PO102 = mass airflow circuit low. Means there's a problem with the mass airflow sensor or circuit. Could be the sensor is disconnected, dirty, or faulty. PO340 = camshaft position sensor circuit. Could be ground wire disconnection, camshaft position sensor failed, PCM is failing, or even the crankshaft position sensor has failed. Good luck. Let us know how it turns out.

G.M.C. Savana 5.7 cranks but will not start. Its getting spark and fuel but still does not start.. Ran fine yesterday. obd2 code came up as po102 map sensor. I don't think this is the problem. Van should...


Let go with your theory

You get a PO102 MAF code.( Mass Air Flow Sensor)
Lets say the sensor is somehow not working correctly,and as you say,it has spark and fuel

I would guess, you think, the engine would be happy, having no idea how much air it is getting. Kind off like the computer will somehow overlook it is controlling an air pump in the first place.
