JD 110 TBL computer code

L225 · Jul 14, 2012

I have a JD 110 TBL and I'm getting a computer code flash of 3 shorts and 1 long. Any ideas on this one ? The tractor was purchased a number of years ago by me with about 100 hours on it and I only use it as a "toy" on my small hobby farm. I have put about 600 hours on it and always maintained it well. (oil, filters, etc.) It has been kept inside when not in use. I called the dealer and they were no help !

Thanks for your time and I hope someone can help!

The code is for the throttle position sensor. Either the sensor is bad, or more likely it needs adjustment. These are the voltage specs. Specification:
Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . 5.0 ± 0.2 volts
Low Idle Position Signal Voltage. . . . . . . . 0.4 - 1.0 volts
High Idle Position Signal Voltage . . . . . . . 3.2 - 4.5 volts
Be sure to use a digital voltmeter to check. Analog meters can damage the controller. The wires all need to stay connected when testing. Back probe the connector with a needle or pin to make contact with connector.
