What is P0253 : Engine Error code Causes Explained
This Guide covers the P0253 engine fault code, which signals a low fuel injection pump fuel metering control “A” (cam/rotor/injector). Poor engine performance, rough idling, and stalling might result from this DTC.
How to Identify a DTCs Number
The Diagnostic Trouble Code (DTC) P0253 is related to the fuel injection pump fuel metering control circuit.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
To identify P0253, connect an OBD-II scanner to your vehicle’s diagnostic port and retrieve stored error codes. This error typically occurs when the Powertrain Control Module (PCM) detects an issue with the fuel metering control circuit in the injection pump, leading to improper fuel delivery.
Causes of P0253 Code:
- Fuel contamination:
Fuel can become contaminated by bacteria, corrosion, or dissolved waxes. - Wiring issues:
Wiring and connectors can become damaged, shorted, or corroded. - Open circuits:
Engine vibration can cause open circuits. - Defective fuel components:
The fuel pressure sensor, fuel control actuator, high-pressure pumps, electric lift pumps, or fuel shut-off solenoids mav be defective
Risk Level of P0253 Error Code:
High Risk Level means potential fuel delivery issues, leading to poor engine performance, rough idling, stalling, or difficulty starting.
When facing a P0253 code along with by a “High Risk Level” warning, it’s essential to take immediate action.

- Chevy
- GMC
- RAM
- Ford
- Mercedes Benz
- Volkswagen
