MAF Sensor for '99 ML320
#2
![Default](/forum/images/icons/icon1.gif)
Currently working on the ff DTC Codes:
PO 105 - Manifold Absolute Pressure, BARO Circuit
PO 173 - Fuel Trim Bank 2
PO 156 - O2 Ckt, Bank 2 Sensor 2
PO 170 - Fuel Trim Bank 1
Two pending:
PO 400 - EGR Flow
PO 155 - O2 Htr Ckt, Bank 2 Sensor 1
New MAF arriving Tuesday. Hoping to address 105, 170, 173. Then replace Bank 2 Sensor 2 O2 sensor.
When replacing O2 sensors, does it make sense to replace both of them or just the faulty one?
Will update developments next week.

Took a while but here's some progress.
PO156, PO173, PO155 are now all gone after replacing the O2 sensors.
PO105 and PO170 still lingers even after replacing MAF with a new one fm ebay.
What further action/checks can I do to fix the PO105 (Manifold A
bs Pres, BARO Circuit) trouble code? Should I buy another MAF and replace it again?
Would appreciate all help and advance thanks.
