OIL PRESSURE GAUGE PROBLEM
2006 Nissan Frontier • 88,000 miles
Thank you in advance if you can solve this problem.I have a 2006 Nissan Frontier and when Im sitting a a red light my oil pressure gauge go to almost 0 and when I press the gas it goes to what appears to be normal. Autoway Nissan nor Autoway Toyota can figure out why. They say there is no debris in oil pan screen or any loose debris in the timeing chain housing blocking oil flow and all oil pumps, gauges and sensors are working properly. This problem is also referenced on youtube with no resolve. Thanks Robert at MeNHer77@aol. Com by the way Im told by a large dealership witha full staff of techs that this for some reason cant be fixed ( what reason)?

Have they check the oil pressure sending unit for out of calibration and Also is the engine knocking?
Truck runs great nothing sounds abnormal great acceleration that gauge would bother anyone by apperance
This can be several thing that cancause this. The easiest thing to do is replace the oil filter first. Oil filters can cuse this alot of times. I only reccomned napa, wix, purolator, or bosch filters. Then if it still does it get amanual gauge and see what it does, if it does the same thing then it may be an internal problem like bearings not fitted tight enough or worn parts.
Did they check and test the oil pressure sending unit or hook up a mechanical gauge to verify the actual oil pressure?
They even tried a 2 stage oil filter. As far as worn parts or bearings thanks for playing you tried.
Yes that was the first thing they tried b-4 the dropping the oil pan and inspecting the timing chain compartment for loose debris blocking the oil passages
Cant remember what he said as far as numbers on that. Just feel like im in a pickel on this truck purchase. Love the truck it runs fine. And Im really bothered that 2 dealerships cant figure this out. They even claim they brought in a Nissan Field Engineer and tech to advise. I know it just a gauge but it is an important one.
Well the pump would need to be pulled off and checked for clearances first andit could be a pressure valve problem with it sticking or somethingsimlar like that. You could try running 10w30 oilinsted oaf 5 w30 if you are running that currently. But if it goes to normal when revving I wouldn't worry abot it to much
I traded in a 2004 GMC Envoy with only 57k to get this 2006 Nissan Frontier Crew Cab with 88k mile thinking this moter is good for atleast 300K mile if pampered and low use. They are getting ready to offer me a 1 year warranty on the motor. Because they cant figure out how to fix this problem. Im thinking about asking for 2 or 3 years.
Replaced heads on 4.7 and found lots of sludge on heads. Once completed and truck runs good but after it heats up the oil pressure drops off to 0. What could be the problem?
