I have a 07 dodge ram 1500 5.7l hemi 4x4 four door with 140, 000 miles...first issue is it seems almost everytime I step on the gas one single chime noise comes on no code for it did it once in awhile before now does non stop...what could it beee I have no idea.other problem is just got a code saying low oil pressure second time in last couple weeks I cleared it last timebut came on again.oil level is good oil pressure gauge is reading right little under half way mark when idling and kicks rightup to 3/4 when u step on gas so seems to have good pressure what could be causing it I don't think the two things have anything to do with each other cause they didn't start at same time plus the single chime everytime I step on throttle been doing this for last week non stop and last time oil low pressure light came on was like 2weeks ago.please help thanks

 

Bad oil pressure sending unit. Check with a direct reading gauge that oil pressure is good. When the single chime happens see if you can catch a light coming on.

 

How can I check oil pressure directly? And no light comes on at all for the single chime its weird

 

Could be a related issue. It's your call, you can double check with a gauge. However the oil pressure sending unit is a common fail item. They are a cheap replacement.

 

Do you have access to a scan tool that can read the pids? Then you'll know for sure if your sensor is AFU.

 

Ill go check my scan tool now to see if it does.How bad is it to change the sending unit.pretty simple? Thanks

 

Yes it reads pids what do I look for after I search pids?

 

I know is sounds weird. Check for a videos on u tube. There may even be one on here. You can do a search. Yes pretty simple to change.
