Intermittant ABS/TRAC lights come on
1994 Volvo 850 Turbo OBD2 certified,Intermittantly ABS/TRAC control lights come on while driving,sometimes on for a long time,sometimes off for a long time.
I have cleaned ABS sensors and all resistances are approx same.I had another 94 850 turbo given to me(all ABS/TRAC lights off and tried swaping ABS/TRAC control module & relay next to it to no avail.
ABS codes in this order:
1)444 No power supply to valve hydralic unit
2)211 LF Sensor
3)213 LR Sensor
4)141 Pedal Sensor
5)214 RR Sensor
6)142 Brake light switch
Anybody have any ideas to a fix?
Also engine idles rough in Drive but is nice and smooth off idle.Has new cap,rotor,wires & spark plugs.
Compression a little low on 1 cylinder & lifter noise comes & goes.Valve burning out maybe??
Thanks
Rick
