My check engine light came on my 02 SantaFe, what can i do?

THE CRANK SENSOR IS LOCATED ON THE ENGINE BLOCK NEAR TRANSMISION BUT CALL YOUR DEALER THIS TRUCK HAVE A RECALL FOR THE SENSOR

neither have i to be honest ,i change oil filter every third oil change on my regular customers cars with a oil change every 6000km or so ,never a problem and i have often changed a filter on some cars without changing teh oil where the metal cannister has started leaking

change your oil every 3000 miles or 6 months witch ever comes first and change it more often if you drive in really dusty or dirty conditions.

it is probably going into a fail safe mode, get it to a dealer and have it scanned for dtc's

Hi:
All of the engines in Hyundai santa fe are interference engines, so you should regularly change your timing belt. The timing belt also drives the water pump, so it is always a good idea to change that too, if you have the engine apart for the timing belt. Here is a link to check out!

Carfixer 1 is right. The Hyundai engine is called an interference engine, which means that when the timing belt breaks, it will allow the valves to hit the pistons and you will ruin your engine.

Do yourself a favor and replace the belt at recommended intervals. If you are past the 60k mark, have it done right away and save yourself a lot of grief and expense.

Difficult question with all the variables involved. I'll start by saying the Santa Fe is a decent vehicle, and has the potential to last a long time (many miles). However, as with any vehicle, how has it been driven and maintained? If you purchased it new, drove it 'gently' (no racing, wild off road driving, starting it on a 0 degree day and revving the engine to high rpm, etc) maintained it well (fluid and filter changes on a regular basis, topping off fluids (not letting the oil go down a quart before adding- top it off when its only down 1/2 qt at most), fixing anything that starts to go (before a small problem becomes a big one), you could probably get 200k miles or more out the vehicle. What kind of driving do you do? Highway mostly? The # of miles over the life of the vehicle would be highest, if you do short drives around the city, that is tougher on a car, total miles of the life of the vehicle would be less. If you bought the car used, there is the big unknown factor--how did the previous owner(s) take care of the car? Was it owned by a little old lady that only drove it to church on Sunday, resulting in 1k miles driven a year? Sounds great, but letting a car sit w/out driving is actually bad for the car. Has the car been kept clean? If it's driven in an area w/ snow, is the vehicle washed often to remove road salt? Some cars sheet metal fails before the engine and tranny do because of corrosive road salt. So, to answer your question, 'it depends..." Good luck.

I faulty Idle Air Control valve (IAC) can cause these specific symptoms. You could try diconnecting the IAC valve (usually near the throttle body) and regulating the idle yourself. If the fluctuations go away and you are able to hold a constant idle position with the gas pedal (if vehicle will start), the IAC is the problem.

Lift your Hyundai Santa Fe using a jack and then place the car on jack stands. If you don't have jack stands, drive the car onto a set of wheel ramps.
Pop the hood and remove the dipstick and oil filler cap. The dipstick is near the front engine compartment with the oil filler nearby.
Gather an oil drip pan, a 17-mm wrench, oil filter wrench, cleaning cloths and a new oil filter. Slide under your Santa Fe.

Change the Oil

• Locate the oil filter and oil drain plug underneath the car. The drain plug is on the bottom of the oil pan, and the filter is to the side of the oil pan.
• Remove the oil drain plug using the 17mm wrench. Pull the plug out quickly and let the oil drain for 10 to 15 minutes. Check the gaskets and threads for damage. Replace these components, if necessary.
• Take off the oil filter using an oil filter wrench. Dump the old oil into the oil drip pan and put on the new oil filter. Tighten the oil filter by hand, and then replace the oil drain plug using the wrench. Clean off the excess oil.
• Go under the hood and add oil. Turn on the engine and check the oil pressure gauge to make sure it rises. Let your Santa Fe run for a minute.
• Lower your Hyundai Santa Fe and turn off the engine. Take an oil reading on the dipstick. If the oil level isn't at full, add a bit more oil.

oil change lamp will come about 3000 miles but the check engine has dto do with the engine sensors and preformance.have the comouter scanned for engine codes.let me know the codes. if you have a auto zone in your area they will scan it for free just write down the numbers.
