SPN 3222 FMI 4 error code

[gibson]

Hi all,

I have an error code on our 2017 Tige R20 (Indmar 360)

Everything runs normally.

The error code SPN 3222 FMI 4 (Heater Open / Ground short) shows up within 30 seconds of starting and then followed by error code 3217 FMI 5 (Open/Lazy).

Any ideas what’s happening?

Sounds like O2 sensors to me. But also check your voltage is good, have had similar with low voltage.

Thanks

Do you happen to know the O2 sensor part numbers?

I checked the voltage. It’s good.

Thanks.
