Details of the Cadillac p1106 OBD Code
Cadillac fault code P1106 relates to the Manifold Absolute Pressure (MAP) sensor circuit range/performance issue.
OBD code P1106 for Cadillac vehicles indicates an issue with the Manifold Absolute Pressure (MAP) sensor circuit.
This code is triggered by the Engine Control Module (ECM) when it detects a voltage signal from the MAP sensor that is outside of the expected range.
The MAP sensor measures the intake manifold pressure, providing crucial data for fuel delivery and ignition timing.
When the ECM receives abnormal signals from the MAP sensor, it can lead to drivability issues and poor engine performance.
Mechanic’s Tech Notes
Detailed information on diagnosing and repairing Cadillac fault code P1106 related to the MAP sensor circuit.
To diagnose OBDII code P1106 on a Cadillac, start by visually inspecting the wiring harness and connectors related to the Transmission Control Module (TCM).
Look for any damage or corrosion on the components and connector pins.
Use a multimeter to check the TCM’s power and ground connections for proper voltage levels.
Additionally, use a scan tool to confirm if the TCM communicates over the Controller Area Network (CAN) network.
If necessary, consider reprogramming or reflashing the TCM to address the issue.
