SOURCE: oil control valve

on the lower front of the cyl head right where the thermostat is a 14 mm bolt remove that bolt and there will be a screen filter for the ocv if clogged it will reduce oil pressure to the ocv and give you a p0010 or p0011 code clean screen replace clear code all should be good

SOURCE: Hyundai Sonata 2002 idle at high RPM and accelerate 40-45 MPH

Look for a vacuum leak somewhere. This is the most common problem for a high idle.

SOURCE: High Idle when shifting. It goes up and down idle on it own.

dear friend-the hyundai products has the future of returning to idle slowly so any changes wil not bring it down quicker unless you can find away to confuse the ecu.

Code p0507 Hyundai Santa fe cost to repair


Jena: According to http://www.obd-codes.com/p0507: " P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.
Potential Symptoms Most likely you'll notice the idle speed is higher than normal. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes A P0507 DTC trouble code may be caused by one or more of the following:
  • A vacuum leak
  • Leaking air intake after the throttle body
  • EGR valve leaking vacuum
  • A faulty positive crankcase ventilation (PCV) valve
  • Damaged/failed/dirty throttle body
  • Failed EVAP system
  • Failed IAC (idle air controller) or faulty IAC circuit
Possible Solutions This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect the intake air system for air or vacuum leaks and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns.
If you have an advanced scan tool that can interact with the car, command the idle higher and lower to see if the engine responds appropriately. Also check the PCV valve to see if it's blocked and needs to be replaced. Check the IAC (idle air controller) if equipped, verify it's operation. If available, try swapping in a new throttle body to see if that fixes the problem. On Nissan Altimas and possibly other vehicles the problem may be fixed by having the dealer perform an idle air relearn procedure, or other relearn procedures."
So, Jena, you start with the cheapest possible solutions. Go to YouTube and look up how to detect a vacuum leak. https://www.youtube.com/watch?v=9CPqbaSgcok Buy a can of throttle body cleaner and get one of the auto store people to show you how to get to the throttle body (basically you use a screwdriver and take off the huge air hose). Then clean the throttle body. If you don't get rid of the problem, watch the YouTube video on how to clean the EGR Valve. https://www.youtube.com/watch?v=TB1E9opb87Y While you are at the auto parts store, you will probably want to buy an PCV valve. This may solve your problem even without a mechanic! :)

I hear big vacuum leak on 2001 elantra not any hoses


If you can "hear" a vacuum leak then the performance of the car would be greatly affected and the engine would idle much higher than normal. Normal idle speed is around 800-1000 rpm, Check you dash tachometer. If you have a vacuum leak the idle will go up to 1200-1500 rpm.
There are lots of places beside hoses that can leak vacuum such as the EGR valve or around intake manifold. But check that rpm's first to confirm what you are hearing is a vacuum leak.
You can also purchase a vacuum gauge form your local auto parts store. they cost around $20.00+. The gauge should read a steady 15-20", if less, then a leak is indicated

I have a 2001 hyundia elantra problem i am having is weather it has just been started or is up to operating temp. it will rev to almost 3k then down to 1500then back up to 3k then back down i believ this...


If this is something that occured all of the sudden, unplug the vacuum hose from the vacuum booster behind the brake master cylinder. Plug the hose and see if the idle settles down. If it does, replace the brake booster. Let me know, also, what codes have been pulled?

What does the coe p0507 mean caddy deville 2001


Idle Air Control System RPM Higher than expected. The computer is detecting an idle speed higher than what it should be. A vacuum leak perhaps...EGR valve, faulty PCV valve, throttle body, EVAP system, idle air controller or circuit. Check for vacuum leaks.
