    Default Mx83 Cressida prblems

    Hi guys i have a problem with my Cressida still has the 7mge motor in it and when i start the motor up and rev it over about 1800rpm the engine warning light comes on, if i turn it off again and restart it will go out then i can drive it down the road and wont come on as long as i dont rev it over 1800rpm.Car is still running as normal and have had a diagnostic check done and it saying it is the speed control sensor .Has anybody had this type of problem before and how to fix.I have had it to a auto elect but could not help as needed circuit diagram layout of speedo circuit.
    thanks any help

    Is it speed sensor no1 or no2 ? They have separate codes.

    Is it a Grande, series 1 or 2?
