sounds like maybe one of the 2 sensors you have there that you swapped is bad?.

Swapping sensors around should be done with caution as well. Many look the same style/color but may not be compatible. In the case of the EGR pressure sensor and the Exhaust gas pressure sensors,.. they may be the same part#'s on some enignes. Before assuming though, a person should always look on quickserv.com and ensure they have the right part#'s/are the same before swapping them around.
