Hello, my name is***** you trying to make repair yourself or just want to know what to expect at shop? Thanks.

Customer: replied 1 year ago.
I have to order the part and then someone will fit it
Expert:  Dan replied 1 year ago.

This could be a few different problems so testing will be required before knowing exactly what part has failed. Would you like testing instructions?

Customer: replied 1 year ago.
I can't do testing the part that is required is coded C1422. This is all I know
Expert:  Dan replied 1 year ago.

This code could be caused by a failed brake light switch, wiring, or brake actuator assembly. Without testing you would just be guessing which could end up costing alot of money to replace good parts just to find out wiring is the problem. Did shop ask you to order part or did you just check codes and trying to buy part to save money?

Customer: replied 1 year ago.
No the mechanic has checked the car and asked to get this part with code C1422 Master cylinder pressure sensor zero point high
Customer: replied 1 year ago.
He says I have to buy this part
Customer: replied 1 year ago.
Tell me if I have to get it online how can I do it and what to get and from where
Expert:  Dan replied 1 year ago.

I'd recommend bringing vehicle to a different shop or dealership. If mechanic gave you no information other then C1422 then I don't think he knows what he is doing. Like I said, this code can mean many things. Here are troubleshooting steps that mechanic SHOULD have done to figure out what part is bad then he would have been able to tell you actually part vs diagnostic code. I could easily give you a part number and link to some part but I don't want you to waste your money replacing good parts. Let me know if you have more questions, thanks.
