P2067 code……. But I changed the level sensor
Need some guidance on the issue. Gauge was fine until my fuel pump went out! Replaced the whole pump assembly, internal lines, and crossover tube. When I first started, only half tank showing on fuel gauge after fill up. Drove for 30 min, fuel gauge dropped to zero, service fuel system error and P2067 code. Just replaced the B level sensor and the problem remains. Ohmed out both sensors, old one was fine but I had the new so went ahead and replaced. What could the issue be since everything is now new and the problem wasn’t there until the fuel pump was replaced? The only connections were the one above the passenger side where the exhaust pipe connects to the axel back. Am I just missing a connection somewhere possibly?

If you'd left something disconnected, you'd see an off-scale high voltage code P2068.
I'd start by confirming the sensor resistance as installed. Unplug the connector you mentioned. On the fuel tank side, measure the resistance between pin 3 (light blue, right fuel tank signal) and pin 5 (low reference). If it's less than 40Ω, there's your problem.

@torquetube Thanks. I’ll try that. Pretty sure I ohmed it out before connecting it but will give it one more shot. By the looks of your reply, I may be chasing down a ground.

check that. Did you change it with the right year sender? GM in all its wisdom swapped ohm direction for full/empty halfway through the C6 Model.

The sensor resistance may have seemed sensible on the workbench, but now that it's installed something is wrong. You have to isolate the fault by disconnecting plugs and checking resistances.

The wrong sensor won't throw a P2067. A disconnected plug won't throw a P2067. P2067 means that the reference voltage supplied by the ECU is being pulled down too close to ground—either by a sensor circuit with resistance less than 40 ohms, or by a short-circuit to ground.

I had the same problem. Month after install did the same as u. I was so pissed chasing that stupid problem i just went by mileage.Few months went by. I wasn't even looking at iit anymore. Fill up and gauge caught the corner of my eye and the gauge was working. So far its been months and still working. This is my experience.

Wow!! I can only hope that happens as well!!! Glad yours turned out for the best!
