Code p00c6

[Alanggg]

Hey guys so today I was driving home and I only had 4 miles to empty took an exit to go pump gas but all of the sudden car cut power and died . I thought I ran out of gas and got a jugg and pumped 93 on it but now car won’t start and got the code p00c6 . Car is Lund tuned only mods it has is headers , has anyone ever had this problem?

P00C6 is rail fuel pressure fault. Sounds to me like your miles till empty are off by (4)

Try cycling the car on and off without cranking to get the fuel back through the system. Or you may need to bleed out the air at the rails.

If you did get it running, the code should clear after a few miles.

Most likely if the OP's fuel gauge is off by 4gal +/-, then OP might need to adjust the AFE Bias calibration of the cluster. It's been discussed on here elsewhere as others have found that the S550 MPG readings are not accurate or in some instances not being calculated correctly in both the Analog and Digital clusters. One can confirm this if they did the old fashioned MPG pencil to paper (or Excel sheet) math.

To adjust the AFE Bias, you first need to access Engineering Mode; the below links demo how to access EM.

If you have a 2015-2020 with the ANALOG gauge cluster, you should be able to enter the “Engineer Test Mode”.

If you you have a 2018-2020 with the DIGITAL cluster, you should be able to access the same test mode found here:
