Hi,
The computer had been working fine except for needing periodic button cleaning. Recently the computed fuel economy has been off. The distance traveled is fine but the average consumed fuel off. It is using between 12 and 18% more fuel than is indicated.
Since my fuel gauge is not functional I got caught short and ran out of gas a couple of times before I realized that the computer is not accurate.
I ran the self test. The fuel consumption rate increased with engine RPM.
How does the computer actually determine the fuel consumption? Does it measure the open time on fuel injectors?
Any ideas?
