On my buddies rock crawler which has 94 chevy 350 with a th350 trans. and a 1227747 ecm, we keep getting error code for VSS. My question is that we did not hook this sensor up to the ecm so I would expect to get an error code, but what effect is this having on the ecm? The crawler runs but occassionally dies for no apparent reason. So I am just wanting a little more info as to wether or not it might have anything to do with this sensor not behing hooked up. Also, does this error code casue the computer to go into "limp" mode? What does that mean?
Thanks for any help on this.
