![]() Hi all, newbie from New Zealand here, I run a 2008 CX8090 and just love it, it works really well in our damp conditions especially grass seed. The last three years I've been randomly getting a Feeder Position Sensor error code coming up, it may be fine for 20 or 30hrs and then go crazy with the code re-occurring every few minutes and then stop after a hour or two just as randomly. When I bring up the fault archive it says, valid above normal. If I go to the voltage graph the voltages tracks within there correct range. As soon as I go out of faults it can return to repeated codes. We have replaced the sensor (twice now), last year the whole ECU with fresh info downloaded into it, inspected all the relevant wiring loom and plugs with no change in this behaviour. Just love my old CX but I am starting to run out of patience, can't seem to get any answers over here, any ideas? |

Does the new sensor fix it for a time?

I have no personal experience with it, but I would start with grounds. Assuming it is a 3 wire sensor I would also check resistance on the harness. I have some other trouble shooting ideas, but hopefully someone here has personal experience with it and go from there.

Hi, no new sensors have made no difference.

When I had an intermittent error, (thresher clutch overheated) it turned out to be a bad pin that had pushed out of connector a little bit. You could try running a jumper wire from the sensor into the back of the ccm plug to eliminate the possibility

Evoman, get yourself a buzzer or a light bulb and make a circuit to power them out of the harness connecting the sensor to the ecm. Buzzer works best for this and then wiggle the crap out of that harness to see if there are any internal breaks. A multimeter is the best if you have a helping hand though.
