False flow readings from flow sensor.
 

How can I test my flow sensor for proper operation. I'm getting false flow readings on the gauge with the car idling only and with the gear in neutral. I assume vibrations from the engine is not the problem. I tried rotating the flow sensor in few different positions with no luck. I found this while google searching and will give it a try:

**********IMPORTANT********************

I spent a long time trying to figure out why my flow sensor kept picking up readings when i wasnt spraying! Very annoying! So go to autozone buy some heat wrap
and wrap the flow sensor *thats connected to the FAV* this will stop the false flow. Found out magnetic fields can cause this so save yourself some time....Your Welcome

Check the routing the yellow harness is not close to a noise line just as a ignition coil harness. Try routing it differently.

I'll try that suggestion, didn't even think harness itself might be the issue.

Thanks.

The controller is reading pulses from the sensor, it can tell the difference between noise or real signal.

Unclip the sensor from the flow tube and tell me if you see false readings. If it does, the noise is external to the sensor.

Getting reading readings with the sensor unclipped. Tried routing the sensor harness in few different ways without any luck. Still have few options before I give up and sell it.

unplug he sensor at the controller end and let me know.

will do thanks.

OK unplugged sensor and harness and no flow bars lighting up. Drove around for a good half hour. I'm going to try reroute the harness one more time and then I'm out of options. Funny thing is I had no problems for the first day after the install.

it appears the reroute is the next option

I ran the flow sensor harness away from everything's and wrapped it with some wire loom. So far no readings, but driving the very easy and making sure I don't spray any meth. Once I'm completely sure I have no false readings I will give it some gas and see if I fixed my issue.
