I don't know how you checked oil sensor, but it sounds like it's bad if engine is not ticking. There's 2 "oil sensors" on car - 1 is level which is on oil pan and other is pressure sensor on motor. Refer to (enter your car specs) and you'll find exploded views of engine components. Also refer to or Pelican for tips & tech info.

Ford aerostar troubleshooting

It could be any number of things, most likely cause is you have a oil sending unit that is wore out and giving false readings. Either buy a new sending unit and change it out or hook an oil pressure tester to your engine and check the oil pressure.
I'd buy a new sensor and replace it myself, because the vehicle is 23 years old and probably the original sending unit, besides the oil sending unit has to be removed in order to check pressure with mechanical gauge anyway.

2002 dodge intrepid gets to operating temp oil light comes on tep gets high runs rough and dies no ticks runs smooth until it reaches operating temp

put an engine flush in first . run the engine on tick over .till oil is hot then drain it. do an oil and filter change may have a build up of carbon in the engine .the flush should deal with that .use 20/40 oil .

My 2007 chevy uplander's cooling fan kicks on the moment I start the engine, stops when I turn off the engine, temp gauge reads normal, check engine light is not on, thermostat is ok, flushed radiator,...

Hi Bajil, Have a diagnostic scan carried out and have the coolant temperature sensor and relay inspected for correct operation. It sounds as if a cable has become disconnected or that the operating circuit has become defective. The cooling circuit operation is correct when the fan operates when the engine temperature raises a fraction above normal. The fan will run for a number of seconds and then switch off, thereby maintaining the 'normal' operating temperature. Regards John

Oil light flickering on dash

Check/confirm the following (on 1987 models the wire harness in the engine bay is a known defect and the insulation is very prone to premature failure):
1) Oil level/condition/type of oil (15W40 is the general specified oil for these cars). To rule out low engine oil pressure have the system pressure checked by an accurate gauge installed in place of the oil pressure switch. The switch itself is screwed into the block, bottom left side if you are looking at the engine from under the hood (on the exhaust side). The sensor is indeed a switch - spring-loaded and normally closed (open when there is pressure).
2) The oil pressure switch wire is run around the front of the engine, secured by a sheath and clips. Check to ensure the insulation of the wire is intact and not chafing anywhere - trace it out carefully. It's a one-wire design, grounded by the threads of the sensor into the block. A good test is to disconnect the wire at the sensor and drive the car. If the light is still flickering, you have an intermittent short.
3) If the oil level is normal, its condition is good and of the correct weight, it is entirely possible that the oil pump strainer is clogged. This results in low oil pressure. The other possibility is that the oil pressure relief valve in the oil pump is sticking open. In either instance (provided they are true), the oil pump should be cleaned or replaced - something that is a formidable job as removal of the oil pan involves either pulling the engine or dropping out the subframe and related components. Do not use engine oil flush treatments - they tend to overload the oil filter and cause the oil pump pressure relief valve to open and could lead to serious engine damage.

These are the usual things I would check first before condemning the engine. Loss of power, rough running and metallic knocking/thumping sounds would point towards an engine rebuild, especially if they are all present at the same time. But if the engine is running well and quietly, the turbo spools and is also quiet, then start with the aforementioned electrical tests of the oil pressure sensor switch and go from there.

At 28,066 dealer oil change. At 28,778 dealer flushed engine to remove sludge build up and changed oil. At 30,835 miles inspection, dealer flushed engine to clean out sludge and changed oil. At 34,630...

First dealer was NOT doing you any justice. Next oil change run a can of GUNK engine flush let idle 5-10 mins then change Oil & Filter and use a good oil like Castrol or Valvoline 10w-30. You won't have "supposed" sludge build up.

You can fiddle with thiis and check oil pressures but best is sump off, thorough clean, teardown the pump thoroughly clean it and pickup and replace it if any wear or the pressure releif spring is weak.You have given no mileage and no information on the oil used nor whether in a really hot area or 'where'?..there are several considerations ranging even into worn bearings...Of course with acceleration motor speed increases oil pressure...that's why light goes out (unlikely but possible the sender unit is faulty...but try replacement of that first if you want...) It doesn't take a lot of pump wear to cavitiate and drop oil pressures.

Likely you set that code by removing the can usually clear it by disconnecting the battery or if you keep driving it I believe eventually it will go out when the computer cycles through and finds it is now OK.

Flickering oil light

This could be two unassociated problems; the flickering oil light can indicate that the pressure sensor for the idiot light is failing- this is not uncommon, the other can be a failed temperature sensor sensor on the main radiator. 
The low oil pressure condition may also be indicative of a worn engine part or parts. It would make sense to have the actual oil pressure checked in a shop to see if it is in the normal range which should lay between ~30 & 60 pounds depending on engine RPMs and engine temperature. The idiot lights trigger at around 4-5 pounds and this is really pretty late for a warning; if the pressure is actually that low, not only lubrication is too little but the cooling effect of the circulating oil is inadequate.
If it was my car, I would replace both sensors before getting too worried. The cost of these together (parts only) should be well under $50 US.

Jiffy lupe said i need engine flush for my 2002 Jeep Liberty

No, this is not normal. if you have coolant or water leaking into the engine piston chambers, you will need a head gasket not an engine flush. if you open the oil cap to add oil to the engine and you see a lot of gunk under the cap, then its time for that flush. I would be concern about the more serious issue and that is that there is coolant or water leaking into the combustion chambers. this is a sign of a bad head gasket.

please rate and god bless..
