I’m monitoring my intake sensors, I have a slight rough ideal so thinking it could be MAP or MAF.

Looking at the PIDS to monitor there’s a lot of temps to monitor?

Wondering PIDs are getting there information from.

I’m only aware of three on the intake track. IAT at airbox, MAP which also monitors temp - on intake horn, and there an IAT on the intake manifold plate by the fuel rail.

My trucks been cold for a week and checking temps on the monitor they all show close to the same ambient air temp except the intake manifold temp which significantly higher than the rest.

Does this indicate an issue with the sensor and which sensor actually is it?

Not sure how there can be so many intake system PIDs for only a few sensors?
