Check Engine Code P0030,P0032

[Chapvrx]

hello can some one help with identifying what could be the issue , Check Engine, Port engine code :

(p0030 ECM Heater Power Stage Fault for Lambda sensor upstream of catalyst),

(p0032 ECM Heater Power Stage fault for lambda sensor upstream of catalyst-short circuit to V+)

Picked my boat up from winterization, on my first run and right away got this warning, otherwise boat runs normal. Thank You in advance for the support

These codes are identifying issues with the oxygen sensors. These are narrow band sensors that report if you are richer or leaner than stoich to the ecu. They use built in heaters to get up to temp, and only them, will they be considered “accurate”. It sounds like an issue with the heaters.

The good news is that these are narrow band, so they will not affect any fueling with any kind of load on the engine, so your boat should continue to run fine.

Pre Cat is either shorted to a 12v source of the sensor itself is bad

I apologize for the delay on this, but yes, you could absolutely replace the sensors yourself.
