Thank you for allowing me to help you with this concern today. The two codes are both related to the ABS system and C1203 is the generic form code that basically states "Hey, we have a problem". The second code is more serious and is a malfunction for the brake booster signal sensor. So far, does this make sense?
Customer: replied 1 year ago.
Yes it does, and so your saying that the sensor is malfunctioning and I need a new sensor?
Expert:  Genchi Genbutsu replied 1 year ago.
The short answer is yes. There are two of these located on the brake booster itself and are sold as part of the booster (not separately). It takes about 2-3 hours of labor to replace the booster and then bleed the brake system. Of course the part is more expensive at the Toyota Dealer which runs about $800, I'm not sure about aftermarket prices as we never use them at the Dealer. Please ask more of me if needed as I am here to help and provide Excellent Service.
