Technical IBS, compatibility and pin issues

[WitleyPanda]

Part of a flashing odometers.

So got a replacement IBS, vendor confirm compatibility. However the stud/pin is only 25mm to the groove whilst the OEM fitted is 32mm, so the mating part does not lock on! I could and probably will swap over the pin bracket from the original.

Second more critical issue. It is actually one of the connector pins that has failed, rather than the sensor it self. The broken pin is in the female connector. Not obvious how this comes apart? Any ideas? ( Well used to electrical connectors and how to dis-assemble, but this one has me beat.)

They’re called Econoseal connectors and used by most models of car now. They *can* be disassembled but aren’t really designed to be.

Take a look at this website (as an example: plenty of others out there) that might help you

Econoseal Waterproof Connector Pair - 2 Way

2-way Econoseal automotive waterproof connector. Suits 0.5-1.5mm² cable and supplied as a male/female housing pair with all seals & terminals.

Also this (although it describes a 36 pin plug the process is similar for smaller ones) https://www.emeraldm3d.com/media/ppw/36way_Pin_Removal.pdf

Grateful for the response. Familiar with these connector. On the IBS cable end there is a green housing end, so no white locking plate. Hence my concern that it not a standard econoseal? There are two small rectangular holes in this which I could try to use an extraction blade. However as in the photo the second one is mid the sockets rather than aligned, unless this releases the green cap. Hopefully you can understand my confusion. I will search through my array of connectors and salvaged looms and see if I can find a similar one to experiment on, else buy a econoseal pair, in the hope they are inter matching.

Do keep us advised of progress - was the sensor significantly cheaper than the specific FIAT part number which (when I priced it fairly recently) seemed incredibly expensive? Thanks

Expensive. In theory OEM part but made by different supplier, Bosch, rather than ? So the mechanical construction different. ( supplier checked details from V5 but issue with pin length as mentioned.) Will update…….

Not an econoseal, least not as standard. ( unless there is a mini/micro version?) Not just colour, construction, but the IBS pins are smaller. ( Crawled under rear of Discovery and looked at connectors on bumper lights. They are econoseal, but far bigger etc.)

Thanks. OEM is (on mine) Magneti Marelli and the last time I enquired it was north of 150GBP. As you say mechanical issues should be easily sorted. Mine was sorted a while ago by FIAT Workshop - they swapped it out from an Alfa Mito they were breaking.

Ok, so we took the connector into surgery. Insert an extraction blade, rectangular pin into the aperture on the edge of the green cap. This moves off sideways, not axially ! You can then access the locking tab for the terminal, which can then be withdrawn from the rear of the connector.
Removing the broken pin needed a suitable tool, paper clip, extraction pin, to expel it from the terminal. Connector can then be carefully reassembled. Remember to slide green cap from the side as there is insufficient compliance to feed axially. I used Vaseline to further seal/ protect the pins and terminals, to protect from corrosion.

OUTCOME : did proxi alignment, rest date/time. Blue and Me now appears to function, no flashing odometer. No stop/start unavailable message. Only downside, I had to swap the grooved pin bracket from the old sensor, which now makes it a higher in position and at the extreme limit of the slack in the negative cable.

Released it back to main driver to put some miles on it. The ECU still only reads millivolts rather than circa 14v. Check those cables, connections another day.
