How often do reference sensors really fail

[dr.occa]

What is the DME? I'm not familiar with that abbreviation.

All things grow old. It's one of the laws of thermodynamics. It's called entropy.

Sensors, fuses eventually need to be replaced. You may have questionable issues with your fuse block(s) in general.

dme is the ecu.

sensors will fail over time.

what version of fuel system is it? jetronic, k-jetronic.

also this forum is mostly toyota specific. besides a couple honda guys. you will find more help on the euro forums.
