P1104 — Turbocharger Wastegate Solenoid malfunction

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

About P1104

P1104 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.

P1104 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 P1104 fault code relates to a malfunction in the turbocharger wastegate solenoid, the electrically controlled valve the PCM uses to regulate boost pressure. The solenoid is usually pulse width modulated and meters vacuum or pressure to the wastegate actuator so the turbocharger delivers the commanded boost. The PCM sets this code when the solenoid control circuit is open, shorted, or drawing current outside the expected range, or when the commanded duty cycle does not produce the expected boost response. When this fault is active the vehicle may show low or erratic b...
