We recommend Torque Pro. When a code PB is stored, you may assume that the powertrain control module PCM has detected an input signal from the circuit of the diesel particulate filter DPF pressure sensor indicating that differential pressure is too high. This code is used exclusively in diesel powered vehicles. DPF systems are used to clean up exhaust emissions in diesel powered vehicles. They remove up to ninety-percent of carbon soot from the exhaust. Diesel engines produce black smoke from the exhaust, especially under acceleration.
Soot is the main ingredient of the smoke. The DPF filtration element is secured in a steel housing. It resembles a fat muffler or catalytic converter. Ceramic based cordierite wall fibers are some of the most common elemental compounds that are currently being used in DPF composition. Cordierite is known for its excellent filtration characteristics. It is also known for a tendency to overheat at extreme temperatures, making it susceptible to malfunctions in vehicles equipped with passively rejuvenated DPF systems see the paragraph below on DPF regeneration systems.Cisco cli python library
The heart of the DPF is the filtration element. When an excessive accumulation of soot particles takes place inside the DPF, exhaust pressure increases. When exhaust pressure exceeds a predetermined limit, as indicated to the PCM by the DPF pressure sensor, the filtration element must be regenerated.
Proper regeneration of the DPF permits exhaust gases to continue flowing through the DPF so that the correct level of exhaust pressure can be maintained. In this case, the PCM is programmed to inject chemicals including but not limited to diesel fuel and diesel exhaust fluid into the exhaust at programmed intervals when DPF pressure reaches a certain level.Cervello geniale in english
Under the correct driving conditions, an electronically controlled injection causes the temperature inside the DPF to increase. This temperature increase causes trapped soot particles to burn and be released through the muffler and tailpipe as ions of nitrogen and oxygen.
Passive DPF regeneration systems are very similar to active DPF regeneration systems but they typically require some type of manual input. Passive regeneration systems are normally activated when the vehicle is parked and the process may take several hours to accomplish once it is begun.
Once the DPF filtration element is sufficiently regenerated, pressure inside the DPF should drop to an acceptable level. If the PCM detects a DPF pressure condition that is higher than programmed parameters, a code PB will be stored and a malfunction indicator lamp may be illuminated. Make sure that the vehicle has an adequate amount of the correct reductant fluid or diesel fuel for DPF regeneration purposes.
Codes of this type are often the result of the vehicle being out of reductant fluid or having the wrong type of replacement fluid.
Some driving habits may also contribute to inefficient DPF regeneration that can cause this type of code to be stored. Many passive and active DPF regeneration systems demand to be driven under heavy loads or at a minimum level of continuous acceleration over a set period of time, before regeneration can be completed. My diagnosis typically begins with a visual inspection of system harnesses and connectors. I would proceed by connecting the scanner to the vehicle diagnostic connector and retrieving all stored codes and freeze frame data.When you check engine light came on code PB the reason should be.
So you should chech it on our car models. When the check engine light comes PB code on the first you should check is the gas cap. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. Continue driving and see if the check engine light turns off. All you need to do is take the old one off and screw on the new one. If you've already made it to the store, you might as well just replace it. While not car-threatening, it's good to take care of this right away to improve gas mileage.
The oxygen 02 sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions. PB DTC specifically refers to the camshaft cam timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. Engine trouble codes resource center for all car models.

P is an OBD-II code for the engine control module ECM detecting no exhaust pulse while monitoring the exhaust pressure sensor when the bank 1 switching valve is commanded to be open with the engine running. This will signal a fault in the system. The engine control module ECM monitors the exhaust pressure sensors to determine if the air injection system for bank 1 is operating correctly when it commands the switching valve open and closed.
The code is set when the air injection system switching valve for bank 1 is commanded open and the sensor is detecting no exhaust pulse indicating the valve is stuck closed or the pressure sensor is defective. The vehicle will not run any different in most cases, but you may have an exhaust leak at the switching valve. Scans for codes and documents the code in the ECM, and then looks at the freeze frame data for the problem.
Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired.
Code P is an indication that the air injection system switching valve is not working or a sensor problem that will cause no drive symptoms. The exhaust emissions will be affected and will cause the vehicle to fail emission testing. There may also be exhaust leaks that would cause the code to be present. Replacing the air control valve for the secondary air injection system bank one. Code P is for the secondary air injection switching valve being stuck closed for bank one of the engine with the exhaust possibly melting the valve causing it to stick closed.
Make sure you correct any engine lean condition or exhaust leaks in the manifold that could cause the exhaust to become hotter than normal. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.

An intermittent DTC P may be set. If P is the only DTC setting, there is a new calibration that has been released to address the high soot mass accumulation condition. The new calibration will address DTC P when associated with short trips and city driving. It also will repair the Tech 2 service regeneration operation.
Any other driveability symptoms or DTCs must be diagnosed and repaired. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. The monitor compares the calculated restriction of the DPF to two thresholds. By exceeding the first threshold for a sufficient period of time, a wrench light will be illuminated.
By exceeding the second threshold for a sufficient period of time, a wrench light and a MIL will be illuminated and engine output will be limited and EGR is disabled. Get Access to Factory Service Manuals. Need more help?

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.
