Mileage on the Jetta is 70,000, automatic transmission.
Jetta seems to run fine, no rough idle, no stalling, starts right up but got a waring light . I bought a scanner at your recommendation to see what codes it brings up: ECU1(#fd00), 01044 (Control module incorrectly coded), 01049 (Vehicle voltage terminal 50) no problem starting, 01214 (ECM), P01060 (MAP).
I am assuming my PCV manifold is leaking causing the MAP sensor to give ECM reading, vacuum hose leak? Your thoughts, Thanks!!!! 😡

You can clean the MAP sensor and replace your PCV valve and clean the MAF sensor.
