C1525 — Steering Torque Sensor Zero Point Adjustment

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

About C1525

C1525 is a manufacturer-specific chassis diagnostic trouble code recorded for Toyota vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1525 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.

C1525 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 C1525 is stored when the Power Steering ECU determines that the steering torque sensor zero point is not properly calibrated or is missing. The zero point is the reference signal value the torque sensor produces when no steering input is applied, and the ECU uses this baseline to work out the direction and amount of assist to deliver as the driver turns the wheel. Because the assist calculation depends on an accurate baseline, the zero point must be relearned with a scan tool whenever the torque sensor, steering column, or ECU is disturbed. C1525 sets when that value has not been learned, ...
