A 94 Acura Legend has [D4] flash, speedometer needle fluctiate, and code 4 was registered... I have checked the crank sensors and CYL sensors they each have 730 ohm (in spec), also checked wires and connectors from crank sensor to ECM, they seen OK, could not find any broken wire or loose connector. After clear memory and restart engine, the [check engine] and [D4] do not light up while car was not moving. The problem occur while driving, speedometer needle drop to zero and fluctuate, [D4] flash, and code 4 was registered... At first, I thuoght the speed sensor (VSS) problem but code 17 was never registered. Therefore I am not sure it was VSS problem.
Some one please help .... Thank you.
Well the same thing is happing with me and i have a 95 Legend i read in the book that when D4 flashes there is a transmission problem, but i don't know why my speedo is jumping. let me know if you find something and i will do the same...
