P1103 — Turbocharger Wastegate Actuator malfunction

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Chrysler

About P1103

P1103 is a manufacturer-specific powertrain diagnostic trouble code recorded for Chrysler vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1103 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

For Chrysler vehicles, the P1103 fault code relates to a malfunction in the turbocharger wastegate actuator circuit or its mechanical operation. The wastegate actuator regulates boost pressure by controlling how much exhaust gas bypasses the turbine wheel, and depending on the engine it is operated either by an electronic actuator with internal position feedback or by a vacuum diaphragm controlled through a boost control solenoid. The PCM sets this code when the commanded wastegate position does not match the actual feedback, or when the actuator control circuit reads outside its expected rang...
