However, an oxygen sensor is easy to replace on many cars and is usually detailed in the owner's manual. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one. Regardless of how you approach it, you should get this fixed right away. So you should chech it on our car models. The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.

If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

Parts or components should not be replaced with reference to only a P DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.

The solution is here :.There are many systems in place to ensure that the engine in your vehicle will operate as designed. A smoothly running engine is often taken for granted until a problem comes to light and the operator is left to diagnose the problem. A misfire is often chalked up to ignition timing when, in fact, there are a number of reasons the engine could be running rough. If you find yourself in the unfortunate position of having a misfire in your Dodge Ram, understand that there are many reasons your vehicle might be acting up.

The first process that must be investigated when a misfire is detected is the ignition system. This consists of the timing, distributor, coil, spark plugs, plug wires and electrical components, including the charging system. As these components begin to fail, the initial misfire will be very slight and difficult to detect.

As the components deteriorate into a more advanced case of ill repair, the problem will become more noticeable. Left unattended, this can lead to complete failure, and the vehicle will cease to operate completely. Popping noises back through the intake manifold, severe surging and jerking accompanied by a rough idle and poor acceleration are all signs of an ignition problem.

Periodic inspection of the ignition system is recommended to prevent such ignition difficulty. Check the spark plug wires for damage and ensure that they are on the spark plugs tightly. If your vehicle is distributor equipped, you should also check the rotor for damage and wear. Check the timing itself with a timing light to ensure it is within specification. Another common reason and typically missed diagnosis for a rough running engine is the lean misfire. In this case, the engine is receiving too much air and not enough fuel.

This is most noticeable while the engine is resting at idle since this is when an engine typically requires more fuel to operate smoothly. The lean misfire condition is likely to disappear at highway speeds due to the more efficient flow into the combustion chambers. Some of the causes for a lean condition are EGR valves that are stuck in the open position, leaking intake manifold gaskets, faulty mass air flow sensors if your vehicle is so equipped and plugged fuel filters and bad fuel pumps.

Vacuum leaks are also the culprits for some lean conditions in an engine. A close inspection of your rubber vacuum tubing as well as periodic changes of your fuel filter and cleaning of your fuel injectors are invaluable in staying ahead of any fuel-related problems with your vehicle. Once again, it is much better and in most cases more cost-effective to be proactive as opposed to reactive in the maintenance department. Perhaps the most costly misfire malfunction to correct is the mechanical misfire.

Bad head gaskets, worn piston rings, bad valves and worn cylinder walls are all culprits. Damaged or broken rocker arms, broken valve springs, and worn camshaft lobes or lifters are also reasons for mechanical misfiring.

Most of these failures will be accompanied by some form of internal engine noise. A worn timing chain will often rattle as it slaps the timing cover, and a broken rocker arm will sound like a big piece of metal is rattling around inside the top of your engine. Other failures such as a broken valve spring may make no noise at all other than the engine popping and pinging. These mechanical failures are often heard as a more consistent noise and will in most cases increase in relative equality with vehicle engine speed.

There are cylinders in most vehicles. In order, each cylinder fires a spark plug in a smooth and steady manner. The crankshaft is then powered by energy that is released by the fuel. The cylinders control the revolutions per minute RPM of the crankshaft. All of the cylinders work together to ensure the continuous rotation of the crankshaft. If a cylinder misfires, the crankshaft revolutions per minute will increase or decrease. If the powertrain control module detects that there is an increase or decrease of the crankshaft revolutions per minute that is more than 2 percent, it will store the P trouble code.

The Check Engine Light will come on if the percentage of increase or decrease in crankshaft revolutions per minute is between 2 percent and 10 percent. The Check Engine Light will blink if the percentage of the increase or decrease in crankshaft revolutions per minute is more than 10 percent. A percentage increase or decrease in revolutions per minute greater than 10 percent indicates that the misfiring problem is more serious.

The P trouble code indicates that cylinder 1 is not getting the necessary spark resulting in a misfiring condition. Collects all trouble codes and freeze frame data stored by the powertrain control module, using an OBD-II scanner. After replacing these components, if the P trouble code returns, it may be necessary to inspect the fuel injectors and fuel injector wiring to see if they are in any way defective. Diagnoses and repairs any other codes that have been stored by the powertrain control module and are related to the P trouble code.

After the test drive, if the P trouble code returns, they will inspect the compression system of cylinder 1 this is rare. There could be an issue with the powertrain control module, if the P trouble code persists.

This is rare, but it may require replacing or reprogramming. Before replacing the spark plugs, spark plug wires, coil packs, and coil pack wires, complete a visual inspection of the fuel injector wiring for damage.

Although it is rare for faulty fuel injectors to be the problem, completing a quick visual inspection could save some time.

Because I had the same problem before an hour agobut the CEL gone and everything went so fineit only flashed for 4 seconds. The rough shaking and and idel only happens on startup. After that it run smooth and never misses at high speeds.

I just had the plugs and all the gaskets changed, as well as all fluids flushed and replaced, ran diagnostics With fixed module, and it the up a p code came up! I have the same problem!

Code P came up meaning Cylinder 1. I have a Impala. This my second time changing out that same spark plug. The first spark plug I bought had broke off in there. And my mechanic got it out and put another one in.
