Hello I am hoping that someone will be able to make suggestions of what should be the next course of action to resolve what appears to be an erroneous code P0031. I have replace with both oxy sensors (oe denso) bank one sensor one and bank one senor two and this did not resolve the problem with a P0031 code reappearing after having cleared the codes from the ECU... I have platinum BKR6EP plugs that have about 60,000 miles on them. The engine runs fine. My truck is a 2003 Tundra extended cab with 155,000 miles. V8 4.7 litre engine. I plan to locate the PCM (ecu) and check the connections next.
Any suggestions would be appreciated.
