I'm new to the forums but I have a question. My 03 Lancer es has a problem with the MAP sensor, the code is p0107 (correct me if I'm wrong) because it has low voltage. It idles rough n the rpms drop after driving a while to the point that the car turns off if I stop for too long (a red lightlight). I replaced the sensor n the problem continued so I used a multimeter to check the voltage n two of them are low while the other is at the proper level.

How can I fix this? I'm in the learning process for cars so anything n everything is really helpful

My advice for next steps would be to inspect the wiring harness, pay special attention to the terminals in the connectors for the sensor and the ecu. Use a multimeter to test continuity and resistance between the the two connectors. Also check all your chassis grounds, especially engine to chassis and ECU to chassis. Make sure they are tight and free of corrosion.
