NM35 Intake Temp sensor

I have an informeter plugged in to my OBDII, showing intake temp etc.

Where is the sensor that monitors this ? AFM or TB

I have very high temps when cars been sitting aound and takes ages to cool down whilst driving.

Was at 70deg last hot day .

cheers

Thats in the air filter section not throttle body

hmm maybe sucking in hot engine bay air through open duct, don't have power duct seals.

didn't think it really mattered once car is in motion..

Not sure where your intake air temperature sensor is but it's common to see upwards of 70 degrees as it's just a slow reading sensor which reads the temperature of the housing it's sitting in and it's connected to the cylinder head via the intake plenum on an RB so it just measures heat soak basically.

It's normal for me to be on the side of the road and see 69 and 70 once you get it in 3rd or 4th and apply some boost you can quickly see upwards of 10 degrees drop almost by the end of a pull getting cool air flow through it is the key sitting stationery always cooks your iat sensors.

Yeah sounds right as no fresh air is moving through it stationary. The intake temps will be 10-15deg hotter than ambient with radiant heat

So, would falsely read higher temps affect tune and power output via the stock ecu?

[mr skidz]

If it's high enough to trigger enrichment/retard yes

IAT sensor is in the AFM.
