Please I change my ball joint on Chevrolet equinox 2018 yesterday
When the Mechanic finish the job I put the diagnostic machine in the code
onComment for C0545 Chevrolet Code – Steering Wheel Torque Sensor-
Changing a ball joint shouldn’t directly cause a C0545 code, but the timing suggests something happened during the repair that affected the steering system or its sensors.
On the 2018 Equinox, C0545 means the steering wheel torque sensor is seeing a value that’s out of range. That sensor is built into the electric power steering unit, not in the suspension. Common reasons it shows up after suspension work include:
• The steering wheel was turned too far while the vehicle was lifted, putting stress on the steering rack.
• The intermediate shaft or steering column was moved or twisted while the control arm was out.
• A poor connection at the electric power steering motor or torque sensor connector.
• Low voltage during the job from leaving the doors open or battery weakening (EPS is sensitive to voltage drops).
• Alignment is off enough to confuse the steering angle/torque calibration.First thing to do is clear the code and see if it comes right back. If it does, check the wiring connectors on the electric steering rack — make sure nothing was pulled, stretched, or left loose.
If everything looks good, the vehicle may just need a proper alignment and steering angle sensor reset after the suspension work. This is common on modern GM vehicles.
If the code returns immediately even after a reset, then the torque sensor inside the rack might be damaged, but that’s the last thing to suspect. Usually this code after a ball-joint job is caused by a connector that got tugged or the system being out of calibration.
