I have a 95 eg coupe with a jdm gsr swap the main problem i am having right now is vtec is not hiting and it only reves out to 7k.. I have a speed sensor code also 17. I have tried 3 diffrent speed sensors that work and none of them had made a diffrence i have also tried changing the cluster now i am going to move on to trying a new engine harness. I have already wired up the knock sensor, v tec pressure switch and selonoide to the ecu if anyone can give me some good advice with this problem let me no

 

Take a look at the VSS plug and see if its corroded inside.
