C1A04 on Nissan
Front Right Height Sensor Fault
C1A04 on Nissan vehicles indicates front right height sensor fault. Au7o has documented this code across 1 Nissan model — most commonly on Sentra. C1A04 is a manufacturer-specific chassis code (documented on Nissan/Infiniti applications) indicating a fault with the front-right height sensor. This sensor measures ride height at the front-right corner and feeds systems such as auto-leveling suspension or automatic headlight aiming. When the module sees an invalid or out-of-range signal, the dependent feature is disabled and a warning may appear. Because it is a manufacturer code, confirm the exact application against the factory service manual. Typical repair costs on Nissan range from $250 to $1,800, depending on the specific model and root cause.
Common Causes of C1A04
- •Faulty front-right height sensor
- •Damaged sensor link/arm or mounting
- •Damaged or corroded wiring/connector
- •Water intrusion at the connector
