Code Tech Notes

On certain models, this code can falsely set during a low battery condition. This can also trigger certain HO2S heater sensor codes. If only these codes are set and the vehicle is not exhibiting low battery symptoms, clear the DTCs and perform a couple of engine starts allowing the engine to run for a minute, then shut down and allow the ECM to power down, about a minute. Restart the engine. If no DTCs reset, no further action is necessary. If the DTCs reset, check the ECM power and Ground circuits, as low voltage to the ECM can cause these DTCs to set.

Check the Engine Control Module (ECM) fuse, if the fuse is OK, try erasing the code first and if the code comes back you may have to reprogram or replace the ECM.
