C1740 — Right Front Centre Sensor Circuit Failure

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Ford

About C1740

C1740 is a manufacturer-specific chassis diagnostic trouble code recorded for Ford vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1740 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1740 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

DTC C1740 is a manufacturer specific chassis code reported by the parking aid module on Ford vehicles, including the Falcon and Territory, and similar codes in this range are used by other manufacturers for their parking sonar systems. The front bumper carries multiple ultrasonic parking sensors, typically outer and centre sensors on each side, and the module monitors each sensor circuit for correct electrical operation and a valid response signal. C1740 is set when the module detects a general circuit failure on the right front centre sensor, such as an open circuit, a disconnected or unrespo...
