Fault codes


Recommended Posts

A quick way to troubleshoot the issue is to swap the rear most post catalyst O2 sensors on the port and starboard exhaust pipes.  If you continue to get the SPN 3256 FMI 5 code then there is a connector, wiring, or ECM issue.  If it changes to a SPN 3266 FMI 5 code then the O2 sensor is probably faullty.
