Do not throw parts at this problem. Follow this diagnostic flow:

translates to: "Steering Angle Sensor / Torque Sensor Zero Point Adjustment Uncompleted (Abnormal Current/Voltage)."

If your battery is older than 3 years, replace that first. If the battery is fine, pay a shop for a "Steering Angle Sensor Relearn." It takes 5 minutes and should cost less than $50. Do not let them sell you a $1,500 steering rack unless they have proven the sensor is actually dead. i--- Toyota C052f14

If "C052f14" is part of a VIN or a model code, here are a few general points that might help:

After any sensor or booster repair, you must perform a brake stroke sensor zero point calibration. With a capable scan tool: Do not throw parts at this problem

It might refer to a specific model or variant of a Toyota vehicle. Toyota has a wide range of models, and each can have specific codes used internally or by dealerships.

In severe cases, the entire electronic brake booster unit (including the pump and accumulator) is defective. This is an expensive replacement. Do not let them sell you a $1,500

A professional technician with a factory-level scan tool (like Toyota Techstream) will perform advanced checks. This includes reading the "Freeze Frame Data" to see the voltage the ECU was recording at the moment the fault occurred. They will also use a multimeter to measure voltage and resistance at the actuator connector's terminals, such as the critical BM (motor power) and +BS terminals, comparing them to specifications. Finally, they will test the resistance between the actuator's GND2 terminal and body ground to ensure a proper ground path.

A spilled coffee, a leaky sunroof drain, or a flooded floor pan can allow moisture to seep into the center console. The airbag ECU sits right on the transmission tunnel, vulnerable to humidity. Corrosion on the circuit board causes shorts.
