On a 2007 Chevy Uplander, the oil pressure sending unit is typically located near the oil filter on the engine block. It can be found on the driver's side, towards the rear of the engine. To access it, you may need to remove some components for better visibility. Always consult the vehicle's service manual for specific details and safety precautions.
The capacity according to my 09 owners manual is 4.0 quarts or 3.8 liters for engine oil with a new filter.
Changing the intermediate shaft on a 2007 Chevy Uplander typically takes about 2 to 4 hours, depending on the mechanic's experience and the availability of tools. The process involves removing the necessary components to access the shaft, which can be time-consuming. It's advisable to consult a repair manual or a professional for specific guidance based on your situation.
To program a 2007 Chevy Uplander key fob, first, insert your key into the ignition and turn it to the "On" position without starting the engine. Then, press and hold the "Unlock" button on the driver’s door while pressing the "Lock" button on the key fob three times within 10 seconds. Release the "Unlock" button, and the vehicle should respond with a chime, indicating that the fob is programmed. Repeat the process for additional fobs if needed.
To reset your 2007 Chevy Uplander, start by disconnecting the negative battery cable for about 15 minutes to reset the vehicle's electronic systems. After reconnecting the cable, turn the ignition to the "On" position without starting the engine and allow it to remain for a few moments. This may help reset the warning lights and other electronic features. If you're looking to reset the oil change light, turn the ignition to "On," press the gas pedal three times within five seconds, and the light should reset.

I am willing to bet that you have had someting inside your gas tank or dash worked on recently. The issue is that the plug for your sending unit is on backwards or the wires to your gauge are reversed.
