OBD-II Error Code P0253: How to Fix Injection Pump Fuel Metering A Low

Q: Can I drive my car with error code P0253?

You may be able to drive short distances if the engine runs, but reduced power and potential stalling make it unsafe. It's best to diagnose and fix promptly.

Q: What causes P0253 code?

Common causes include a faulty fuel metering actuator, wiring issues, contaminated fuel, or a failed ECM.

Q: Is P0253 a serious problem?

Medium severity. It can lead to poor drivability and further damage if ignored, but it is not immediately catastrophic.

Q: How do I clear code P0253?

Fix the underlying issue, then use an OBD-II scanner to clear the code. Disconnecting the battery for 15 minutes may also clear it, but it will return if the problem persists.

Q: Can a bad fuel pump cause P0253?

Typically no. P0253 relates to the injection pump metering actuator, not the low-pressure fuel pump.

Abstract

Error code P0253 means the engine control module (ECM) has detected that the fuel metering actuator on the injection pump is reading lower than expected voltage. This can cause reduced power, rough idling, or difficulty starting. The issue is often electrical, but can also be mechanical.
