I have a 2000 dx and i swapped in a cluster with the tach from a 99 protege. Everything works, but the engine check light comes on. WTF? I had the code read and it was P0118 ( coolant temp high input). I replace the coolant temo senor with a new one, erased and reset ecu and still check light. I putback the old cluster and the light goes off, then put the new one and check light again. Please i need some help.

 

you have a pm.
