OBD-II Error Code P0250: Injection Pump Fuel Metering Control – How to Fix It

Q: Can I drive my car with error code P0250?

It is not recommended. The vehicle may experience reduced power, poor fuel economy, and potential stalling. Have it diagnosed and repaired as soon as possible.

Q: What causes error code P0250?

Common causes include a faulty injection pump actuator, wiring issues (corrosion, shorts), low fuel pressure, a defective ECM, or a failing injection pump.

Q: What does 'injection pump fuel metering control' mean?

It refers to the electronic system that regulates how much fuel the injection pump delivers to the engine. The ECM controls this to optimize performance.

Q: How much does it cost to fix error code P0250?

Cost varies widely: DIY repairs may cost $50-100 for parts (e.g., actuator). Professional repair can range from $200 for simple wiring fixes to $1500+ for injection pump replacement.

Q: Can a bad fuel filter cause P0250?

Yes, a clogged fuel filter can restrict fuel flow, causing low pressure and triggering this code. Replace the filter as part of basic maintenance.

Abstract

Error code P0250 indicates a problem with the injection pump fuel metering control circuit. This usually means the engine control module (ECM) has detected a malfunction in the electrical or mechanical components that control fuel delivery. If left unresolved, it can cause poor engine performance, hard starting, or reduced fuel efficiency.
