there is a schedule in your owners manual

I would check your fuses first,if all are good , there is a switch in your shift console that triggers the back up lights to come on, this is not easy to get to so take your time

Most of the time this needs to be done at the dealer, unless it came with programing instructions that worked your stuck going to the dealer, sorry

Buy a cheap shop manual to get complete valve adjust procedure.

Darren, this is from a 2007. But give it a look.

take your car to auto zone or any parts store that will run the check engine light test for free. See if they can pull a code telling you what is causing the light to come on.if there is no code no one can tell whats wrong until it reappers if this is helpful please leave good feed back

Check the fuse to the radio.

With your key in the ignition, do not turn it, open the fuse panel by the drivers side door, pull out the 30amp P/CONN fuse at the very bottom (mine was in a weird yellow casing) then plug it back in. The disk drive of the radio should make a noise. Now start your Tuscon and turn on your radio.

have you checked in the coolant , it is the only other place it can go , if it has you have a cracked engine block

the electronic BEEPER may have failed , take to a hyundai dealer for there diagnosis

Could be be clogged fuel filter or air filter or poor output from fuel pump. Low fuel pressure etc will cause it to "starve" for fuel. Clogged air filters will do similar thing causing it to choke for air. You said it loses power, does that mean it stops running and the engine dies or is it just not giving you as much acceleration as you need. Could also be the drivetrain like torque converter or transmission depending on the model if it is automatic. If it is standard then it would not sound like a drivetrain problem, my first suggestion if to get your fuel filters cleaned and then have a fuel system cleaning done. They will physically clean the throttle body and add a solution to the intake while it is running as well as pour an additive into the fuel tank. First things first, fuel system cleaning, then fuel filter/s. Then check fuel pressure output.

what make you feel like they need adjusting,i cant remember rite now but if you hear them check your oil pressure i had a problem with one and i had to change the oil pump

transfer case 1.5L; Diamond ATF SP-II (if u have 4wd) automatic transmission from 10.5L up to 11.7L; Dexron II

This error means Exhaust Gas Recirculation Flow Insufficient Detected.

You can deatils on the following site http://www.permoveo.ltd.uk/tabid/122/OBD-Error-Code/P0401/Diagnostics/Hyundai/Default.aspx

but for convenience I have reproduced that information here:

Generic OBD Error Code Details for P0401 Exhaust Gas Recirculation Flow Insufficient Detected What does this mean? OBD Code P0401refers to
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR. SymptomsPossible sumptoms of OBD code P0401
You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms. CausesPossible causes of OBD code P0401
A code P0401 most likely means one or more of the following has happened: •The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced•There is a blockage in the EGR (tube), most likely carbon buildup •The EGR valve is faulty •The EGR valve may not be opening due to a lack of vaccuum Possible SolutionsIn fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit. •Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open •Clean out the EGR valve and/or tubing to remove deposits•Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)•Replace the DPFE sensor (with a good quality / OEM one)•Replace the EGR valve Related CodesP0400 P0402 P0403

Need to check the following: Check if cam belt not broken or stripped 1. Pull out the coil pack and check if plugs are firing. 2. Check for fuel pressure. (3.4 bar) 3. Check compression (12.6 to 14.2 bar) 4. Check if cam and crank sensor are fine 5. Need to carry out machine test.
