2010 5.0L, 90k miles.
So.........had a few error codes recently for MAF, throttle position etc.
Replaced one MAF sensor and MAF codes appear to be resolved. Just did 300 mile error free trip. Now P219A fuel air imbalance has come up. Had this previously along with MAF code.
Research indicates:
Causes for this code may include: Engine vacuum leak (large) Defective oxygen sensor/s Burnt, chafed, broken, or disconnected wiring and/or connectors Engine exhaust leaks A faulty mass air flow or manifold air pressure sensor Bad fuel pump or clogged fuel filter
Has anyone fixed this particular code to give me an idea of most likely culprit? FYI have just had intake manifold off to fix coolant leak. Replaced inlet port seals and throttle body seals re. Air leaks.
Any suggestions much appreciated!
