Nope, but I would definately fix it. Couldn't tell you what is wrong but theres not much It could be. You have the sending unit and the reciever gauge. Other than that. The only thing that could keep that gauge from working is a bad fuze or faulty wiring.

If you haven't already, save this. If you have, make sure to refer back to it alot. Good luck. You'll get it fixed.

check the wire on the sensor and ensure that it is still attached. It may be temporarially grounding out on something

oil pressure at idle is like 0.45, yours might be normal
