Question about 1992 Subaru Legacy

Fuel gauge/temp gauge not working

1992 Subaru Legacy 2.2L AWD The fuel gauge and the temp gauge are both bottomed out (the needle is not rising at all). We just changed the CPC Solenoid, which was diagnosed as needing replacement from the check engine light code. The gauges stopped working after completing the replacement. Could we have messed up a wire/wires that control the gauges? Thanks, Richard

There are two sensors, one for ECU temp. readings with two pin connector and other one with only one wire, which has been probably disconnected when you replaced the CPC solenoid - very close position.

ARE U SURE THE GAUGE IS ACURATE? THERE IS A TEMP SENDING UNIT USUALLY ON THE SIDE OF MOTOR BLOCK WHICH SENDS SIGNAL TO GAUGE. I WOULD CHANGE THAT FIRST BEFORE DOING ANYTHING ELSE. PART IS NO MORE THAN 20$.

Subaru legacy b4 fuel gauge read empty when full?gauges jump about too


You have a fuel level sending unit that is not working properly. It is located inside the fuel tank.

Also, when you ask for help with your vehicle it would be very helpful if you could mention WHICH "Legacy" we are talking about. It seems that Subaru got "stuck" on the Legacy name - there are actally 9 choices for "Legacy" just for your model year. (see list below) There are also 2 different engines available for that year a 2.2L and a 2.5L.

Gauge registers 3/4 full when full, then needle slowly goes down to empty. Flucuates between empty and 3/4 full while driving.


hi its either the fuel gauge playing up in the dash up or the fuel sender on the fuel pump in the tank

Ok so my engine is making a ticking sound in the far back what is it?


My guess is that it's a lifter. It's best to talk with a dealership mechanic about the best course of action with your specific vehicle. Usually a engine will last a very long time with a lifter tick. And don't forget to always check for recalls on all the cars you own. Here is a couple I found for your call. In this case it has nothing to do with your ticking problem but for future reference its always a good idea to make sure it's not part of the problem.
Auto Recall Date:MAR 23, 1994 Vehicle Component: POWER TRAIN:MANUAL TRANSMISSION Estimated Vehicles Affected:31295 1992 Subaru Legacy Defect Summary:WHEN THE VEHICLE IS DRIVEN CONTINUOUSLY UNDER EXTREMELY COLD TEMPERATURES (-22 DEGREES F.) AND HIGH HUMIDITY WEATHER CONDITIONS, THE TRANSMISSION BREATHING (AIR) VENT CAN BE BLOCKED DUE TO MOISTURE FREEZING AT THE OIL LEVEL GAUGE. IF THIS OCCURS, PRESSURE INSIDE THE TRANSMISSION CASE WILL INCREASE AND PUSH OUT THE REAR OIL SEAL, CAUSING TRANSMISSION OIL LEAKAGE. THE LACK OF LUBRICATION CAN BURN THE INTERNAL COMPONENTS OF THE TRANSMISSION, CAUSE THE TRANSMISSION TO SEIZE AND THE VEHICLE TO COME TO A SUDDEN STOP. Defect Consequence:SUDDEN STOPS WITHOUT PRIOR WARNING CAN CAUSE VEHICLE OCCUPANTS TO BE THROWN AROUND THE VEHICLE AND CAUSE LOSS OF VEHICLE CONTROL WHICH CAN RESULT IN AN ACCIDENT. Remedy:DEALERS WILL MODIFY THE OIL GAUGE PIPE AND MODIFY THE OIL LEVEL GAUGE (DIPSTICK) OR REPLACE IT, DEPENDING ON THE TYPE OF DIPSTICK IN THE VEHICLE. Notes:SUBARU OF AMERICA, INC. Auto Recall Date:APR 01, 1992 Vehicle Component: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY Estimated Vehicles Affected:9500 1992 Subaru Legacy Defect Summary:A MISALIGNMENT OF THE REAR SEAT CUSHION LATCHING BRACKET REINFORCEMENT PLATE TO THE FLOOR REQUIRED A MACHINE TAP TO CLEAR THE OPENING FOR A MOUNTING BOLT. THE TOP OF THE FUEL TANK MAY HAVE BEEN PUNCTURED WHEN THE TAP WAS USED. Defect Consequence:THE PUNCTURE IN THE TOP OF THE FUEL TANK COULD CAUSE FUELTO LEAK, WHICH COULD RESULT IN A VEHICLE FIRE WHEN LEAKS OCCUR NEAR A SOURCE OFIGNITION. Remedy:INSPECT THE FUEL TANKS; REPLACE THEM IF THEY ARE PUNCTURED. Notes:SUBARU OF AMERICA, INC.

My subaru fuel gauge isn't working too.


You probably have a faulty sending unit which is mounted in tank..There is a access cover in the trunk which affords easy access to the unit and harness connector.at this point you can verify wiring and gauge operation by jumping connector which should read E....unplugged or open will make gauge go high...good luck

1992 SUBARU LEGACY WILL NOT START


Check to see if you have fuel at the fuel rail, if you do, check the injectors to see if they are working. You can use a noid light to see if they have any pulse.

How do you replace the fuel pump in 1992 2wd Subaru Legacy Wagon


  1. Relieve the fuel system pressure.
  2. Disconnect the negative battery cable.
  3. Remove the rear exhaust pipe and muffler assembly.
  4. On All Wheel Drive (AWD) vehicles, remove the rear differential assembly and the rear crossmember. You do not have AWD so this step is not for you
  5. Remove the fuel filler cap and drain the fuel into a suitable container.
  6. Remove the fuel filler pipe protector.
  7. Raise and support the vehicle safely on jackstands.
  8. Remove the fuel filler, air vent and delivery hoses.
  9. On AWD vehicles, disconnect the air breather hoses and evaporation hose from the pipes.
  10. Support the fuel tank with a floor jack or equivalent lifting device.
  11. Loosen the attaching bolts and lower the fuel tank slightly.
  12. Disconnect the fuel pump harness
