2009 Kia Rondo P0106 Fault: Recurring Engine Cut-Off After MAP Sensor Replacement

My 2009 Kia Rondo has been experiencing intermittent engine cut-off, especially in traffic. The issue initially triggered a P0106 fault code (MAP sensor malfunction). I cleared the code and drove for several days without issues. However, after a few more drives, the car suddenly cut off while driving. Restarting resolved it temporarily. I replaced the MAP sensor as recommended, but the problem returned. The vehicle now shows P0106 again, along with additional codes such as P0108, P10113, and P0111. A recent visit to a Kia dealership revealed no visible faults—though they noted a potential manifold leak based on a cleared code. However, I don't see how this would directly correlate with the P0106 MAP sensor fault. Possible causes for P0106 include: - Faulty or degraded MAP sensor - Water or dirt intrusion in the MAP sensor connector - Intermittent open or short circuits in the reference, ground, or signal wires - Corrosion causing intermittent grounding issues - A break in the flexible air intake duct between MAF and intake manifold - A failing Powertrain Control Module (PCM) I have ruled out physical damage to the intake system. The issue comes and goes, suggesting an electrical or sensor-related problem. I'm now considering whether a PCM failure might be responsible—especially since replacing the MAP sensor did not resolve the issue. Next steps: Verify voltage and ground connections at the MAP and IAT sensors. Referencing wiring diagrams from sources like alldata.com may help identify potential circuit faults.
