This is an old thread but one of the top hits so I thought I'd share what was going on with my MAP sensor.

I started getting a CEL on cold starts about once every three months with a code P0106. I'd clear it myself and it would stay off while I was driving the car. I didn't notice any issues with acceleration or idle. Then it would come on once a month, then once a week, then daily, then on every start.

My local shop said it was ECU program related and I needed to have Nissan do a software update. I'm tuned with EcuTek so that wasn't something I was willing to do. My EcuTek tuner said it's more likely a circuit issue and recommended a different shop. That shop found the barometric pressure sensor wires had frayed and was probably causing a short on cold start. They replaced the wiring, and I've not had a CEL since.
