I have a p1258 and po 102 code

Question

Do I need to replace my ETC Sensor?

Answer 1

HI there,

The code indicates an issue with the engine coolant. This could be a ECT failure, however if the truck is overheating then you would get the same code. The other code is for the mass air flow sensor. If the truck is not overheating or if the fans are not on constantly, then you should change the ect.
