Oil Pressure Sender - 1995 Pajero

Post by WeeMagna » 15 Dec 2016, 09:11

Hi everyone.

I hope someone might be able to help.

I need to change the oil pressure sender unit - 1995 Pajero GLX 3.5 quad cam (double cam each side) 6G74. Build date 11/95 but the paint trim plate says 9/95.

The problem I have is the sender unit is not connected. The original sender unit is installed but the wire is not connected. However the meter is working !! This tells me there must be a connected sender unit...somewhere, otherwise the meter would not be working at all. The fault is the meter works some times but 2 out of 3 times it does not work, which tells me the sender unit is faulty.

My question is, where could a replacement unit be mounted to the engine (other than the original location) ? I have read that people do some times install a replacement unit leaving the original in place. But I cannot find where on the engine.

Thanks in advance :)

Hello mate,

The DOHC 6g74 from 1995 is much like the DOHC 6g72 from around that same year.

If i recall correctly there are two parts for oil pressure.

There is a oil pressure switch unit and a oil pressure gauge unit.

Sounds to me that the gauge unit is working but perhaps the wiring to is is dodgy
Not sure if in your case the switch is disconnected but the wiring loom for this is normally wrapped together for both wires for the gauge and the switch units.

The link below talks about it and the picture below is from that website as the switch and gauge are next to each other.

The only place this could otherwise be relocated to is from a tap off an aftermarket adaptor plate at the oil filter.
Although not very common imo for it to be relocated.

Thanks mate..

That is very helpful. I didn't realise there were 2 sensors involved. I can only see one, which has a wire but is not connected. Maybe the other one is above the oil filter out of sight. I might put it up on the ramps to get a better look.

Thanks again.

Cheers
