SERVICE ENGINE LIGHT P0462 - 2007 Nissan Quest 3.5 Minivan

P1460 Wide Open Throttle A/C Cutout Circuit P1462 A/C Pressure Sensor Circuit Low Input P0460....Fuel Level Sensor Circuit P0462....Fuel Level Sensor Circuit Low Input .take your pick first readings ford second set universal readings ...clear codes and see what happens but if quadro is coming on and going off then i suspect something wrong like a wiring plug loose ,maybe you need a new quadro or instrument panel although i rarely touch a focus of this year their bullet proof ,ok brakes and a timing belt ,regular service but these machines never give probelms with regular maintenance .

- Fuel level sensor harness is open or shorted
- Fuel level sensor circuit poor electrical connection
Low fuel level can trigger this code. Before replacing any parts try filling up the fuel tank and erasing the engine code. If the problem persist it may be necessary to replaced the fuel level sensor.

P0462 fuel level circuit,This is a need sensor for the ECM,to know the fuel volume in the tank.The sensing unit uses a float in the fuel tank which moves a wiper across a variable resistor,When this circuit is high or open or has a high resitance P0462 is set. To trouble shoot first inspect the connection the male to female connection.

typical mechanic
misfiring in injected engines is more from bad injectors that plugs , leads and coils
run a can or quality injector cleaner through the system and if it doesn't improve in a few miles , have the injector serviced

CODE PO462 FUEL TANK LEVEL SENSOR VOLTAGE LOW. CODE PO717 TURBINE SHAFT SPEED SPEED SENSOR NO SIGNAL. CODE PO722 OUTPUT SHAFT SPEED SENSOR NO SIGNAL. CODE PO500 VECHICLE SPEED SENSOR CIRCUIT MALFUNCTION. SOUND LIKE YOU HAVE TCM ECM PROBLEMS GETTING TOO MANY CODES. COULD HAVE LOOSE GROUND WIRE TO THE TCM AND ECM.

when was the last time you had your spark plugs changed
