Specs At A Glance

Good To Know

Q: Can a failing MDS solenoid cause misfire-like symptoms? A: A failing multiple displacement solenoid can cause rough idle, hesitation, and trigger diagnostic trouble codes such as P3400 or P3425, which may feel similar to an engine misfire.

Q: Is a PCM reflash required after replacing this solenoid? A: Generally no reflash is necessary, but clearing stored trouble codes and allowing the ECM to relearn MDS operation is recommended to ensure seamless cylinder deactivation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
