Hi All,
I'm flummoxed by my little Yaris, even after reading others with P0487 problems.
I had the P0487. I unplugged the EGR loom, checked it, cleaned the contacts, looked over the solenoid, reconnected it and cleared the code. A few days later, it came back so I put in a brand new EGR with solenoid and cleared the code.
A few days later it came back shortly after starting the car. After driving for ~30min I could clear it and it would stay clear until the next morning. Repea
