Clark C20SL:
Code 69

I have a clark c20 setting code 69.I checked wires and harness plugs. Replaced the accelerator pedal and still the same. Starts and idles but when I hit the gas pedal it sets the check engine light on. Any ideas.

Code 69 on the Woodward fuel system requires a software update to clear the code. Contact your local Clark dealer.
Or someone that has Moto Service and Moto Update and a Clark License key.

I tried a new throttle position sensor. Did not change anything. Also I checked with my meter that the signal is getting to the ecu but I don't know what wires to check if the signal is coming out to the sensor on the carb. I would love a wiring diagram. Haven't been able to find one.

Fault 69 is throttle pedal position does not match throttle position and derates engine speed. check for debris under pedal mechanism or seized pedal pivot. also confirm wiring ok.
Often the fault can be resolved by an SECM update.
