Where is the ambient temp sensor located on a 2001 S40 Volvo?

    I've looked under the hood on the drivers side behind the headlight and couldn't locate the part. So I should look under the front bumper on the drivers side?

    I assume this is the problem, the dealer said it was? The gage on the dash that tells what the outside temp is was reading 140F the other day when it was 40F outside. Now it just has a ----------- where the reading was?

    Thanks in advance

Look around the front bumper near the little grille area.. That would be 16" above the ground and away from the engine so the readings would be better.

Ambient temperature
Indicates the temperature of the outside air (only accurate while driving) approx. 16 inches (40 cm) above road surface. The warning function comes on if the ambient temperature is between 23°F to 36°F (-5°C and + 2°C) to warn you that there might be ice on the road. The temperature and the frost symbol will be shown in the display.

The sunlight sensor (located at the top of the dashboard in the speaker frame at the passenger side) should not be covered in any way as this could cause incorrect information to be sent to the ECC(electronic climate control) system.

2001 Volvo s40 seems to stall and not start for ten to 15 min. Also has high temperature reading that is false as car is not really hot.

You need to look at the temp sending unit it's probably faulty anthor issue with volvo is dirty throttle body's this raises havoc on the car they idle up down all over the map also you should change the thermostat too as a precautionary measure make sure it's the right temp for your year of your car thanx Chris

You don't! This is all computer controlled and dependant on a variety of sensors. Let me know if you need anything else.

Replaced thermostat for 2001 Volvo S40, however, car is still reading as if it were hot. Coolant also added. What could be further issue? A sensor is what the repair garage suggested. Has anyone else had...

I recently took my car in for this problem. The thermostat was replaced a year ago. This time they replaced the thermostat and the IAT (air intake temperature sensor). The thermostat was 20 and the IAT was 50, with labor it all came to $140. Most sites online that I found suggested replacing both the sensor and the thermostat at the same time. When the thermostat goes, it usually takes the sensor with it. So I'd have them replace your sensor too. Good luck.
