whats up with this?My truck runs fine idles fine no check engine light,buut when i use my efi live tool and check for codes it keeps popping up
P0089
- Thread starter JRODS*LB7
- Start date
CIRCUIT DESCRIPTION code P0089
The engine control module (ECM) uses commanded fuel pump flow to determine a desired fuel rail pressure (FRP). The actual fuel pressure is monitored using the FRP sensor. If the FRP sensor indicates a pressure more than 20 MPa greater than desired, DTC P0089 will set.
CONDITIONS FOR RUNNING THE DTC
DTCs P0192, P0193, or P0641 are not set.
The ignition is ON.
CONDITIONS FOR SETTING THE DTC
The difference between actual and desired FRP is more than 20 MPa.
Commanded fuel pump flow is 100 mm(3)/second or less.
ACTION TAKEN WHEN THE DTC SETS - CALIFORNIA
The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
