Check wiring connections between ECU and TPS (Throttle Position Sensor). Chances are your TPS has malfunctioned. The ECU (Engine Control Unit) monitors TPS signals at regular intervals. I trust your computer (ECU) to have done it's job... Replace the TPS
Go to www.hmaservice.com and register your vehicle by VIN #..
you'll then have access to wiring diagrams, shop manuals,
service bulletins, illustrations, etc.

Crankshaft position sensor


Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition, the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms No Start / Intermittent Start Condition - Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit.
NOTE: For procedures on the position sensors, please refer to Driveability and Emissions.
Removal & Installation To Remove:
  1. Before servicing the vehicle refer to the precautions at the beginning of this section
  2. Raise and support the vehicle
  3. Remove or disconnect the following:
    • Air deflector
    • Oil filter adaptor gm_car_cad_sev_ckp_rem.gif

    • CKP sensor electrical connector
    • CKP sensor retaining bolt
    • CKP sensor
To Install:
  1. Lubricate the CKP sensor O-Ring with clean engine oil
  2. Install or connect the following:
    • CKP sensor and the retaining bolt
      1. Torque to: 89 lb-in. (10 Nm)
    • CKP sensor electrical connector
    • Oil filter adaptor
    • Air deflector
  3. Lower the vehicle to the ground.
  4. Operate the engine then inspect the CKP sensor for engine oil leaks.
  5. Perform the CKP System Variation Learn Procedure.
  6. Test drive the vehicle.

1998 elantra was running fine and motor just died. Will turn over fine but will not start. I had filled up with fuel and driven about 50 miles when this happened.


Is the engine getting fuel and spark?

Try to put a few teaspoons of gas in the throttle body to see if it starts up. If it doesn't then the engine's spark plugs may not getting spark.

A possible coil may be the root of the above problem.

If it does start and run for a few seconds then the spark is good, but the fuel pump may not be pressurizing (bad fuel pump) or the fuel injectors are not firing (possible PCM or Powertrain Control Module).

A crankshaft position sensor can also cause a no start condition.
It is located near the Crankshaft of the engine.

Here's more information about the crankshaft position sensor which if bad, can cause a no start or no run condition.
Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition, the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms No Start / Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit. (See also Engine Mechanical)

These are just a few possibilities, and if one takes it to the dealer to have the engine diagnosed, that might be a good place to continue of the above doesn't isolate the problem sufficiently for repair of the no start condition.

Where is the cam sensor on a 2005 dodge neon sxt 2.0


Camshaft Position Sensor-On top of engine Operation The Engine Management System (EMS) uses the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The EMS constantly monitors the number of pulses on the signal circuit. The EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses, Diagnostic Trouble Codes (DTCs) should be stored in the EMS. Some engine management systems will then default to multi-port or "gang-fire" injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start. However, the EMS misfire diagnostic will likely be affected.
The following symptoms can be caused by an intermittent wiring connections or faulty signal to the EMS.
Related Symptoms
  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration

High idle stalls at lights code for crank sensor


Crankshaft and Camshaft Position Sensors Camshaft Position Sensor Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:
  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration
