P0089 trouble code definition

P0089 is Fuel Pressure Regulator 1 Performance, indicating a problem in the fuel pressure regulator system.

This code is similar to P0090.

What the P0089 code means

The P0089 is a diagnostic trouble code (DTC) for a fault found with the fuel pressure regulator. The fuel pressure regulator regulates how much fuel is delivered to the fuel injectors.

The ECU controls the fuel pressure regulator and when a fault is detected the P0089 code is set. This code will remain until the problem is resolved.

What causes the P0089 code?

  • Failed fuel pressure regulator
  • Clogged fuel filter or screen
  • Restricted fuel lines
  • Fuel pump output not meeting specifications

What are the symptoms of the P0089 code?

  • Check Engine Light illuminated on the dash
  • Vehicle may run poorly
  • Lean or rich conditions
  • Poor acceleration and lack of power

How does a mechanic diagnose the P0089 code?

  • A qualified mechanic will begin by hooking up an advanced level scan tool to find any codes stored in the ECM. Any codes present will have its own freeze frame data that tells the mechanic under what circumstances the DTC was set, like RPM, vehicle speed, coolant temperature, etc.

  • Codes will then be cleared and the vehicle will be taken on a road test.

  • Upon the code returning a visual inspection will be performed looking for any damage or leaks from the fuel lines, damaged fuel pressure regulator, or restricted lines.

  • If the visual inspection is passed fuel pressure will be checked at the test port.

  • The fuel pump output will be checked using a scan tool, as well as the fuel pressure regulator to check for proper operation.

Common mistakes when diagnosing the P0089 code

  • Common mistakes are easy to make when performing diagnosis. They happen when steps are not followed in order or are skipped completely.

  • Though a failing fuel pump is the most common cause proper tests must be performed on the fuel pump before it is condemned and replaced.

  • If parts are replaced before they are tested it can be a waste of time and money and not fix the issue present.

How serious is the P0089 code?

P0089 may be an indication of a failing fuel pump. Once the fuel pump fails the vehicle may stop running while driving or fail to start and run.

The other symptoms such as poor vehicle running, misfire, lean, and rich conditions can cause the vehicle to become unsafe to drive. Diagnosis of P0089 should be performed ASAP.

What repairs can fix the P0089 code?

Additional comments for consideration regarding the P0089 code

Two specific tools will be necessary to properly diagnose P0089. First is a manual fuel pressure test kit. This will allow for fuel pressure readings to be taken at the fuel rail. This is critical for accurate testing.

The other tool required is a professional level scan tool. Advanced scan tools allow live date to be seen and changes over time. Scan tools allow us to see things such as sensor data, fuel pressure, voltage, ohms and other important information.
