trouble codes. Please help.
1. Bank 2 is lean.
I understand that this is likely either a faulty o2 sensor or a faulty spark plug. Is this right? I am leaning more to the o2 sensor. Also bank 2 is the passanger side right?
2. TTC Pressure control solenoid CKT open.
This is how in came out on the diagnostic tool. I honestly do not know what it means. Can anyone interpret this for me.
Much thanks in advance!
