We have here a 1990 RRC 3.9i GCC spec (low tech, no code display)
Have no Owners manual to read what this means.
We are talking here about the light with the exclamation mark and yellow/amber colour.
Had the same light before and disconnecting the battery solved the issue for a while, but now its back...
The light came up again a few times and I just reset all by diconnecting the negative on the battery.
BTW this model is not equipped with traction control or cats (therefore no o2 sensors)!
today something new came up - the light got on while driving.
what would be your next guess to check?
So guys put the thinking caps on and help me with this!
For a start:
Which sensors are checked from the ECU at the start process?
Which sensors play a role after a while driving?
Why I am asking - after reseting the car the light comes up while driving and moderate throttle. Tried also reving the engine stationary and it didnt came up.
