C1B00 on Nissan
Steering Angle Sensor Fault
C1B00 on Nissan vehicles indicates steering angle sensor fault. Au7o has documented this code across 1 Nissan model — most commonly on Sentra. C1B00 is a manufacturer-specific chassis code (commonly Ford) indicating the power steering or stability control module detected a fault with the steering angle (steering wheel position) sensor. This sensor tells stability control and electric power steering where the steering wheel is pointed, which is essential for traction/stability control and assist calibration. When the signal is missing, erratic, or fails plausibility checks, the module sets this code and may disable stability control and reduce or alter power steering assist. Steering still works mechanically, but related driver-assist systems may be limited. Typical repair costs on Nissan range from $600 to $1,400, depending on the specific model and root cause.
Common Causes of C1B00
- •Faulty steering angle sensor / clockspring assembly
- •Calibration not performed after alignment, battery, or steering service
- •Damaged or corroded sensor wiring/connector
- •Erratic or implausible sensor signal vs. other inputs
- •Power steering control module fault
- •Low system voltage or poor ground
- •Worn or damaged steering column components
C1B00 on Nissan by Model
Nissan Sentra(1 issue)
- Forward Emergency Braking (AEB) Phantom Activation2015-2021
Sentras equipped with Nissan's Forward Emergency Braking / Automatic Emergency Braking apply the brakes hard for non-existent obstacles ('phantom braking'). The Bosch radar module behind the front grille (sensor assembly p/n 28438-5UD0A) produces false positives, frequently triggered by overpasses, bridges, railroad tracks, parking-garage walls, and metal grates. Nissan disclosed 1,233 related consumer complaints to NHTSA for the Rogue/Rogue Sport/Sentra, including dozens of minor collisions and injury allegations, and the defect is the subject of class-action litigation.
