    SAAB / 93 /2001 /2.0 turbo/ Intermittant speedo? Archived Message

    Posted by Steve Pearman on October 14, 2008, 9:20 pm

    Been trying to get to the bottom of this one. Speedo only work occasionally for a few seconds but only if i drive over rough ground and road humps. ABS system tests ok and live data looks good with 4 equal wheel signals, tried 2 ABS control modules thinking because the speedo signal is coming via the ABS it must be an internal fault, but no change. Had tech 2 connected to check out the speedo head at various settings and all ok. Spoke to a SAAB guy today he said he had a simular problem which turned out to be the n/s/r sensor which is the one that also drives the speedo pulse. If i havent got any ABS problems from sensors then how can i have a speedo problem using the same signal. Any advise would be appreciated.

    Thanks Steve.
