I just changed the oil and filter on my LX420 twin cam how do I get the blinking light to go out. Its a 2006


  • The Service Monitor meter contains a service minder function that utilizes the 4-digit LCD display.
  • The letters "CHG" will display followed by the letters "OIL" and then followed by the meter accumulated time.
  • CHG"/"OIL"/TIME will alternate on the display for five (5) minutes after the meter reaches 50 hours.
  • While the LCD is displaying the "CHG"/"OIL"/TIME letters, the red LED "oil symbol" will also be flashing for the entire five (5) minutes.
The display will also flash as described above for five (5) minutes every time the tractor has been started during the maintenance time interval. The interval will occur every 50 hours and will be in effect for two (2) hours.( Example: this feature will display from 50-52 hrs., 100-102 hrs., 150-152 hrs etc...)
THE METER DISPLAY WILL RESET TO NORMAL AUTOMATICALLY, after the reminder maintenance time interval of two (2) hours. There is no method of manually re-setting this Service Monitor gauge.

Where is oil pressure switch on 1992 ford 150


Most oil pressure switches/sending units were located are near the oil filter. Did you have the same symptoms before you changed the oil pump? How many miles on your engine? As the bearings (main, rod, camshaft, etc) wear, the gap where oil flows through gets larger, and oil pressure will decrease. If a direct reading gauge shows very low oil pressure at idle, it's time to rebuild or replace the engine.

1990 f-350 w/351m. loose oil press after runs short time. r&r'd new oil pmp & p.u. screen ttl clean short time ago. wen press drops, lftrs clack. any ideas b4 I drop pan again. thnx 4 ur help --- Ed.


It sound like a bearing issue. I would recommend checking oil pressure. This should be done both cold and hot. Allow engine to cool over night, you can get an inexpensive oil pressure tester at most parts stores. Remove the oil pressure sender near the oil filter. Attach the oil pressure tester to this port. Start and run engine. Cold oil pressure should ideally be around 40psi, with hot oil pressure around 20. If the pressure drops significantly or never really is satisfactory this may indicate a larger issue. It could have a bad or restricted oil filter. It could also have excessive clearance on the bearings, indicating wear and the need for new bearings.

What should the cold start oil psi and the 190 degree warm up oil psi be on a 2000 to 2002 gmc Yukon with a 5.3 eng


Different engines can show different values. Sometimes it is the sensor itself that causes the variation. The pressures that you are witnessing are well within operation norms and are nothing to be worried about. As long as you don't experience severe drops in oil pressure during acceleration and deceleration, then the oil pressure system is working well.

1996 Ford 300 six cylinder loses oil pressure when engine warms up


first you will have to say what the oil pressure is cold, idle and 2000 rpms and then hot idle and 2000 rpms before a decision to advise about a rebuild can be made
there are many reasons oil pressure can drop and not all require a rebuild

Oil pressure fluxuwaits


This generally means one of two things. main bearings are worn or oil pump failing.
If the oil pressure is around 30 during idle and 45-50 during cruise then this would
not be any cause for concern. but if it is dropping while climbing hills, (like in the mountains)
then mains are worn. hope this is helpful.

2000 Grand Cherokee V8: Cold start Oil Pressure is good at 600 rpm. Gauge drops to 0 in 2/10 mile as rpm increases to 2000. Warning light and bell comes on. Gauge varies between 0 and 40 depending on...


Replace the oil pressure sending unit its giveing a false reading . The problem is when the engine is cold the oil pressure is low and it takes a little time to build up whem cranking the engine and that sends a signal to the computer PCM /VCM what ever but your 40 to 60 lbs oil pressure is graet its ideal .The unit switches when the oil pressure is high enough to trip the switch inside the sending unit and that is sent to the vehicle control module

Oil pressure drops, metal shavings, and somehow my oil level incr


My truck does the same thing, pressure never drops to 0 but drops low, replaced the oil pressure sensor and same thing happened. My oil is always black and has a lot of metal in it, next time you change your oil, pour a quart of transmission fluid into the oil and let it run for 10 minutes or so, this should thin out the oil and possibly unclog some of the ports that may be gummed up. What could have happened with the dipstick is that the old oil was too nasty to drain all the way, with the fresh oil it could have thinned out and raised the level, try the transmission fluid trick and see what happens, next possibility is to have the engine scoped to see whats going on inside

Oil pressurer loss ford bronco2


It's normal for the oil pressure to fall off at idle as it gets warmer because the oil gets thinner. It should operate between about 20 and 60 lbs. If it drops below 10 lbs at hot idle, you may have some bearing wear or a worn pump.
