Question about Cars & Trucks

Open Question

Well Pretty Much Simular to Some. I Put My Car On The Machine And It Read I Have A Pending CamShaft Position Sensor Which I Had That Changed Less Then 3months And Also PO300 PO302 PO304 and PO306 Misfiring Now I HadA Tune Up Which I Haven't Had Since I Bought The Car At 137 Thousand Plus Miles.So I Changed The Spark Plug Wires Head Surge And PVC Valve. Could It Have Anything Dealing With My Fuel Filter/Fuel Pumps Or Coils??????? Plus I Also Cleaned My Full Trottle Plate With Trottle Cleaner Which Was Still Attached 2 The Head Plate And Mabye Some Of It Could Have Got Inside The Head Plate Would This Also Be A Reason For My Car to Not Start!!??!???!!?!!

Sounds like you still have air leak.

Check all the tube connections associated with the inlet manifold. Also check the connections to the new PCV. The code is indicating a leak into the inlet manifold. If this serious you will notice a laboured idling of the engine. WIth the engine at idle, where you can, pinch close, one at a time between thumb and forefinger, the air/vacuum hoses making connection with the inlet manifold for about 20 seconds. You might not notice any change to the engine note until you again open the tube up. This process should allow you to locate a minor air ingress leak. Also use your ears and listen for any wheezing, sucking, or whistling sounds. Lastly try spraying joints etc with alcohol spray. When the leak is hit the alcohol when sucked in causes the engine to speed up.

If you get

error codes and
you have an engine that misfires or runs rough, it can be the injector for that
cylinder or the coil pack. The P0300 code is a random misfire code and may or
may not be the above. All the other messages are for misfire of a particular
cylinder indicated by the last digit.

Test the coil pack by switching it to another spark plug and
see if the problem follows to that cylinder.

If that makes no difference, it is very likely the injector.
Disconnect the injector connector of the same cylinder and measure the
resistance. It should be 13.5 to 14.2 ohms at 70 degrees temp. It can be up to
16 ohms if the engine is hot. If you see a really high resistance or an open or
short then you can try to change the injector. If not, you can remove the fuel
rail on that side and switch the injector to another cylinder and see if the
problem follows to that cylinder.

need a 22mm wrench to remove the fuel pressure regulator. The other connections
are std. When all screws are removed, GENTLY wiggle the rail up and guide it
smoothly out. Don't put any sideward stress on the injector bodies.

Here is how to identify cylinders

All of the
injector connectors have a Black with red stripe wire. The corresponding other
wire color on the injector connector that matches with above are

green......................Red/black stripe
stripe..........Red/white stripe

P0340 FORD - Camshaft Position Sensor Circuit Bank 1 Sensor 1Possible causes- Faulty Camshaft Position Sensor
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery
P0340 FORD Description The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.

When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Kia rio not starting

Timing belt should have been changed at 60,000 miles. A loose timing belt or teeth missing from synchronous belt will lose timing. Damage to valves can occur if timing is not correct.

The car is a 4cl 1993 no spark.changed coil and igniter

  • Test the Camshaft Sensor
  • Check voltage between the camshaft position sensor terminals. With engine running, voltage should be greater than 0.1 volt AC and vary with engine speed.

  • Check the Crankshaft Position Sensor.
  • Using an ohmmeter, measure the resistance between terminals. Resistance cold should read 1630-2740 ohms and hot; 2060-3225 ohms.


  • Could also be a timing belt issue.

  • Make sure the distributor is spinning (rotor)

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

No, actually I would find a different Mechanic. 2000 and newer the TPS, Throttle Position Sensor, is pretty much standard to control idle RPM. Even in Fuel injection, it is just located on an Air control valve instead of a Carburetor.

P0340 is for camshaft position sensor circuit malfunction so the problem can be in you hav already changed sensor, then you need to check wiring from sensor to ecu and if the wires are ok than check the ecu! It can be either of them cousing the problem.

Changed the timing belt and camshaft sensor on a 2005 pt crusier pretty sure its timed correctly because the car seems to run fine and revs high with no problems although it still throws P0016 code even...

What the P0016 code means. P0016 is the OBD-II generic code indicating that the camshaft position sensor for bank 1 does not correlate to the signal from the crankshaft position sensor. The camshaft timing is out of position due to the timing chain jumped teeth. The camshaft phaser is out of position due to problems with phaser.
