B2741 Ford Code - Sensor Cluster Defective

Quick Answer

The yaw rate sensor, roll rate sensor, lateral accelerometer and longitudinal accelerometer are contained in one module called the stability control sensor cluster. Common causes include Faulty Stability Control Sensor Cluster, Stability Control Sensor Cluster harness is open or shorted, Stability Control Sensor Cluster circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B2741 Ford Description

The yaw rate sensor, roll rate sensor, lateral accelerometer and longitudinal accelerometer are contained in one module called the stability control sensor cluster. The sensor cluster measures the vehicle acceleration, roll rate and yaw rate, then sends the signal through a secondary, dedicated controller area network (CAN2) bus to the ABS module. The ABS module compares the information from the sensor cluster to information it receives from other sensors (brake pedal input or steering wheel rotation sensor) to determine how valid the information is and to determine if a roll-over event is about to occur.
The ABS module provides power to the sensor cluster and ground. The sensor cluster and the ABS module communicate. An open circuit or a short to power or ground on any one of these 4 circuits will cause the ABS module to set a DTC. Also, if the sensor cluster is not mounted in the correct position, with the electrical connector facing the passenger seat, the ABS module will also set DTCs.

Code Tech Notes

This is a general failure of the sensor cluster. An open or short to power or ground in one of the 4 sensor cluster circuits will cause the ABS module to set this fault. This DTC will also set if the sensor cluster is reporting information that is out of the normal range or operation, if there is an internal failure of the sensor, if the sensor cluster either has not been calibrated or lost the calibration or if the sensor is missing or mounted incorrectly.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the B2741 Ford code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
