Hi All, '97 LX450 w/403k miles and no maintenance history before 370k mi. It's been a great vehicle so far.
I'm getting a:
P0401 exhaust gas recirculation flow insufficient detected error, followed by a
P0130 Bank 1 Sensor 1 error (details attached)
Question - What are the chances that the EGR is causing the Bank 1 Sensor 1 alerts? Alternatively what are the chances that the Bank 1 Sensor 1 alerts are causing the EGR errors? I'll buy both Denso O2 sensors and a new EGR, but obviously I'd like to spend as little as possible and not have to return things.
Thanks much for any thoughts.
