Symptom: P0462-FUEL LEVEL SENSOR NO.1 LOW When Monitored and Set Condition: P0462-FUEL LEVEL SENSOR NO.1 LOW When Monitored: Ignition on and battery voltage above 10.4 volts. Set Condition: The fuel level sensor signal voltage goes below 0.0196 of a volt for more than 90 seconds. POSSIBLE CAUSES FUEL LEVEL SENSOR VOLTAGE BELOW 0.0196 OF A VOLT FUEL LEVEL SENSOR (N4) FUEL LEVEL SIGNAL CIRCUIT SHORTED TO GROUND (N4) FUEL LEVEL SIGNAL CIRCUIT SHORTED TO THE (K900) SENSOR GROUND CIRCUIT PCM TEST ACTION APPLICABILITY 1 Ignition on, engine not running. t, read DTCs and record the related Freeze Frame data. With the DRBIII t, read the Fuel Level Sensor voltage. Is the Fuel Level Sensor voltage below 0.0196 of a volt? All Yes → Go To 2 No → Refer to the INTERMITTENT CONDITION Symptom (Diagnos- tic Procedure). 2 Turn the ignition off. t, read the Fuel Level Sensor voltage. Did the Fuel Level Sensor voltage change from below 0.4 of a volt to above 4.0 volts? All Yes → Replace the Fuel Level Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 3 3 Turn the ignition off. All Yes → Repair the short to ground in the (N4) Fuel Level Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 4 169 DRIVEABILITY - NGC |
