What does the Nissan Sylphy fault code c1101 mean?

Fault code c1101 indicates excessive carbon buildup in the throttle body, which requires cleaning. Definition of throttle body: The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake manifold, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter at the top and the engine block at the bottom, it is often referred to as the "throat" of a car's engine. As one of the most critical components in modern fuel-injected engine systems, the throttle body's upper section connects to the air filter element, while its lower section links to the engine block. A vehicle's acceleration responsiveness is closely related to throttle body cleanliness. Regular throttle body cleaning can reduce fuel consumption and restore engine agility and power. Throttle body types: There are two main types: traditional cable-operated and electronic throttle bodies. In conventional engines, the throttle mechanism operates via a cable (flexible steel wire) or rod, connecting the accelerator pedal to the throttle linkage plate. Electronic throttle bodies primarily use throttle position sensors to adjust the opening angle based on engine demand, thereby regulating the air intake volume.
The Nissan Sylphy's C1101 fault code is typically related to the ABS system, possibly indicating a power supply issue with the ABS control module. I've personally encountered this situation where the ABS light on the dashboard illuminated, and the brakes felt strange while driving. There can be various causes, such as insufficient battery charge leading to low voltage, or poor contact/loose wiring in the circuits. ABS failure is particularly dangerous during rainy or slippery road conditions as it helps prevent wheel lock-up. I recommend immediately checking the battery's health to see if it's aged and needs replacement. If you're not familiar with electrical systems, it's best not to take risks—drive directly to a repair shop and have them use a diagnostic tool to read the specific fault data. Timely repairs can prevent bigger troubles. Remember to pay extra attention to the braking system during regular maintenance, as small oversights can lead to major accidents.
