P0125 Engine Management Light

[SR71 Blackbird]

Hi,

Got this error a month ago. Ive changed the thermostat, coolant sensor and put new coolant. Also I have reset the engine management system. But the engine management light keeps coming back on.

Have you made sure there is no air-lock in the system. You are not losing any coolant?

[SR71 Blackbird]

Theres no coolant leaking and Ive bleed the system and the reserve tank is full

EXTRA INFORMATION

The last thing that I changed was the coolant sensor and I reset the engine management but still come on when I drove less than a mile. But after I drove the car for a good 20 miles it turned off but after a few days it came back and hasn't turned off since.

What tool do you use to read the code? Have you tried a genuine Toyota tester?

No Ive used that torque app to check it
