Question: i have a check gauges with oil pressure problem.
What make and year vehicle?
GMC Envoy 2002.
OK. The check gauges warning comes on because of the low oil pressure problem. Is the oil pressure always low, only at idle, high engine speeds or does it bounce around?
On high engine speed i have an idle oil pressure and warning light.
OK. A common problem is a bad oil pressure switch on the engine. To be sure, an oil pressure gauge would need to be installed on the engine to check the actual internal oil pressure of the engine. This would normally cause engine noises.
some told me it would be a problem with the sensor. is that right?
Yes, they are common to fail. It is called a switch or sensor- same part.
and where is the placement of this switch?
It is located just above the oil filter.
so i can remove it from below?
yes.
do u know how much it cost?
but why it works on high speed and just when i press the pedal even on park.
They jump around like that. Having a pressure gauge installed would be the perfect test. And how to make that?
A gauge is a tool that test the engine oil pressure.
i should buy it and test the pressure.
It would be cheaper to just replace the switch and see if it worked, or have a mechanic test the oil pressure with his gauge. The gauge is an expensive tool.
ohhh. u told me its about 30$.
i think here in leb it would be arround 90$.
The switch is about $30. A gauge to test the oil pressure can cost over $100 U.S.D.
Lebanon #100: im talking about the sensor.
Yes, the sensor is about $30.
here in Lebanon would b 90$
Yes.
