  1. 1000-5
About a month ago I had to do a new wire harness from varmits, but prior to that the temperature never displayed on the cluster.

Now that I’ve had the new wire harness, its flashing 7 times shortly and running the fan. So then I installed the new ECT sensor. Same issue.

Reset the trouble codes with jumper wire, still running into the same issue.

Could this be a fault in the ECM?
