I am wondering if your oil pressure sending unit is not working properly. I suggest you take it in and they will make sure nothing serious is going on. A few dollars spent on a check up might save you from buying another engine or car. Check your oil pump pressure as well.
I had the same problem in my Yukon Denali And after 4 throttle body's, replacing gas pedal, rewiring the grounds replacing sensors, took it to not one but two GMC dealerships who were useless they can't fix their own trucks they're not the brightest !!!! After thousands of dollars I found a mechanic very familiar with this issue you want the solution it will cost ya 500$ for me to tell ya!! Just kidding I know how frustrating this problem is okay here is the fix the problem is these electric throttle bodies are GARBAGE!!!!!!! Don't matter what u do or what u replace it will come back on unless u convert your electric throttle body to the old cable throttle the actual fix was 900$ but I spent thousands and thousands trying to fix it!!! Please save your money and tell ur mechanic u want to convert to the old cable throttle!!! Gmc is well aware of the problem but won't fix it for u cuz they're useless
The check engine light will not come on if there is a problem with fluids. The check engine light will illuminate if there is a fault with a senor, a computer controlled device, or a computer monitored system. There are literally thousands of possibilities that can turn on the check engine light.
The first thing that needs to be done is to scan the computer to see what codes are present. This will help narrow down the possibilities.
Some common problems are EGR codes and Evap codes.
I assume you mean the check engine light?If your fluids are all good and your car runs fine,it should not be a problem unless it is required to be out for state vehicle inspection.There are so many things which can turn it on that people literally have spent thousands replacing what a computer readout tells them and a $2 light is still working.For real,it seems to work when nothing is wrong,but not work when there are quite serious issues.You can call any mechanic and if they are legitimate,they should say basically the same.If they say bring it in and we'll look at it,never ever go there.If you have any questions or need more help,just comment here and I will get an autolink to your post and reply ASAP.Greg
Normally the Oil Light is indicating lack of Oil Pressure and/or Low Oil Level in the crankcase. You don't state if the Oil Level is in the safe driving range. Pull the Dipstick and check the Oil Level. If it is below the Add line, you are probably due to get the Oil changed so do so immediately. If the Oil Level is full, then you may well have a problem in the Oil Pressure Switch. Have it checked out by a Certified Mechanic before something serious happens to your engine. No Oil pressure can result in nearly instant disaster to the Connecting Rod and Main Bearings as well as the Crankshaft, Camshaft and Lifters.
I doesn't matter what engine is in your car. Lack of Oil Pressure can end up costing you literally thousands of dollars.
Unfortunately there are certain things that only the dealer can do with the tools that they have spent thousands of dollars on. They have them to help people in this particular situation. I use dealer information on a regular basis because sometimes problems can be very hard to repair when it comes to sensitive electronics. This is an option that you have to avoid more expensive outcomes. Hope this helps, good luck!
