Code B664 - Cruise Acceleration
NOTE:
If any code(s) higher than "B666" are also set, go to that code(s) first.
This code will set and disengage cruise control if engine exceeds 5000 RPM. This could occur on slippery pavement, on extended wide open throttle acceleration or from some mechanical problems. Under these conditions code setting is normal and driver should be advised. Clear code and road test vehicle to verify normal operation.
