Egr temperature sensor plug on motor

[Edjahman]

So I'm trying to replace the egr temperature sensor and I have no idea how to get the damn plug apart. I was looking at the other sensors and it looks like the have similar plugs with a flat square plastic piece on top and a tab that appears to need pressing down to unplug it but I'm not having much luck.

Any help would be appreciated

That looks like a barometric pressure sensor.

Those connectors have a lock that goes horizontal.

Yeah I was just using that plug as an example. I don't know how to open it.

It looks like the egr temperature and the egr differential and exhaust pressure sensors all have the same electrical plugs,

I already damaged the egr temperature electrical plug trying to get it apart and I was still unsuccessful unplugging it.

How do you open these electrical plugs?

Thank you

I used a hook on that ")" shape part and pried the hook towards the "aeA" and it should pop right off, then you got the red tab that has to slide out to the right looking at the push down lock from that angle.

Unfortunately I'm having zero luck with these type plugs. I'm pretty sure I've damaged at least a couple trying to get them open. They really are a pain.

maybe this video helps. Different sensor, but likely the same type of delphi plug.

OK thank you. I'll give it another go tomorrow.

Appreciate the responses!

Just some related FYI:

For the CM871 engines ...
If your trying to remove the EGR temp sensor plug off a CM871, the older style sensor and plug are glued together and not meant to come apart. This older style will also have a thick layer of heat-shrink wrap over the whole plug to indicate that it is not supposed to come apart. - If someone has this type of shrink-wrapped sensor/plug, they follow the wire back up the harness, then buried back about 1 foot or so back from the plug is another in-line plug. That plug is where it is intended to be removed from and not by cutting away the heat shrink at the sensor itself.
