SOURCE: oil pressure guage dropping

Sounds like the sensor is failing.Have oil pressure checked with a mechanical gage to confirm. A new sensor or wiring repair is allot cheaper then a new engine!!

SOURCE: ABS

The code scanner that you need is called ODBII code reader with ABS, and it works in the same way as the one that you connect to the car computer module (ECU) to read codes when the check engine light comes on, but the cheap ones that you can buy from $50 do not have the ABS brake scan function.

If the problem is the ABS, then it is often a wiring to abs problem, or a defective ABS control module, a scan reading is necessary to know what the problem is.

Below few examples of Code reader with ABS:

SOURCE: service 4WD light illuminates on the dashboard message box

this is most commonly a electrical problem, does the speedometer read out correctly? if not it may be depending on if this is a Autotrak model, one f the two speeed sensors, or the acuator on the front diff, put the truck in 4wd, check the front dirveline to make sure it is engaing, if not your problem is in the t-case, if it does then move to the tires, if they are not engaged you have a problem with the actuator.

in most cases i have found the actuall 2wd 4wd switch to be the problem if you find that the switch is acting slow or you need to select the gear a few times before it shifts, then replace it these are very faulty

The low oil pressure warning lamp will illuminate anytime the ignition switch is turned to the ON position without the engine running. When the engine is running, the light also illuminates if the engine oil pressure drops below a safe oil pressure level. To test the system, perform the following:
If the oil pressure light does not work, perform the following:
  1. Turn the ignition switch to the ON position.
  2. If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
  3. If the wire at the connector checks out OK, pull the connector loose from the switch and, with a jumper wire, ground the connector to the engine.
  4. With the ignition switch turned to the ON position, check the warning lamp. If the lamp lights, make sure the oil pressure switch is properly grounded in the cylinder block, and if so replace the oil pressure switch. If the lamp still fails to light, check for a burned out lamp or disconnected socket in the instrument cluster.
To diagnose an oil pressure light that stays on, perform the following:
  1. Check the engine oil level and top off as necessary. If the engine was 2 or more quarts low on oil, test start the engine after topping off the oil level and recheck the oil pressure light operation. If the light stays on, stop the engine immediately and go to the next step.
  2. Disconnect the wire at the sending unit, then turn the ignition switch to theON position. If the light remains on, check the wire from the sending unit to the gauge for being shorted to ground and repair as necessary. If the light goes out, turn the ignition switch OFF and go to the next step.
  3. Replace the oil pressure sending switch with a known good switch.
  4. Start the engine and check the oil pressure light operation. If the light stays on with the engine running, stop the engine immediately to avoid severe engine damage until the cause of the problem can be determined.

WARNING
If the oil pressure light remains on while the engine is started, stop the engine immediately. Do not operate the engine until the cause of the problem can be determined. Operating an engine with low oil pressure will cause severe internal damage.

Possible causes for an oil pressure light to stay on are:


Pinched or grounded sensor wireDefective oil pressure sending unitRestricted or severely leaking oil filterExcessive internal engine bearing clearance.Insufficient or severely contaminated engine oilBlocked oil pump pickup screen or severely worn oil pump

Why would the oil light stay on?


That depends on the type of oil warning light being displayed. There are 2 types of warning lights

1. Low oil pressure light which all cars have
2. low oil level light which some cars have.

Low OIL PRESSURE warning means the oil pressure is below minimum and when this happens there will be insufficient lubrication of many engine parts because sufficient oil cannot get to all parts of the engine it is required to lubricate. Until the cause is identified and rectified the warning light will remain. If you run your engine with low oil pressure you will cause expensive damage to internal engine components.

Low OIL LEVEL warning means the oil in the sump has dropped to a dangerously low level (which may be due to an oil leak or abnormal oil consumption by the engine.) This warning means the oil level needs to be topped up and the warning will stay displayed until you top up the oil. Running the engine with low oil will cause expensive engine damage.
Since it is a 2 minute job, Oil levels should be checked fortnightly as a minimum, together with radiator coolant and power steering fluid levels, if you run the car most days each week as most people do.

It is possible for a warning light to remain displayed when the cause has been dealt with because there is a problem with the sender unit. However it needs to be established with alternative checks that the problem has been fixed before investigating if there is a problem with the warning light itself.

What are the steps in changing the oil in a 1986 Lincoln Town Car


1) Purchase appropriate oil filter, sump drain bung washer and chosen engine oil.
2) Prepare an oil pan, sump bung wrench and oil filter removal tool (check access to oil filter to be sure that your tool is suitable.)
3) Run the engine until its warm to hot.
4) With the car jacked up and secured, remove engine oil filler cap and remove engine oil sump drain bung and allow oil to flow out into your drain pan. Keep an eye on your oil and make sure it doesn't overflow from your drain pan.

5) Refit sump bung with new washer and tighten. Do not over-tighten, and be especially careful when tightening into an alluminium sump.


6) Remove oil filter. Oil will flow out from this filter when removing, so your drain pan will need to be under the filter housing when removing.


7) Run a smear of clean engine oil around the filter rubber seal and refit new filter. Tighten hand tight only. Do NOT crank this filter super tight as you may damage the rubber seal and even the filter casing which can impede oil flow.


8) Refill engine with proper quantity of oil. If you cannot find how much oil your engine is supposed to take, then refill with the same quantity of oil which you drained out.


9) Restart the engine while checking the oil pressure warning light on the dash. The warning light may stay on for three or four seconds and then go out. If this light stays on for longer, then stop your engine and check for oil leaks at the filter body and sump drain bung.


10) Once the engine oil pressure warning light is off after starting, stop the engine and check the engine oil level (with vehicle on the flat and off any axle stands.)


11) Road test the vehicle, driving it for a mile or two before re-checking for oil leaks under the engine bay and engine oil quantity.

Oil pressure warning on 2001 Volvo v70 with 220Km


2 things i would do professionally first. 1. change the oil using a higher weight and a volvo oil filter(there is a difference) 2. have a "wet" gauge installed at the oil pressure sending unit to verify oil pressure from cold to warm. a "wet" gauge is a gauge that reads actuall oil pressure and not the use of electronics. it is usually very acurate. if the oilp pressure still drops, then you are looking at an oil pump issue most likely.

When i turn off the car sometimes the oil light comes on


Then what? It stays on forever. Comes on for just a second? You watch it till it goes out----you know just like the refrigerator light. But how do you know it's off when the door is closed?
Man, you could spend you whole day at this.
If the oil light comes on after it's running......now there's a problem.

Clearly not enough info to comment on this. Who cares if the light comes on when the engine is off. It's not running, it doesn't need oil.Quick, when the motor is off, and you've reached your destination. Unass the seat.

Gauges say no pressure in engine 1995 vw golf


Get someone to check oil pressure with a mechanical gauge, to verify whether you have oil pressure or not. These engine/vehicles, have 2 warning sensors & a control module in the instrument panel. Once you know you have pressure for sure, then you can proceed from there.
