It sounds like the oil sending unit which is an inexpensive part and simple to replace it should be located between radiator and engine on the side of the oil pan

It's your alternator. I would get it fixed asap or you will be stranded. My mechanic said that mine caught a small fire when he pulled it in the garage. Auto Zone has rebuilt ones.

SOURCE: the oil pressure light goes on and off intermittently.

I had a similar problem with my 2003 Sante Fe (intermittant problem, the light went off when I accelerated). I took it to the dealership. They looked for a bad send oil switch (not the problem) as well as some other possible culprits but could not, at first, find what was causing the light to come on (but they did confirm that I had low oil pressure). So, they took the engine apart. What it was was the pan was "dented" upwards, so that less oil was able to come in. It wasn't the bearings. It wasn't the crank case. It wasn't the oil pump. So, they fixed the dent, put everthing back together and . . .it worked! The light went off and stayed off. It cost $337 in labor. I was very very very relieved.

(Apologies if this explanation is hard to follow-I'm no mechanic and am basing my response on my understanding of the mechanic's explanation).

Yep!.. Typical with an engine cylinder misfire. Inspect the plug and ignition wire, especially the insulator. If you see a 'christmas tree' pattern on the insulator, that's where your problem is.

My dashboard lights (battery emergency brake light & air bags) are flashing on my dashboard while driving but go out when I come to a stop on my 2001 santa fe


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

e-brake pedal should go farther- is either out of adjustment or cable frozen- secondly sounds like only front brakes receiving enough pressure to "activate" properly- bleed all four brakes starting rear pass,then rear drive ,then front pass, then front drive- use plenty of fluid- bleed till fluid is clean without bubbles- will that long at first- this will insure not bubbles and no moisture- if a pro valve dies,you would have more problems- pedal would be really soft,would have both a brake light and abs warning lights

THe problem can only really be with the clutch master cylinder. What you describe sounds like the master cylinder is not relieving pressure and this is building up in the salve cylinder, applying pressure to the pressure place and causing the clutch to slip. Can you make the problem go away even temporarily, if you open the bleed screw on the slave cylinder? You say that the free play is correct, but is the master cylinder returning fully to its released position?

if you talking brakes not clutch. you can pump the brakes all day long and they don't build pressure and you not losing fluids the master is out. now if you pump them up and they are rock hard your hydrabooster is out.now if your mechanically incline you can order a master cylinder rebuild kit for like 20-30 bucks which is basically orings from local parts store and only tools you need are snapring pliers. or you can change the master ,bench bleed it first then bleed out the rr,lr,rf,lf in that order.hope i help.all under 100 bucks

this sounds like the clutch slave is goin out, this unit is on the outside of the transmission. Possibly losing pressure!! Your transmission does not use transmission fluid, but instead gear oil. Have the following checked:
1. Clutch Slave (possibly worn)-this will cause soft or hard clutch pedal feel, slipping clutch, unintended clutch release, hard gear engagement, no/insufficient clutch movement.

*2. Clutch pedal Mounting Plate (possibly cracked)-this will cause improper gear engagement, hard gear engagement, soft pedal feel, insufficient clutch movement.

*this plate is located above the clutch pedal itself, apply pressure on the pedal with one hand while inspecting the plate for fatigue cracks(use a bright flashlight). This is very common on these models. This problem will eventually get worst and most mechanics never figure this out.

Car wont start


when you press the brake pedal the brake master cylinder vacuum booster takes vacuum away from the engine and that slows the idle speed just enough to trigger the low pressure oil light. Pull the oil pressure sending unit out and hook up an oil pressure test gage, if the pressure is above 15 PSI hot engine idle in drive replace the oil pressure sending unit.
