Hey Graham,

I have had this P0125 code on my 2004 SC 430.

I have replaced the thermostat, ECT Sensor, Coolant itself, the O2 sensor and I also needed a new exhaust. So I had mine replaced in September with a SS unit.

I was told to change the thermostat first (its about £20 for a gates thermostat & quite easy to do yourself).

Hopefully someone can help you Graham (& me too)

Hey Thomas

Thank you for your reply, a garage has told be thermostat and ECT sensors, I see 0v on b1 s1 and a big positive fuel trim, but not sure if my scan tool is any good, is yours still broken after all the sensors have been changed?
