C1719 — Left Front Centre Sensor Circuit Fault

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

About C1719

C1719 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 C1719 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.

C1719 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 C1719 relates to the left front centre ultrasonic sensor of the front parking aid system, one of the inner pair on a four sensor front bumper. This code is set when the Parking Aid Module (PAM) receives a response from the sensor but the signal is invalid, erratic, or outside expected parameters, which distinguishes it from a hard open or short circuit failure. The module evaluates each sensor during its self test and continuously while the system is active, and it flags this fault when the left front centre sensor cannot reliably transmit or receive its ultrasonic pulses. When the code is...
