The cost to diagnose the C1023 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
During normal operation the Power Steering Control Module (PSCM) continually monitors and adjusts the steering efforts based on torque sensor inputs to enhance the steering feel. Adjustments are made based on the torque sensor inputs to reduce the effect of pull or drift that may be experienced when driving on roads with a high degree of camber or induced by outside influences. If the level of compensation required to keep the vehicle driving straight ahead exceeds a predetermined level a DTC will be set.
