Yep, part of the MAS.From what I read about the high voltage error I have to buy a $130 unit and hook it to a PC. All that because coolant is low (they say the error is nothing else and that refilling coolent doesnt make it go away, from the big thread about it).
The temp sensor would be an easy fix if I knew where the thing was. Unless it's actually the Mass Air Flow sensor?
The OP is showing code P0114, which is for an intermittent intake air temperature circuit.If you are referring to the ambient air temp sensor, it is plugged into the plastic frame on the right (passenger side) of the front bumper's air intake area. You can get to it by removing the right (passenger side) wheel well liner and removing some plastic splash guards and most of the front air dam.
I (and others) replace the sensor for the winter with one that has a resistor across the two terminal pins to artificially trick the Volt into thinking it's warmer outside than it is. Why? It prevents ERDTT (Engine Running Do To Temperature) on short trips that don't require an engine assist to heat the cabin. Otherwise my engine will run when the outside temps are at or below 25°F regardless of how much battery I have.
Just so you know, that isn’t true.So nobody knows the answer to this? These sensors can fail in two ways: 1. Wiring 2. Sensor. If its wiring then it reports the air being very cold. If its the sensor it reports the air being really hot. My car is reporting it really hot.
Where is this sensor???? Please dont tell me I have to take my intake apart because its underneath it...
That's usually true for other cars I have worked on but it seems your right the Volt may be different.Just so you know, that isn’t true.
I didn't realize 100,000 was high miles. My car is currently at 110,000 and I would like to get at least 200-250,000 miles out of it. I have to say, I haven't heard anyone consider 100k high miles since the 1980s.My car is high mileage now so anything out of the ordinary could cause problems. .
