What does P1106 mean?
P1106 is a diagnostic trouble code indicating "Dual Alternator Lower Fault/ Manifold Absolute Pressure (MAP) Sensor Circuit Intermittent High Voltage". The ECU is detecting a voltage reading that is below the expected range in the air flow sensors circuit. This typically points to a wiring short, a faulty sensor, or a grounding issue.
Common causes
- Damaged or corroded wiring harness
- Loose or disconnected electrical connector
- Failed air flow sensors sensor or actuator
- Blown fuse in the related circuit
