Restricted Performance and Engine Failsafe

Hi all,
Crazy thing happened today. I braked on the freeway on a long trip and the VDP went in restricted performance and Engine Fail-safe. It did this approximately 9 times in about 7 hours. I tried both non-sport and sport modes. Does anyone know what causes this. I assume it is a sensor or something. I have had the car for 6 years and had no problems. Any help would be appreciated.

Has your CEL (check engine light) come on? If so you can read the codes (Autozone and others will do it for free). As Bob said, a good bet would be a P1571 code which implies a bad brake switch... But, it could also be a bad ABS module - somewhat common, and relatively easy to get fixed - but the codes will tell once they've been read.

Well, went to Autozone and got a P0121 which was the Throttle Body Sensor. I did some reading up on others who had the same problem. I ended up tightening up the TB cable as it had a lot of play in it. I also cleaned up the TB with TB cleaner, (though for 144,000 it was pretty clean). I also cleaned the electrical connection to the TBS. During the removal process, I also noticed that the tube that runs from the valve cover to the breather going to the TBS was shot, cracked due to heat and old age. I replaced that with 3/4" heater hose. Thus far, I have driven it around twice in town and I have not had any problems.
