What Does C1741 Mean?
The right front center parking sensor circuit has a fault condition, indicating the sensor is sending signals outside the expected range or behaving erratically. Unlike a complete failure (C1740), this code suggests the sensor is partially functional but unreliable. The parking assist system may give intermittent false alerts or inconsistent distance readings for the right front zone.
Common Causes
30%
Parking sensor partially obstructed by dirt, ice, mud, or paint overspray
25%
Sensor degrading internally — intermittent ultrasonic transducer fault
20%
Intermittent wiring connection — loose pin, cracked solder, or frayed wire causing signal noise
15%
Sensor not properly seated in its bumper mounting grommet, causing resonance or vibration interference
10%
Water intrusion into the sensor housing causing intermittent internal fault
Diagnostic Steps
1
Clean the sensor face thoroughly — remove any dirt, mud, ice, road salt, or paint overspray that may be blocking or interfering with the ultrasonic signal.
2
Verify the sensor is properly seated in its bumper grommet — it should be flush with the bumper surface and snug in its mounting. A loose sensor can vibrate and produce erratic signals.
3
Place your finger directly on the sensor face while the system is active — you should feel a slight vibration/clicking indicating the sensor is transmitting. Compare to adjacent sensors.
4
Inspect the sensor connector for intermittent contact — wiggle the connector while monitoring live data on the scan tool. Fluctuating readings indicate a connection issue.
5
If cleaning and connector checks do not resolve the fault, swap the sensor with an adjacent working sensor to determine if the fault follows the sensor or stays at the wiring position.

The most common cause of C1741 (Right Front Center Sensor Circuit Fault) is: Parking sensor partially obstructed by dirt, ice, mud, or paint overspray
Typical repair costs for C1741 range from $30 to $250, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle is safe to drive. The parking assist may give intermittent false alerts or incorrect distance readings for the right front area. Do not rely solely on the parking sensor system for close-quarters maneuvering. This is a convenience issue with no impact on vehicle drivability.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1741 to identify the root cause.
