Default No voltage at Impact sensor

Airbag light on. Code is titled "Lack of Communication with right front impact sensor". Replaced sensor. No joy. Checked for power at sensor. No power. Voltage for this sensor comes from module under console. Is it a big job to remove console?

Anyone ever had this problem before?

While removing the console is somewhat a chore, it's not too bad. Just remove both arm rests off the seats before you try to pull it out. That makes the job a LOT easier.

The center console came out while we did some air conditioner work on SOOO BIG a while ago. Although that photo series was dedicated to A/C work, maybe you can spot that plug assembly in these two photos showing the center floor in the back ground.

Could be wiring. I had a recurring problem with a throttle positioning sensor in a Dodge Neon. In the end, I ohmed out the wires between the TPS and PCM. One of the wires had very high resistance, it was broken somewhere in the wiring loom. I spliced in another wire, jumping the bad portion, and that fixed the problem.
