Chevrolet Corvette
Condition
Some owners may comment about inaccurate/erratic fuel level gage reading conditions such as those indicated below:
^
Fuel gage suddenly drops to E (empty) and CHECK GAGES message illuminates (DTCP1431 or P0461 set).
^
Fuel gage does not go to F (full) after filling fuel tank.
^
Vehicle runs out of fuel while the gage still indicates fuel is available.
Cause
The conditions indicated above may be the result of one or a combination of more than one of the causes indicated below:
^
Stuck or intermittent sticking of the sensor float arm.
^
Clogged/restricted R.H. fuel sender assembly jet pump.
^
R.H. jet pump unable to transfer fuel due to fuel vaporization resulting in bubble accumulation in the fuel strainer.
Correction
Inspect the Julian date codes located on the bar code labels attached to the R.H. and L.H. fuel level sender assembly cover plates as shown in the figure.
If the R.H. sender date code is less/smaller than "01301", replace the complete assembly with a new fuel sender kit indicated below by model year. If the
L.H. sender date code is less/smaller than "32791", replace the existing fuel sender sensor and strainer with those components contained in the applicable
sensor and strainer kits shown below by model year.
