The Engine Control Module (ECM) detects the following condition:
•The primary fuel level signal voltage is above the acceptable range for more than ten seconds.
The fuel level sensors are OEM installed components for the vehicle. The sensors are selectable through a customer programmable parameter and the customer programmable parameter may be protected by customer passwords.
Possible Causes:
1) Loose ECM Connection/Harness
2) Fuel level sensor failure
3) WIring between fuel level sensor & ECM
