I have a foreman 500 that is blinking 13 times for tps. The carb looked rough, so I ordered a new carb from Honda with a new tps on it. I installed the carb and it still blinks 13 times. Honda already broke the screws off, but I easily backed them out and adjusted the tps by ohm meter. I cleared the codes, but still 13 blinks and it will not shift. Does anyone have any advice or anything else to check?​

Unplug you ECU under the front plastics, slather dialectic grease on the connections, and hook them back up. If your TPS isn't bad and you're still getting a TPS code it points to a bad ECU. In my case the plugs had some gunk in them and werent making a good connection.

I have also put a new cdi on the 500. I will try some grease on it to see if it helps.

Yeah, mine was a little touchy at first. The 06 I have in my sig had been sitting up for a couple of years when I got it. I checked the TPS, found it tested good with my ohm meter, so I put dialectic grease on the ECU plugs and that stopped the error code for awhile, but then it would come back. I tried a different ECU and it still popped up intermittantly, so I put the original back on, again packing grease in the connections. It went away and hasn't come back, so only thing I can think of is one of the connections wasn't getting good connectivity, and plugging/unplugging it over and over again got ride of whatever crud/corrosion was causing the bad connection.

Make sure you put grease in where your plug hooks up to the TPS......

I have checked all connections. I cleaned the electrical plugs and greased them. New CDI, new speedometer display, and new carb with new TPS, but I still get 13 blinks on the dash. Does any one have any other ideas what the problem could be. I clear the codes, but it starts blinks as soon as it clears. When I turn the key on, if I press the shift button quick enough, it will shift, but then start blinking and will not shift back. HELP Please!

Wow. Mine is a foot shift so it would still shift, just had that annoying blinking.

Manual says check TPS, if TPS checks out it point to bad ECU.

If you've replaced both I got nothing.

That's where I am. Very confused. I don't know what to do next. Maybe I will adjust the tps and play with it to see if that helps.

Did you ever get it fixed? I am having the same exact issues. TIA
