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. Typical repair costs on Lincoln range from $200 to $2,800, depending on the specific model and root cause.
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

Lincoln Aviator(1 issue)
- Air Suspension Fault - Vehicle Stuck Low or Will Not Raise (SUMA Service Mode)2020-2023
Aviators with the optional Dynamic Air Glide suspension display 'Suspension Fault' or 'Drive Malfunction' messages and may sit low at one or more corners, fail to raise, or refuse to enter Entry/Exit mode. DTCs B1041 and U2100 are stored in the Suspension Control Module A (SUMA), which has entered a diagnostic 'service mode'. Often triggered by improper jacking (without Service Mode) or after suspension work. Ford addressed in SSMs 48792, 50930, and 51621.
