89 260e fault codes
 

I need the fault codes for troubleshooting the " check engine" light on my 1989 260e. I'm getting a code of eight flashes of the LED light . Any help would be appreciated, Tom

The code refers to a problem with the altitude correction sensor.

altitude sensor
 

I have been told that this part rarely fails by both the dealer and a MB indy shop here in Phoenix AZ so I picked up another alt sensor from a salvage yard last year. It was okay for awhile but as soon as the temp here in AZ got hot ; the "check engine" light came on again. Thank-you for your reply; I just wanted to verify the code since "eight flashes" is the code for a coolant sensor in some of the other models. Any other ideas? Tom
