Hi all, long-time lurker, first-time poster.
I'm persistently getting a P0071 error code, indicating a fault with the ambient temperature from the instrument cluster. From what I've found, the US car has an ambient temperature sensor in the front grill for the auto AC and OBC. My car lacks AC or OBC, and I can't locate the sensor. Will it still have one? I removed the front bumper to search for it and found a blanking grommet where I believe it should be. When using an OBD scanner, I discovered that the ambient temperature according to the DME is 87°F, which seemed to be read from the MAF sensor, as the values changed when this was removed and would have been roughly correct. However, the temperature from the instrument cluster displayed -40°F. Does the instrument cluster take this data from the MAF sensor as well, indicating a wiring issue? Or is there a separate sensor in a different place on European cars?
Thanks.
