SOURCE: rattling from the engine when I start the 2006 V6 Sonata

Do you have the air conditioning on when you hear this rattle? If so, it could the clutch for the a/c compressor. You may also want to check the status of the idler pulley on the serpentine belt. Hope this helped and best wishes.

SOURCE: Hyundai Sonata 2006 - Check Engine light came on.

"Fuel system too lean at idle". It's an air/fuel ratio that is not correct, possibly a vacuum leak somewhere. Or a leaky exhaust pipe. Could be related to intake manifold gasket. Somewhere, air is getting into the engine.

I suggest taking it back to the dealer under warranty. I think Hyundai is 10yr./100k for the original owner. 5yr./50k if not. Ask first if covered, and ask why not id not covered.

Several things could be the cause:- Before looking at the list below ensure that the throttle body interior is spotlessly clean and that the air ducting and all vacuum lines are free of leaks. Check all relays and fuses On the fuel line on the engine there is Shrader valve (like the one for the tire). It is possible to check fuel pressure at this point with a gauge. If there is insufficient pressure here then this points to a possible fault with either the fuel pump, its relay or its fuse.
1) Idle air control - The idle air control is closely associated with the throttle body. Its function is to bleed air to the inlet manifold past the closed throttle plate. There are teo types of throttle control a) a motor that opens the throttle plate a tiny amount b) an auxiliary passage opened by a valve around the closed throttle plate How to check? Physically remove the IACV but keep the electrical connection to it. Turn the engine on and examine the IACV valve movement in response to additional loads (power steering inputs etc). The valve should open and close according to demand causing perceptible change in engine speed with increased power demand being made on the engine.

The electrical connector to the IACV can have 2 or 4 pins:-

2 pins: resistance between pins should about 10 OHMS +/- 3 OHMS. Resistance between either of the pins and the valve body is greater than 10,000 OHMS

4 pins: resistance between diagonally positioned pins should be about 20 OHMS

2) Throttle position sensor - Sometimes with ignition off it is possible to reset the TPS by depressing the accelerator fully and releasing quickly. Ignition might be enhanced by depressing the the throttle slowly. If the car cuts out if the accelerator is depressed quickly this is another indicator of a bad TPS. How to check? The socket for electrical connection with the TPS has 3 pins, one for 'ground', one for 5 volts 'reference' and a third (generally the middle one) for 'signal' output. Back probe the signal pin in the connector to the TPS. Attach the positive lead of a voltmeter to the probe and measure the voltage output as the throttle plate is rotated. If working correctly the meter should show a voltage consistent with the throttle position from approximately 1 volt when closed and 5 volts when fully open. What is looked for is smooth voltage increase with throttle change. If there are drop outs in the transition or that there is no transition seen the TPS is faulty.
3) cam or crank sensor faults - 2 pin socket (magnetic - sine wave output). One pin is 'ground' the other is 'signal'. A voltmeter set to 2 volts AC should measure a signal in the 0.2 to 2 volts range on the 'signal' pin.

3 pin socket (Hall effect, magneto - square wave form output). One pin is 'reference' (5volts), one pin is 'ground' and the third pin is 'signal'. A DC voltage should be detectable in the 0.5 to 1.5 volt range from the 'signal' pin.

It is important that the voltage measurement take place at start up when the engine is cold and again, 20 minutes later, when the engine has fully warmed up to operating temperature. Often the voltage output from faulty sensors declines with temperature rise. I appreciate here that due to a lack of starting in your case it just might be impossible to check the 'warmed up' situation. I hope this helps.

Hello
Unfortunately you most have a problem with the flex-plate (flywheel on manual transmissions) it is either bent or cracked (common) or the teeth on the flex-plate are damaged or both, it is the only thing that causes this problem other than the starter drive being defective, and since you indicated the starter has been replaced and the problem still exists then the flex-plate is the problem. To change the flex-plate the transmission must be removed from the truck, to do this disconnect the negative battery cable then remove the starter and support the transmission with a floor jack, then remove the drive shaft from the truck, next remove the wire connector to the transmission and the shift cable and the transmission cooler lines, drop the rear mount that supports the transmission and move it out of the way, remove the lower cover over the flex-plate and remove the bolts that secure the flex plate to the Torque Converter (you will need to rotate the engine to get the bolts out) next lower the rear of the transmission down far enough to see and remove the bolts that secure the transmission to the engine block, make sure in on last check that all is disconnected from the transmission and drop the transmission down and pull it out from under the car, install the new flex plate and torque the bolts to 45 foot pounds, use new bolts.

Could be a fuel problem. I would have someone check fuel pressure before and after cranking the engine. You may be loosing some fuel pressure back into the tank when the engine is off.

leave car with them ( or reputable tech) to drive as you did when you did and replicate the problem....a good tech should find the code and its relation to vehicle speed/temp/gear selected..a/c on etc to close gap on issue....high speed codes often catalytic converter/O2 sensor/VSS ...or otehr related..does it run different when showing codes?
