2000 Heritage engine light came on 2x while highway riding. Went off after about 2-3 minutes while riding. Engine runs well, no driveability issues. Engine light continues to give the "historical code" indicator. See attached video. To me it looks like code 12 which FSM says would be MAP sensor but it's a carb bike. What do you think? Speedo code check all shows "clr" CAL 03. Thanks in advance.

 

Your bike should have a MAP sensor on the intake. Pn 32316-99. Cost around $40. Check and clean the connector and if that doesn't clear the code, replace it.

 

Carb bike. No map sensor, no O2 sensors.

 

You were right, I was wrong. It does have a MAP sensor and it WAS bad. Thanks for the help.

 

The MAP sensor replaces the VOES of days gone by and allows ignition modules with much far better timing tables.
