I just change the oil on my wife's Cherokee last night. I noticed after I was done the Oil Pressure Gauge is not moving. I usually check that each time. I ran the engine, checked for leaks and even drove it to the gas station and back. All seems fine. Is there a fuse / sensor that could have gone bad?

I asked my wife if she noticed this? I got the response "I never look at those gauges - only the gas gauge"

Any ideas for me to check?

Thanks in advance -

check to see if maybe you knocked the wire off of the sencer when you changed the oil filter. Might be reason??.
