[QUOTE="B5MECH, post: 340908, member: 6829"] I think I'm mis reading..........is the light on all the time? can it be cleared and stays away til it gets hot? The brakes I meant could be the booster diaphragm cracked :lol: AKA airleak...could be a air bypass valve, inlet gasket/o'ring as well Quote issue with my 98 5vz-fe dual fuel . First fault code was only Code 55 (no signal to ecu for crank revolutions between 1800-5600rpm- *open short in knock sensor circuit*knock sensor may be loose *ecu) replaced both knock sensors with new units also replaced bottom harness and did continuity checks from top hatness to escu no problem with wiring , next replaced ECU. Still the same . Did another codes check, same 55 code came back . Did you replace the crank sensor or not?....or have you only replaced a knock sensor?
