Okay diagnostics 101:
1) Do the spark plugs have spark?
2) Does the vehicle have air?, i.e. is the air-filter condition okay?3) Does the vehicle have fuel?, i/e/ is the fuel pump operational and is the filter clogged?
If the vehicle has all of these three things, then either the mixture of air and fuel is faulty, or the spark timing is faulty.
A common issue on a vehicle if it doesn't have an issue with the supply of all of those things is the MAF sensor or the Manifold pressure sensor, which can give false readings to the ECU and cause the ECU to provide an incorrect fuel injection, resulting in an incorrect fuel to air ratio.
Please let me know how your diagnostics works out.

SOURCE: 2005 Dodge Stratus ? Camshaft Position Sensor causing problems (I

I had the same problem with my '05 Stratus SXT 2.4 DOHC. I've replaced the cam pos sensor and it seems to be running fine right now. On the Dodge forums a lot of the guys say that you need to replace the crank pos sensor too. I've bought one of those just in case it comes back again. Hope this helps.

SOURCE: error code po340 for a 2002 hyundai elantra

Here is what I could find on your P0340 error code:
CausesA code P0340 could mean one or more of the following has happened:

  • a wire or connector in the circuit could be grounded/shorted/broken
  • the camshaft position sensor may have failed
  • the PCM may have failed
  • there exists an open circuit
  • the crankshaft position sensor may have failed
Possible SolutionsWith a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required
Sounds like since you have replaced both the camshaft and crank shaft sensors you need to look at the PCM.  Go down the line of possible solutions and don't replace the PCM unless nothing else works obviously.  I hope this helps but it looks like you are looking at getting a new PCM.  Good luck.  Thanks for rating my response and for using FixYa!

SOURCE: crankshaft position sensor location

Hello. One way to check if it is working is when you try to start the car does the needle move on you tac? If not then your crank sensor is more then likely the problem. It is located on the backside of the engine under the intake manifold. If is in about the center of the block. There will be a 10mm bolt holding the sensor in. If you decide to change it yourself (not to terrible of a job) unplug the sensor, remove the bolt and spin it back and forth slightly while pulling it out. It may be stoburn and you might have to work at it for a little bit (not a done of room) but it will come. When it's out the sensor will be shaped kind of like an L. I have changed a few of these over time and they can be a little stoburn. To install just reverse the process.

SOURCE: DTC - PO340, PO325

My Nissan micro 2004 model just stopped in the middle of the road one day then the engine management light came on, anyway took it to my local garage TWK Thomas who said it was a cam shaft sensor problem. OK so sensor was put on, engine management light went off for two days only. So went back to the garage they said that another sensor should be fitted on the opposite side. And then the problem should be rectified, but i had given the £160 for this problem to be fixed the first time. I decided it was time to take it to another garage Nis Tec they put it on the computer and a code po340 came up would this mean another sensor or the cam chain has stretched please help. ...claire

That code would have been "camshaft position sensor". They may have replaced the old one with a faulty new one, which might account for the blown fuses. Have them try unplugging it to see if it stops blowing fuses. If it does... have them replace that sensor again with another new one.

The replacement they used MIGHT not have even been NEW - it might have been salvaged from another vehicle... or they might have used the wrong one for your Terracan. How much do you trust that shop? You might have the Terracan towed to a different shop if you're not pretty confident about their competence.

What is the next step in diagnosing our Terracans electrical problem

code p1123 refers to long term fuel trim--additive--mixture too rich===causes-- HO2S--fuel pressure --fuel system---mechanical fault---ECM
check all wires and connections. With the mechanical fault I would be revisiting all the items you removed to get to the rocker cover to ensure that all the hoses and wires were correctly replaced and that the gasket has not been mis -fitted or squashed out from under the cover at some point

Car sometimes wont start unless you spray starter fluid, just replaced filter. oem codes are p0734 and p1401

P0734 = 4th gear incorrect ratio (that's the torque converter 'lock-up' clutch - inside the converter).
P1401 = doesn't exist for 2002 Hyundai Accent's
P1401 exists for 2000 Accent = DM-TL Air Pump Motor Curent Draw is higher or lower than expected (normal is 17-36 mA). DM-TL = Diagnostic Module for Tank Leakage & is part of the Evaporative Emissions Control System.

These two DTC's are not associated/part of the Accent's Engine Managemenet System (EMS).
Best to have a qualified/certified Hyundai Service Technician properly diagnose this starting problem with your vehicle.

Sounds like a Brake Lamp Switch malfunction. Have a qualified Hyundai Service Technician properly diagnose your vehicle. Sonata's are notorious for this.

Speedo stopped working trans started to shift hard does not turn off door locks lock you in dattery dies alternatoe tests were good all symtoms appeared within days of each other

You have described several systems which can produce the symptoms you're having. First thought regarding the speedo and hard shift - VSS - Vehicle Speed Sensor is located on the transmission at the diffferential housing. OR, you might have an INPUT SHAFT and/or OUTPUT SHAFT speed sensor(s) malfunction. Best advice, take the vehicle to an authorized Hyundai Service Department to have it PROPERLY diagnosed - will most likely save you money in the long run. Have them scan the ECU/TCM (Engine Control Unit/Transmission Control Unit) for any trouble codes (DTC's = Diagnostic Trouble Codes). This will point the technician in the right direction (if there are any codes).

My temperature gauge rises moderately fast and goes into the red when i turn the the air conditioning or the heated rear window switches on

Help me out here.... which Hyundai vehicle are we discussing (it would be a great help). However, you describe an issue I've seen with electrical systems on Hyundai cars. You may have an electrical issue dealing with wiring 'ground' connections and/or the main power cable between the alternator and battery. Have a qualified Hyundai Service Technician properly diagnose
your vehicle. OR you can Go to and register your vehicle by VIN #..
you'll then have access to wiring diagrams, shop manuals, service bulletins, illustrations, etc.
