volkom Posted January 7, 2017 Share Posted January 7, 2017 Just repalced a rear sensor on my 2006 focus estate . Still have same issue . 3 second long beep then nothing. I have read that the control module has dtc codes.. They are around 50 quid to replace on eBay.. Dont want to spend that much. If there is a problem with the wiring loom. Its not the sensor. Tried it on another connector. 3 click and vibrate. One does not. Quote Link to comment Share on other sites More sharing options...
iantt Posted January 7, 2017 Share Posted January 7, 2017 quite often its the wiring that corrodes through somewhere in the harness. Quote Link to comment Share on other sites More sharing options...
iantt Posted January 7, 2017 Share Posted January 7, 2017 check the sensor connector if you have a multi meter.which of the 4 does not work? Quote Link to comment Share on other sites More sharing options...
volkom Posted January 7, 2017 Author Share Posted January 7, 2017 Im pressuming its a wire/ connector issue. The one I have bought to replace the one i thought had failed works on other connectors. Its the second one from left looking at rear of car. Although the wiring loom looks ok. Which is why im thinking that the module has failed.

volkom Posted January 19, 2017 Author Share Posted January 19, 2017 Swapped over a different module. No change. Wiring loom it is then. £ 37 down the drain. Quote Link to comment Share on other sites More sharing options...
iantt Posted January 19, 2017 Share Posted January 19, 2017 Like I said, wiring harness corroded . Quote Link to comment Share on other sites More sharing options...
volkom Posted January 19, 2017 Author Share Posted January 19, 2017 Corrosion will be around that connection/sensor ?? As the other 3 are working/ ticking . Quote Link to comment Share on other sites More sharing options...

The one I have bought to replace the one i thought had failed works on other connectors. I would replace the whole worn out Ford set with a low cost aftermarket one. It will be much cheaper than just a single Ford sensor, and I dread to think what a Ford Stealer would want for the wiring loom. Just not worth it!

iantt Posted January 19, 2017 Share Posted January 19, 2017 Could be corroded anywhere from the connector to sensor to the multi plug. Quite often it's at a random point in harness. You can figure it out quite easily with a multimeter. Best way is disconect harness from sensor and multi plug end . Then unclip from bumper area. Then you can test on a workbench or kitchen table in the warm and repair as necessary. Quote Link to comment Share on other sites More sharing options...
volkom Posted January 20, 2017 Author Share Posted January 20, 2017 I do not think i am able to take the whole loom out. Part of it goes through to battery etc. Its all meshed together. .can it be where the multi plug direct from sensor .where that is meshed into the rest of the loom ?? Surly the wires from main multi plug are not wired in seperatly. The other 3 work. So it must be on the spur to the dogdy connecter. If that makes sense Quote Link to comment Share on other sites More sharing options...
