So my Mother calls me today and says that her SES light came on 3 days ago and she had the parts store pull the codes for her.
P0463 Fuel Level Sensor Circuit High Input
She drives a '05 v6 vert that is still in factory condition (no modifications at all).
Engine idles fine
Engine temp runs normal
No bucking or hesitating at speed.
No heavy smell of fuel at exhaust or anywhere on fuel system.
Fuel guage in cluster functions normal.
What would cause this problem? Or is it just a fluke??
I told her to bring it by tomorrow and I will clear the code for her. Then have her drive it for a few days to see if the code gets thrown again. That's the only thing I could think of to do.
My OBDII code reader pulled no codes, yet the engine light was still on. I disconnected the Batt. and waited 20 min. then reconnected. The engine light is no longer on and I told her to keep an eye on it and let me know if it comes back.
Well it's been a few weeks since I reset her computer. She switched to a brand of gas with cleaner additives, as recomended, and the light/code has not come back.
