Fuel Level Sensor B Circuit Intermittent
Fuel-level sensor B signal jumps or drops out intermittently — usually a corroded sender or wiring. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
