2G P1105 CEL Code

[Trison21]

How do I fix the P1105 CEL code "Fuel Pressure Solenoid Malfunction", I have a bone stock 1997 Mitsubishi Eclipse GSX.

Is there a fix for this?
Part number for the Solenoid?

Tried calling Mitsubishi dealership and they have no idea what a Fuel Pressure Solenoid is in KY anyways.

First check if vacuum hoses to it are leaking and it's connector is secure. It's coil resistance should be 36-44 ohms. If you have a vacuum gauge you can test for leaks in the solenoid when voltage is applied.

Mitsubishi part number is MD113721.

P1105 is a circuit code. Solenoid, wiring, or ECM failure. Verify you still have a fuel pressure solenoid and it is plugged in. Firewall near brake master cylinder. If you are unsure what solenoid, follow the vacuum line from your Fuel Pressure Regulator to the solenoid.

If it's bad get one used from miller import parts or post a wtb ad since many people remove it.
