This sounds like it can be one of two problems, either you have a connection/wiring issue or the ECM is bad and needs to be replaced. The PCM will need to be programmed by a shop.

Here is a guide so you can double check the wiring.

There looks like there is 2 sensors did you replace them both?

Please let us know what happens.
