Ambient temp display is low
On my 93 400E the ambient temperature display appears OK but the actual temp displays a reading about 18-20 degrees F. too low. What would cause this to happen and what is the best way to resolve this issue?
Thank you... Tobias MB 4 MBs |

Check resistance value of the sensor, plugs in under the fuse box.
At 68F the sensor should read 3750+-50ohms At 32F the sensor should read 9800+-100 ohms.
