yesterday I took a vss to a friends house to test it in his 98 civic to see if it was was working because I couldnt get it to work in my car with my sir cluster. I took his out, then tested mine and it didnt work but thats not my problem.

When I went put his back in I put it in correctly plugged up the connector and reset the ecu. But for some reason his car is not getting a signal and is flashing a a check engine light. Anyone that might have any clue how to fix it let me know

The fuse is still good, the sensor is getting power and has a good ground. everything worked fine before but now it just wont work.

thanks in advance

 

I dunno, but I'll bump for ya'!

 

Stupid question for you:

How do you know the sensor is not sending a signal?

Do you know what code you are pulling (CEL)?

i know its not sending the signal b/c im getting no movement on the speedo and a CEL for vss... anyone got any ideas at all?

 

recently do a motor swap?

 

yeah my friend did a b20vtec swap about 5 months ago... everything has worked fine until i tried to test my vss in his car. when i put his back in it all the sudden doesnt work.

 

AHHH i finally figured it out, the positive pin on the vss connector was severely corroded, i cleaned it out b4 and it didnt work... but i tested the vss in a different car and it worked..

now after i decided to solder in a new 3P connector it works like a charm.

 

Perfect example of what to do when you get a CEL code and tackle a diagnosis procedure on your car. Always look at connections, pins, wires first... Usually that is the problem... Much cheaper....
