What was the code for my GM Truck?

Limped home at 30 we had 0300 174, and a host of other codes. I just cleaned the intake upper and lower, and installed the good felpro set. After the install we found slightly low comp on two cyl so pulled the heads sent them in for a rebuild this fixed the comp probem.

What does a misfire code on a check engine light mean?

Misfires that turn on the check engine light and log a cylinder-specific fault code are the easiest to diagnose. The OBD II system will identify the cylinder (s) that are not contributing their normal dose of power and set a code that corresponds to the firing order. A P0303 code, for example, would tell you that the No. 3 cylinder is misfiring.

What causes a failure code on a Ford?

Some Fords have a removable tube. Another common problem causing failure codes in this system is that the tip of the valve will become irregular shaped from carbon deposits. When this happens it no longer creates a perfect seal. This can allow exhaust gas to continue to flow when not called for by the computer.

Which is the second most common cause of an engine misfire?

The second most common cause of a misfire is bad spark plugs. The spark plugs fire up up your cylinders, and they can get worn over time. Spark plugs are often very cheap and in most cases easy to replace. If you can’t remember the last time you replaced your spark plugs, it’s probably time to replace them.

When do I get a misfire code on my engine?

Misfire codes do not always indicate there is an issue with the ignition system. A misfire code is set when the computer detects a situation where there is an unexpected change in crankshaft speed. With most engines, the crank sensor is the key component in determining a misfire.

Can a bad ignition coil cause an engine to misfire?

Of course, because all cars are different, an ineffective ignition coil may register a different code for the problem. Alternatively, you may see a code for an engine misfire, which could be the result of a dead ignition coil. If an ignition coil is not working properly, your engine will likely misfire.

What causes an engine to misfire on all cylinders?

Low fuel pressure will cause a lean mixture in your engine which will result in misfires on all cylinders. If you have trouble codes for misfires on all cylinders, you will want to check your fuel pressure. 5. Injector Problem Another problem, which was more common five years ago, is injector problems.

How to check the status of catalyst monitor?

So, in order to make the status of catalyst monitor ‘ready’, you need to follow these simple steps. 1. Make Sure the Engine Light is Off The first and foremost step is to check whether the engine light is off. If your vehicle has active trouble codes, it may stop a monitor from running completely. 2. Check if your Vehicle has a Coolant Temperature

Why does the Check Engine light not come on when a catalytic converter fails?

A healthy converter will use a lot of oxygen, and so the rear oxygen sensor will see that there is little oxygen coming out of the back of the converter. In this situation, the “check engine” light will not come on to indicate catalytic converter failure, because all is well.

How much does it cost to replace a catalytic converter?

So your car or truck is running well, but that check engine light is on, with a code P0420 or P0430, and related catalyst efficiency below threshold codes. You like your car, so you take it to be looked at. You choke on the estimate of $1400 or more to replace the converter on your car.

What does it mean when your car says p0430?

Code P0430 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.
