im getting a steady check engine light going on , and when i run a fault code check , i get code 1234 , this is speedometer A signal ,

 what does this mean ,and how can i remedy it?

[johna]

If it is of any help... Bentley E36 manual says Speedometer "A" signal (DME 3.3.1 only): Check wiring between Instrument cluster and DME module.

Pin 73 of the DME is Vehicle speed signal and this goes to pin 10 of C2 on the instrument cluster.

i think this is just pointing to me needing a new cluster

Does your speedo work properly?

[jonboy318is]

the speedometer works, but the econometer doesnt.... it either is all the way to the 40+ MPG when im off the gas , or all the way to 0 MPG when im on the gas
