Question about 1997 Ford F150 Regular Cab

1 Answer

High oil pressure

05 Avalanche, 5.3 liter, 85K miles. I have an orange engine symbol in the dash and when I take off from an itersection or just rev the engine in the driveway, as the rpm go up so does the oil pressure. at about 2500-3000 rpm the oil pressure will go up to about 60-70 lbs. The pressure usuall sat about 40 lbs. What's wrong?

This is a normal occurrence. The oil pressure is directly correlated to engine RPM. your check engine light is related to something else.

If my 2004 chevy silverado oil pressure gage stays at 80 psi could this hurt the engine


I would want to know what the actual oil pressure is. The sending unit or the gauge on the dash could have failed.
There is a pressure relief valve to prevent oil pressure from going too high, but staying at 80psi would not be good for a long time.

5.0 liter 91 ford f150 xlt lariat engine is idling at 2000 rpm, how do i rev down and how hsrd is it to change the oil pump


ther biggest cause for this problem after making sure all throttle cables and cruise cables,and if equipt. kick down cables are sticking...is a leaking intake gasket usually the one between the upper and lower intake...check all vaccuum lines for leakes and the brake booster...as for the oil pump if its 4x4 it is quite the chore...5.0lt are famous for low oil pressure if they are high mileage from bearing wear..if your not experienced in big jobs take it to a pro...if you are going by your dash gauge put a mechanical gayge on it to verify the pressure...maybe its just a sender!

I have a 2007 chevrolet avalanche LT and everytime im driving it after a couple kms it will say low oil pressure turn off engine????


Hello: What weight oil is in the engine? How many miles since last oil change? How many miles on truck? The first thing you could do is replace the oil pressure sensor. You will have to remove the intake manifold to gain access to the oil pressure sensor. If the engine is not knocking or there isn't any valve train noise then it could be the oil pressure sensor when this message is displayed.

Oil preser lowers at lights


Hi there,

That is natural. The oil pressure rises in response to engine rpm's.

Idling at a light? Low oil pressure

55 mph on the highway? Higher oil pressure

Good job keeping an eye on it. And remember to change your oil every 3,000 miles.

Best regards

The engine seems to have oil, but the light is on in my 1995 nissan altima


The oil light means you have low oil pressure but not necessarily low oil.
Low oil pressure can lead to serious engine problems and should be fixed right away.

Wrench light is on and odometer shows negative mileage


The negative number means the car should have had it's oil changed that many miles ago. Oil life starts at 100% for new oil & counts down every 10%. At 15% the display will always show, which means it's near time to change the oil.

usersteve83, your oil may have been changed but the timer not reset. Reset the timer as shown...
1. Turn ignition to the "ON" position. (do not start engine)
2. Press SEL/RESET repeatedly until the oil life indicator is displayed.
3. Press & hold the SEL/RESET for about 10 seconds until it blinks then let go of the button.
4. Press the SEL/RESET again for about 5 seconds or until the oil life indicator resets to 100%.

Wrench = Maintenance Minder: Symbol letter & number...
Symbol A - Relace engine oil.
Symbol B - Replace engine oil & filter, Inspect front & rear brakes, Check parking brake adjustment, Visually inpest the tie rods, suspension components,driveshaft boots, brake hoses & line (including ABS), all fluid levels & their conditions, exhaust system, fuel lines & connections.
Symbol 1 - Rotate tires.
Symbol 2 - Replace air cleaner element (dusty conditions every 15K miles) & replace dust & pollen filter (behind glovebox) every 15K miles if mainly dusty or city driving.
Symbol 3 - Replace transmission fluid.
Symbol 4 - Replace spark plugs.
Symbol 5 - Replace engine coolant.

All above are taken from the 2006 Civic EX owner's manual.
