Hi there. If the same code is returning, check to see if the new pig tail is installed correctly. If the wires aren't in the right position, you will have the concern you're experiencing as it could be shorting the 5 volt reference signal. Use an electrical wiring diagram to verify proper wire orientation and correct as necessary. I strongly suggest acquiring a qualified technician to perform an inspection to avoid replacing unnecessary parts. YourMechanic has several technicians available that can assist you with a Check Engine Light is on inspection.
