Jetta 1.8 stalls p0322 code and epc lamp on

The 102 code is a Mass Airflow sensor circuit code. It saus the voltage output was below expected.
the 322 is a crak sensor/RPM sensor code saying it didnt see it on at least 1 occaision when expected.

The crank sensor code can be accidentally triggered by long cranks, low battery, or stalls and there may be nothing wrong with the crank sensor.

The MAF sensor code can be caused by a defective MAF, a large air leak downstream of the MAF or in the PCV system causing the MAF to miss sensing too much of the air thats going in and therefore reading low voltage compared to RPM and Throttle position.

Any time the MAF is reading wrong, due to an airleak, timing issue, or defective MAF, an EPC lamp will follow. This just means that the accelerator pedal was in a certain position (wherever you pressed it) and the computer expects a certain MAF reading and a certain throttle reading and a certain RPM and LOAD reading all to match together. If any of them is too far off, you get an EPC light warning you the pedal didnt match something else that was expected.

If the crank code doesnt return after clearing, ignore it for now. The MAF code should be checked 1st with leak tests or smoke tests by a competent mechanic. If you SEE any loose, broken, or cracked hoses with a visual test; you can reattatch or repair those and hope for the best and it may be OK. If you dont see an obvious hose leak, you will likely need to replace something that is causing readings of 2 sensors to mismatch. COuld be the PCV/Oil seperator, throttle body, pedal sensor, or MAF. Guessing could get very expensive very quickly, so my recommendation is have a professional check it properly.

Hi Greg, I'm AL the owner of Big As Auto Repair in St Charles Mo

Greg, I read your complete message, but nowhere did I see that you replaced the Cam Sensor. The EGR will cause it to stall at stops but usually will not prevent it from restarting. I would try replacing the Cam Sensor before anything else. If you should need further assistance go to my website by clicking here: Auto Repair

Check crankshaft sensor.

check cat converter

your battery or you alternator is not performing properly depriving the engines ignition system of the volage necessary to keep the engine running. the EPC light came on because raw fuel was sensed by the o2 sensors

Sounds like you have a small bit of dirt or grit in the fuel system when accelerating it is drawn with enough force to cut off the fuel supply then is released when engine at Idle.
1 run liquid fuel line/injector cleaner in 1 tank
2 check fuel lines for debris
3 change fuel filters
4 have fuel tank flushed
here is trouble shooting order less expense to greater.

Have you check the O2 sensors? How baout cleaning the MAF and Throttle body? Thermostat?

How does the temp gauge look whn it stalls?

need to recalibrate the throttlebody

seems like an air-locked gas tank (remove gas cap as a test) or dirty fuel filter....
