B1041 on Lincoln
Oil Level/Temperature Sensor Circuit Fault
B1041 on Lincoln vehicles indicates oil level/temperature sensor circuit fault. Au7o has documented this code across 1 Lincoln model — most commonly on Aviator. B1041 is a manufacturer-specific body-network code that, on most vehicles that use it (notably some Mercedes-Benz and GM applications), points to a fault in the engine oil level/temperature ('thermal oil') sensor circuit or its wiring. The control module monitors this sensor and has detected a signal that is out of range, open, or shorted. It generally does not affect drivability but means the oil-level/condition reading reported to the dash may be unreliable. Because the exact meaning varies by maker, confirm against your vehicle's service data.
Common Causes of B1041
- •Faulty oil level/temperature (thermal) sensor
- •Damaged or chafed sensor wiring (often near a harness bracket)
- •Corroded or loose sensor connector
- •Low or contaminated oil affecting the sensor reading
- •Open or short in the sensor signal/ground circuit
- •Faulty control module receiving the sensor input

- Air-Suspension Fault B1041/U2100 After SUMA Diagnostic Service Mode2020-2023
Some 2020-2023 Aviators equipped with air suspension may display a Drive Malfunction and/or Suspension Fault message with DTCs B1041 and U2100 stored in Suspension Control Module A (SUMA). Ford SSM 51621 says this bulletin-defined condition can occur when SUMA enters diagnostic service mode after an on-demand self-test following suspension diagnosis or repair. It does not identify a leaking air spring, compressor, height sensor, or solenoid as the cause of these two codes.
