAF sensor. What brand did you replace it with? Anyway you can get a Durametric on it and find out the output voltage in real time? Do you have the stock air filter box and filter?

It's a Bosch MAF.

I will use my OBDII reader to see if I can.
