Specs on my car:
-1992 with stock ECU
-Cruise control works
-Speedometer/Tach works
-ABS works (last I checked a few weeks ago)
Recently, my CEL has started to illuminate briefly and randomly upon start-ups and while driving (code 42, vehicle speed sensor). . not sure if it has anything to do with it but while driving it seems to happen after being on and then followed by a sudden off throttle (enough that the blow-off sings), a second or more after that the CEL illuminates and goes away.
I replaced the sensor for the cruise control years ago and it works fine (not entirely sure if this is even tied to the ECU anyways, if it was why didn't it do this before replacing it?), speedometer works fine too. Would the hub sensors for the ABS cause this? While searching for a possible cause, I recall seeing a mention of these somewhere and to check them with an ohm meter.
I haven't tried disconnecting the battery yet as I was hoping it would just stop (and mostly because I don't want to reset my radio) but it has been a few days now. If any of you have experienced this, what do you suggest?
Thanks in advance
