Hi there . My name is ***** ***** Can we start with the last 8 digits of the vin number please ? Also , I need the full fault code number please ?

Customer: replied 1 year ago.
Hello the Vin# ***** ***** I am sorry I dont have the full codes as he just stopped at the truck stop and they gave him these codes. They were telling him first it was the filet but after replacing the filter it started doing this again, took it back and the guy said the fuel needs to be flushed out.

From what you have told me , 94 is definitely fuel related . But I can't tell you more without the rest of the fault

Expert:  Andy replied 1 year ago.

95 is for exhaust gas pressure sensor circuit. data erratic intermittent t or incorrect . This causes an engine derate .

Expert:  Andy replied 1 year ago.

Is there anything else I can do for you ?

Expert:  Andy replied 1 year ago.

The exhaust gas pressure sensor is a three wire sensor located by the thermostat housing at the front of the engine . I would start by checking the connector for damage . If all is good , replace the sensor .

The engine can respond poorly after motoring and/or the engine can have low power at high engine speeds


Fault Code: 482
PID: P094
SPN: 94
FMI: 1/18

Fuel Pressure Low - Data Valid But Below Normal Operational Range - Moderately Severe Level.
