hi steve my name its daniel

this code unfortunately points to an internal fault in the ECU/DME

I would suggest unhooking the vehicle battery for an hour to reboot the ECU, but if continues, you may need a new DME.

If you need more help please use the reply tab to continue our conversation. If no further assistance is needed, please consider rating me as 5 STAR!! It is much appreciated. You can rate at any time and we can continue to work on your question after you rate if needed - rating will not close out your question. Please do not forget to leave a positive rating as this is the only way I receive credit for my time and answer, thank you.
