P0460 - Fuel Level Sensor A Circuit
Description:
The powertrain control module (PCM) monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified fuel fill percentage in the fuel tank.
Possible Causes:
- Empty fuel tank
- Fuel pump (FP) module concern
- Incorrectly installed fuel gauge
- Damaged instrument cluster
- CASE GND circuit open
- FLI shorted to VPWR
- Overfilled fuel tank
- Damaged fuel gauge
- FLI circuit open
- FLI circuit shorted to CASE GND or PWR GND
- CSE GND shorted to VPWR
- Damaged PCM
Diagnostic Aids:
Monitor the FLI and FLI V PIDs in key ON, engine running. A concern is present if the FLI PID is at 25% fill and the FLI V PID is less than 0.90 volt with a non-matching fuel gauge or the FLI PID is at 75% fill and the FLI V PID is greater than 2.45 volts with a non-matching fuel gauge.
Application
Key On Engine Off
Key On Engine Running
Continuous Memory
Ranger
GO to Pinpoint Test HX .
All others
Refer to the Workshop Manual Section 413-01, Instrument Cluster for fuel level indicator diagnosis.
Your vehicle has coil on plug ignition system , these systems can burn out coil driver (transistor ) inside the PCM - engine computer . Not replacing sparks before they get too worn , can cause coils to short out inside sending 20,000 volt's into the computer . You probably need a new computer , if so it has to go to the dealer to be programmed . You got screwed . Your best bet , take it back an get your $500 back. That's why he sold it so cheap .
