I assume this car has a warning light. You should have a mechanic remove the oil pressure sender unit and replace it with a gauge. This will show what is really going on. I suspect the sender is faulty.

Raymond, to fix the P0106, clean your throttle body with the battery disconnected. Very common problem with our trucks. Not related to the oil sending unit.

    P0106 is for the MAP sensor not the throttle body. For oil pressure problem, could be oil pressure switch or a bad stepper motor that drives the gauge.

I have a 04 gmc envoy xuv unknown driver message no security light will not start battery was bad got new one tryed passlock reset stills say unknown driver no start


It's a short in the instrument cluster.
I had the same problem with my 2004 XUV.
It started in early December of 2007.
Intermittent manifestations, than more persistent.
Took it to the GMC Dealer --
Of course, the Truck wouldn't do it's tricks for the Tech.
They replaced the ignition switch and sent me home.
It got progressively worse.
I waited until I was sure it would do it for the tech.
Took it back in to GMC Dealer--
It's a short in the instrument cluster.
They needed to replace the entire cluster.
I bought an extended warranty when I bought the truck.
The warranty is still in effect --
So I only had to pay the $100 deductible.
No Idea what it might cost otherwise.

My 2004 GMC Envoy XUV was squeeling then I felt the pressure in the steering wheel and now turning the wheel is like a power workout at the gym. Can I change the power steering myself?


Sounds like the power steering pump has seized up. The question of whether you can change it yourself depends on your abilities and knowledge of auto mechanics, and having the necessary tools.

Oil pressure gauge is zeroed out (0); oil is fine; engine started to knock (valve knocking). Help!! Engine was never low on oil.


Oil was check with a dipstick?then you only check its volume,here the real check you lost pressure.The oil pump supplies oil to valves to timing chain but is not the device that creates pressure, pressure is created by the cranksahft and its main bearing, if the oil pump fails then the crankshaft cannot create the needed pressure ,is the pan hit? Do not turn this on no more, youll need to get it inspected, if you run ir it will just freeze up. tow it to a repair area,

i would say it's long overdue. i would think the manufacturer would recomend changing the trans fluid at 25,000-30,000 miles. the owners manual will have regularly scheduled maintenance routines listed.

2004 GMC Envoy XUV mid-gate window won't roll up


be sure the gate is fully closed or it will not roll up if it is firmly in place and still does not go up you will have to remove the cover and see if the actuator plastic has broken off from the switch, it also could be a bent rod and or the switch is bad. Check fuses as well just to be sure before going to all the other work to pull cover off. Hope this is helpful and thanks for using Fix-ya.

My oil pressure gage just drops to 0!!!


You need to replace the oil pressure sending unit, this is what tells your gauge what the pressure is. For future information if your oil pressure drops again and its a real failed oil pump within a few minutes you will internally damage the engine. I would get a new Oil Pressure Sending Unit. Let me know if you have any questions.... Thanks!
