Had the car in the shop with this code on the invoice: "P119 / History MAF / Fuel System Lower Limit"

MAF checks out OK, so checked for vacuum leaks. After some troubleshooting, there was a small cracked (original) rubber hose from intake manifold to MAP Sensor circuit joint, which sits above the fan shroud. Replaced hose - cleared code.

Here's a vacuum diagram for my car that's under the hood: https://www.autopartsapi.com/eEuroparts.com/images/parts/lg_d4a24495-9fe2-4de3-a04d-9bd49e342e71.jpg

Suspect hose is the solid black line from the RH side of intake manifold to the MAP Sensor.

Good to Go!

Technician wasn't too concerned about age and mileage on the original O2 sensors. His opinion is they're good until gas mileage drops or CEL illuminates. But from the preventive maintenance perspective, can't argue with replacing them sooner rather than later.
