Fuel sender
I’m convinced my fuel sender sensor went out a couple of days ago because my car is still reading over half a tank of course this doesn’t stop me from driving the car so I’m not too worried, but I need to fix it.
I’ve looked at other posts and checked fuses related to fuel, checked my connections(visually), and checked the hidden menu. Maybe not the best photos, but they get the point across that the sender is getting like 0 power. Is this a reasonable diagnosis for the issue or do I need to do something else? Thanks in advance. |

Questions: 1) When you fill the tank, what does the gauge show? 2) Does the Left Tank Sender still show ~ 51 Ohms using Hidden Menu 6.02? OR 3) Does Left Tank Sender NOW show ~ same resistance as Right Sender (with full tank)? Your Jet Pump is designed to pump fuel from the Left Half of Tank (where Left Fuel Level Sensor/Float is located), to the Right Half of Tank, where the Fuel Pump and Right Fuel Level Sensor/ Float are located. Your Fuel Level Gauge on Instrument Cluster displays the TOTAL fuel reported by the TWO Level Sensors. So if the gauge reads nearly full after you fill up, BOTH Level Sensors are working. Hidden Menu 6.02 would confirm that. If the Left Level Sensor never reads more than 51 Ohms, then either the float doesn't 'float' anymore, the float arm is stuck in Down position, or there is an Electrical issue with that Sensor signal as received by the JBE Module. In any event, the Good News is that your Right Sensor (where the pump is located) is still working, so the "Last Half Tank" can be monitored. George |

The tank is hovering between half and 3/4. The problem is that it fluctuates up and down between those ranges and it hasn’t gone down past half in like a week and a half. The sender hovers at like 50 ohms tho

I went ahead an filled it up and the 6.02 showed that they both were reading about 980 ohms(took pictures if you want). The tank on the left though was finally showing fuel tho
