Start with the vacuum lines. Look for leaks. Is the brake peddle hard to press?

Frank Martin

no the brake is not hard to press. i was told that that its a sensor going or gone bad.


If you know what sensor is bad change it before it dies and leaves you stranded. Or get the trouble codes read so you know which one to replace.
