I have a new Kubota L4701 with 14.5 hours. My engine warning light has come on and is constant. I have seen no blinking or heard any buzzers with this. Error codes are P0203 & P2148. Any ideas?

Sounds like its time for a carburetor cleaning and setting...the "black haze" is probably on your spark plugs too.. A too rich mixture will cause the engine to run hotter too...
Any GOOD small engine guy can take care of it.... install new spark plugs and get the carb taken care of.. you'll be fine!!

My light on warning buzzer ???????? Headlamps on warning chime or buzzer ? What year focus ? Probably not a fuse ! It's part of istrument cluster !

Jody, this is out of the manual
Warning light Comes on or blinks when: Comes on There is a malfunction in the 4-wheel drive system Blinks slowly The difference in wheel rotation is large

Buzzer is dead. As long as the lights don't stay on, keep driving. Buzzers are annoying anyway.

Wrong wiring to the new circuit board.

My 2010 tacoma doesn't have a buzzer. The lights automatically go off when you turn off the engine and open a door.

Most manufacturers demand the water pump be changed every 3 years.

If your thermostat sticks, you can over heat. You would also need to ignore or have a failed temp buzzer. Also at extreme temps, your temp sensor can burn up. SO if you heard the buzzer, and then it quit- that did not mean you were out of the woods.

If you could still run on your scalded pistons, I would think a light bore job with new pistons would fix it.

check teh oil light pressure switch on the engine they often have a rubber boot over the wiring connections ,these boots tends to fill with oil throwing the oil light switch on ,must be a american market one because i have never seen this buzzer on the europeon ones

Have you checked that the headlight switch is in the right position? Are the headlights or parking lights still on when the key is removed?

If so, then rotate the lamp switch to the correct position and the buzzer will go off. Headlights and parking lights are not controlled through the key circuits.

is there any type of check engine light on or any type of warning light is the sound of the bell the same bell sound when you open your door or seatbelt warning
