check the automatic shifter lock that you press in when you go to shift. if that is not all the way out it will prevent it for coming out.

Check the resistance on the injectors. You may have bad injectors thats why it is idling rough. Use a multimeter to check the resistance. Normally the reading should be anywhere from 12 ohms to 20 ohms. Extremely high resistance indicate a bad injector. Do not energize the injectors with 12 volts DC. You will burn them up. They are designed to operate on pulsating current.

Faulty Airbag sensor

Needs to be diagnosed by a man with a laptop

They may be able to reset it for you

Passenger compartment relay box next the ECM
you will see 5 relay
2 to the left & 1 in the middle & 2 to the right

The one in the middle is the fuel pump relay

Hi:
P0734 is a transmission code, and you usually have some sort of driveability issues along with it. If your transmission fluid is full, It is best to have it checked out by a transmission shop

It has to be reset by a scan tool, such as those at a shop or dealership. You can clear a lot of different codes by unhooking the battery, but not an airbag fault light.

hi from uk have read your symptoms and from what you have described your starting /failure to turn engine ? 1st have you checked the leads to the starter motor are secure ? especially the single thin wire that fits to the starter solenoid on a spade connector ensure it is fully clipped on ? if ok ? may i suggest you try this ?= connect a single jump lead to the earth connector post on battery then the other end of jump lead to a suitable earth connection on the engine then try starter ifthis works your problem is a faulty/corroded or loose earth connection from the battery to the chassis/andon to engine usually connected to a bolt on point where trans connects to engine ? for info i have come across this problem a few times on accents and found that for some reason the thin wire connected to starter solenoid had come loose due to not clipped fully on also the earth lead from batteries have not had clean/securety loose bolt hope this helps and wish you luck

Try replacing the speed sensor on the transmission. My son had the same problem with his 98 Elantra.

that code P0335 = No signal of crankshaft position sensor to ECM during cranking. have to check all the wires to this sensor

dear friend-it sounds to me that the syncronising ring can be broken,which means you have to remove the gearbox.

When I put a Cd in the cd player it says error 42 Hyundai azera 2006

Hi, it might be that the indicator circuit fuse has blown. You will need to look at the fuses. If there are no fuses blown it might be that the indicator switch is faulty

sounds as if you may have an ac clutch freezing up on you. If it works fine while ac is off and frezes when on. bad clutch.

ECU= Electronic Control unit. This is what controls all the engine electronics. All the sensors on the engine and other things are routed through the part. What it does is tells the engine how to run. Each sensor plays a specific role. The ECU reads how much are the engine is getting, tells the engine how much gas it needs, etc. Try digging around a salvage and finding a new ECU. Swap it out, and if it is still blowing the ECU fuse then you need to start looking for shorts.

There are 2 possibilities.

1. Since the clutch is hydraulic, some particle is jamming the rod-piston movement, hene the clutch lever is jammed(if using manual transmission)
2. The springs which press the clutch plate to the engine(cam) are either brken off, meaning the clutch remains engaged all the time and since the hydraulics are not able to push them apart(release the clutch)-applicable for auto or manual trensmission.............. ..sodeep

that smell is probabbly caused by the catalyzer breaking up the particles of your exhaust...the problem with the battery has no connection with ur catalyzer, have it checked by a tecnician

under the driver side dash is the ECM, just above it should be a small cluster of relays. i forget which one is fuel pump, but if you plunk them out one at a time and listen for fuel pump whirring when you put key in the on position you can isolate which one it is.
also, are we totally sure this is a fuel problem?...

Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.Whenever the 'CHECK ENGINE' (Service Engine Soon) light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE the problem and perhaps eventually fix the problem.

No, but they do have sensors..

above the main fuse box under the dash if it still works or makes a noise turn indicater on to see which relay it is there will be a few relays there
