It could possibly be a faulty gauge, this is a pretty common issue for Trailblazers. Here's a link with more information about these GM gauge problems. Also, where you can purchase replacement parts on Amazon if you want to do the repair yourself.

Most likely the oil pressure sending unit is going bad or has a loose connection,but it would be safe to have a manual oil pressure test done to be sure it's not a problem with the oil pump.

2005 FLSTCI-Oil sensor is illuminating at idle. Goes away above idle.


Don't worry about it Bro, put a lower pressure sensor on it. I've had guys crying to me that put a oil pressure gage on there Shovelhead, good pressure when first start up, after warm the gage goes to zero. Brutha, Hawg pumps ain't made to build pressure, just circulate oil is all they do. Your oil is circulating thru the engine now. Like I said, if your that concerned about it, replace the sensor.Safe trip Bro.

If my fuel gage on my 2005 Chevy Aveo doesn't work, how do you fix it? This started @ 78,000 miles


If your mileage has dropped to half, I would be worried about what is wrong with the car. Chances are it is running very rich and using way more fuel than it should.

Remove the oil pressure sending unit and have a test gauge hooked up and see if the sending unit is defective. If you really have low pressure the engine should be making lots of noises.

Chevy cavalier 2005 87000 miles remote flakey, odometer won't display milage but will display trip data?


Hello William,

The key fobs are wearing out and need to be replaced. Sometimes taking them apart and cleaning the switch contacts and battery contacts will extend their lives but they are not built to last.

I believe your vehicles ECU sends the mileage data to the instrument panel cluster...in which the LCD odometer display has failed.

The oil pressure gage is reading zero and the oil is full. How can I tell if it is the gage or the oil pump?


It is quite possible that the Oil pressure guage is faulty or else with a zero reading of the oil pressure the engine would have packed out. So removing the valve door will confirm if there is oil flow and confirm the guage. You can also remove the line to the guage and connect the line to a bottle, when the engine starts up the oil pressure will be displayed with a good pressure spray.... but be careful not be spray it all over with a loose joint.

I have a 2005 Chevy Equinox but no owners manual. There is a light on the dashboard that comes on that show a picture of a car with what looks like a tool in the center. Can anyone tell me what this...


I believe that would be your "maintenance due" light. Most GM vehicles as of 2005 or so have a program built in to the vehicles computer that will let you know when it is time for your normal service to be performed. It measures this by how many times the vehicle is started, how long it is run for, etc. Sometimes it will come on after 3000 miles, sometimes 5000 miles and sometimes more. GM says that once the light comes on, they recommend you have an oil and filter change and any other necessary work done within 500 miles of the light illuminating. On average the light will come on about every 5000 miles but it can go to 8000 miles. I would suggest no matter what that the oil and filter be changed every 8000 miles at most with regular and not synthetic oil. You can always do the service sooner than that. Transaxles should be serviced at 30,000 miles or less on front and all wheel drive models on the Equinox. Please rate me on this answer.
