Default Re: 2019 Onward Kohler Issues

just an FYI. There is a TSB for this issue. My cart had the same issue and the dealer replaced the 02 sensor and reprogrammed the computer. I am not sure this completely resolved the issue because it still happens from time to time. I believe its a result of poor quality gas and the issue only shows up after the cart has sat for about 1-2 hours and the motor is still warm/hot. The cart will drive as normal until it worms up to full operating temperature and as soon as the computer switches from an open loop program to the closed loop program it will start sputtering.

The reprogramming of the computer has made our cart run a bit richer on gas and we have noticed we burn through more gas than before the reprogramming (we live on an island and the cart is our primary mode of transportation).

When this issue show up, I have been able to resolve it by turning the ignition off for a few min to allow the computer to reset. You'll know when that happens because the yellow check engine light will illuminate for a few seconds when the ignition is turned back on. If it doesn't illuminate, you need to wait longer before turning the ignition back on.

If resetting the computer doesn't solve the issue, disconnect the 02 sensor at the connector. This will force the computer to run in the open loop program mode and the yellow check engine light will come on but the cart will drive normally. Once you park the cart for the night or at least 8 hours to cool off, reconnect the 02 sensor and it should work as is supposed too.

Hope this helps.
