![]() "Lifetime" on a filter? Anyways, he also told me that his senior tech said that don't ever replace fuel filters and that it would require them to drop the fuel tank. It has a "lifetime" use:question: what ever that means.dunno. About 30 mins later, he called back and basically told me it doesn't need to be replaced (ever). After relaying my question to the Service department, he stated that he will need to ask his "senior tech" and would call me back. So after that confusing conversation, he offered to direct me to their service department to verify if I am required to replace the fuel filter at the 60,000 mile service interval. He also went on about his servicing guys have never asked for a fuel filter for any servicing of VX Subarus. The issue is when I called my local Subaru dealership (parts shop) to start ordering everything, the gentleman in the parts shop stated I shouldn't need to replace the fuel filter (unless I was experiencing something that would indicate a problem). I understand the following will need to be replaced If the resistor substitution test is okay, and before trying to pull the sensors out of the tank, it might be worthwhile trying this method.I plan on doing the 60,000mile service to our 2013 VX. If the car is at the dealer now, I would hope they would be going through it in this sort of manner.Īs has been noted, there have been cases of the sensors developing problems due to deposits that fuel system cleaners, such as Techron, might be successful in clearing. The sensors would have to be removed from the tank and manually varied to see if the resistance changes over the proper range. Unless the actual amount of fuel in the tank is known, measuring the resistance of each sensor might not be meaningful. But if the test is good, then the problem is with one or both sensors. If the test isn't good, then given that there's a new gauge, the wiring is the next suspect. This might happen during these tests, but it's only because there isn't a corresponding air flow.) If the change in the resistance doesn't correspond to the calculated fuel used, it can trigger a trouble code such as a P0461. (Note, the OBD system monitors the resistance value, or more accurately, the voltage on the sensor wire, and compares it to the fuel use it calculates from the amount of air taken in by the engine (measured by the MAF). Or, if a 0-100 Ohm variable resistor is available, it can be connected between the black with blue stripe wire (pin 1) of the harness connector and ground, and the resistor control varied slowly through the full range. And, same with the 95 Ohm resistor the gauge should read E. Key On, the gauge should read somewhere in the middle. Turn the key OFF, connect the 45 Ohm resistor. (This is, in effect, substituting the known resistor in place of the two sensors.) Turn the ignition key ON. The test would be done by connecting known value resistors, say, of 2 Ohms, 45 Ohms and 95 Ohms, between the harness connector pin with the black with blue stripe wire (pin 1), and a good ground. (The top of the pick-up and sensor assembly should be accessible with the bottom of the rear seat removed, and an access panel removed.) There should be two wires, a black with blue stripe (pin 1), and a blue (pin 2). ![]() To test the system other than the sensors, disconnect the two pin connector R59 at the left (driver side) sub-level sensor. These values aren't any help if the actual level in the tank isn't known. I found the sensor specs (I was a bit off the total is 92-96 Ohms): (The question of whether the gauge goes closer to E when the level in the tank should be fairly low hasn't been tested.) New cluster that didn't change the fundamental symptom, as I understand it, namely, that the gauge doesn't go to F when the tank is filled. ![]() I'm also somewhat unclear on what's happening. ![]()
