Indicator light came on steady for a couple of days then started flashing last night. I have checked the fluid level several times and it is OK, the lights are all working and the brakes work well. Would the pressure sensor going bad cause this type of indication or should I look at another problem?

If you haven't already, check for mil codes. See if anything shows up? You place a jumper wire between the A & B terminals of the datalink connector, turn the key just till the dash lites come on, no further. The mil starts flashing, you count the flashes to get the code. Your looking for two digit codes. I'm not exactly sure which indicator lite is coming on? The mil is the only one that flashes, as far as I know?
