Earlier you stated that you don't have a dash readout, now your saying you have the sensor? Where dd you get that info and/or what makes you think that you now have a sensor?

Google comes up with: Motorcraft DY-1137 Coolant Temperature Sensor. Some sites show it as a Ambient Temperature Sensor.

Looking at the electrical diagram for my '09, the sensor mounted at near/behind the grill is the same connector shown in a diagram for the HVAC Module-EMTC. It could be that they all have the sensor which is used by the HVAC. There could be a PID for it that they found to show the readout too. Interesting.......

I don't have a dash readout. I have a obd ultragauge which tells me the outside temperature.

I know that just trying to figure old how it's doing it.

From my knowledge(guessing), all newer models have the outside air temp sensor. It's a software thing whether or not it displays it. Many sensors are available on the obd port, so instead of paying Ford, i pay Ultragauge and get to see

Can it log 20 PIDs at different time intervals at one time, load into a PC, graph the output and export into MS XL? That what my old/obsolete scanner can do. A newer one will probably do more and better!

There's is another temperature sensor as part of the AC unit to make condensation doesn't freeze. There's another temperature sensor for the interior too.

Although the Canadian Escape for '09 had DRL enabled, the service manual didn't show it as a feature that could be enabled. I've never heard of any '09 owner having it enabled, not that there wasn't just never posted.

Why would one need DRL while in Park?


Yes, the sensor is located behind the grill. However, the ambient air sensor DOES indeed interface to the climate control module. The temperature information is passed on to the display via the medium speed module communications network. Any other device on the MS-CAN network (like a reader) could also access the temperature information. See here:

Manual controls:

Automatic controls:

This is why it's complicated to get the temperature sensor working on a vehicle that was not configured for it originally - at least 2 devices (the EMTC/DATC module and the FDIM) must be properly programmed, and the sensor must be present and working.

As an aside, the DRL thing was just an observation - there's absolutely no reason for them to be on in park. That's just how GM vehicles used to work.

I guess that you didn't read my post above where I looked at my manual and seen the same diagrams that you posted? Yes, I now agree with you.

I wonder if GM uses a reduced output while in DRL like Ford does?

BTW: Where are you getting the diagrams from?

I was going to post the same diagrams.

I spoke with a Ford electrical engineer when the other thread was being discussed, and he said that the EMTC and DATC modules are programmed at the factory. They can't be flashed in the field, and the programming is not related to the Smart Junction Box. He said that your best bet is to find a module from wrecked Escape with factory outside temperature.

The FDIM does not need to be programmed, since the signals controlling it are sent on the MSCAN "network".

That does explain how the UltraGuage reads the ambient temperature without having the right EMTC, etc. modules.
