The Fuel Level Input is checked forout of range values, opens and shorts. If the FLI signal is stuck, a P0460 is set. The ECM calculates the amount of fuelbeing consumed by accumulating fuel pulse width. If the there is an insufficient corresponding change in fuel tank level,a P0460 DTC is set. Finally, the Fuel Level Input is checked for noisy readings. If the FLI input changes rapidly, a P0461DTC is set.Fuel Level Input Check Operation:DTCsMonitor executionMonitor SequenceSensors OKMonitoring DurationP0460 – Fuel Level Input Circuit ErraticP0461 – Fuel Level Input Circuit StuckP0462 – Fuel Level Input Circuit Low (short to ground/open circuit)P0463 – Fuel Level Input Circuit High (short to power)continuousNoneFLI errors12.7 sec for circuit tests, 10 sec for noisy test, 120 miles for stuck testTypical Fuel Level Input check malfunction thresholds:P0462 (Fuel Level Input Circuit Low): < 0.01 V ratioP0463 (Fuel Level Input Circuit High): > 0.9902 V ratioP0460 (Fuel Level Input Stuck): < 2L or > 30 L change after o7.5 L has been consumed.P0461 (Fuel Level Input Gradient): > 0.5 L change over a 660 msec sample periodCONTINENTAL REVISED: SEPTEMBER 17, 2010 PAGE 29 OF 111
