Hello!
I have two error codes on my starboard V8-380-CE-D:
SPN: 3261 Exhaust 2 O2-1 HeaterFMI: 4 Voltage below normal or shorted low
SPN: 3271 Exhaust 2 O2-2 HeaterFMI: 4 Voltage below normal or shorted low
These are the only two codes being thrown. The engine maxes out at 4500 RPM at WOT under load. I think it may be limiting RPMs because of the O2 sensor errors.
Which exhaust is "Exhaust 2"? Is it the right or left side when looking at the front of the engine? I assume O2-1 is the front upstream O2 sensor and O2-2 is the rear downstream sensor. Is that correct?
Thanks!
