I have an '93 Grand Marquis that has an occassional flashing of the Anti Lock Brake Light (also has Traction Control). The Code is "66 Pressure Switch Circuit Fault." Is there only one repair or do I have to test various parts (most are expensive)? What is the faulty part (Pressure Switch) or is this a general code. If it is the Pressure Switch, where EXACTLY is it?
have the same problem?
