P015b

What has been done so far: Vehicle originally came in with PB, p015b.

If your car mechanic has told you that there are some defects in the oxygen sensor, catalytic converter or there is some leakage in the car engine exhaust, then you should not keep calm because PB fault code is soon going to trigger. The PB error code can be defined as oxygen sensor response — lean to rich bank 1 sensor 1. Are you searching for some more information about PB fault code? Then you have arrived at the correct place. It is the oxygen sensor which measures the content of oxygen in the exhaust gases once the combustion process of the engine has been left.

Told shop to repair exhaust leaks on exhaust. That goes for head to manifold bolts…, p015b.

PB is a generic trouble code, which means it has the same meaning any vehicle. In the case of the Nissan Versa, It indicates that the Oxygen O2 sensor on bank 1 is not cycling from lean to rich as fast as it should be. The powertrain control module PCM uses this data to optimize the air-fuel ratio. The oxygen sensor sends data to the PCM as a voltage value. O2 sensors are notorious for having wiring harness issues, this is due to their proximity to the exhaust system. The hot pipes can make the wiring brittle. When diagnosing PB, there can be two scenarios. The first is that the oxygen sensor is bad, either due to an internal issue or a wiring problem. Exhaust issues are the way scenario two happens. This increase in exhaust pressure can lead to a delayed change in recorded values from the oxygen sensor, which will be recorded as PB.

Does anyone know where this particular O2 sensor is located? I'd like to check to see if it's plugged in if possible. The car is a This may be a red herring but the car came out of the body shop last week for a right front fender replacement due to damage by snow clearing equipment. During the repair they removed or disconnected the right front headlight assembly I got an Onstar notification.

Well, another pair of junk AM O2 sensors were the culprit. Oscar Mechanic. If the one is found which would match the symptoms as well as codes presented by the vehicle in question, then it would very likely aid you in your diagnosis. The engine is running too rich and the o2 sensors are overwhelmed look for possible valve train sloppiness this drives up the numbers. The 5. They next swapped out the injectors on Bank 1, code returned. Some vacuum pump vehicles won't work either, some use vacuum pumps as an auxiliary vacuum source and those vehicles will still work. Mostly MAFs and fuel pressure issues. Powertrain Control Module - Do you remember when was the last time you got your car Powertrain Control Module checked up? And, I agree that Chrysler is probably using it to prevent….

I see, the engine identification in the vehicle description lead me to think it was an LC9. But, there isn't a lot of testing support for the composition issues…except a software fix. Rear trim isn't necessarily a change in pulse-width at all, but…. I had the customer drive the route and sure enough after 10 miles the mil…. Catalytic Converter - Catalytic Converter is an important car part which should never be neglected. Took longer for the code to reset, but reset it did. If any failure is detected by the powertrain control module of the sensor or the information is received from the sensor, then it would result in the triggering of the PB fault code. There are exceptions to the rules ,as always. MIL On. After thousands of successful repairs the listings of TSB are compiled. Some vehicle will have an alcohol content sensor, other will use an after refueling strategy using 02 sensors to…. A car engine which would not run properly would cause all sorts of codes to be stored. Or, maybe it's just the way the signals are processed internally…. In some Silverados came with direct injection but no Suburbans did until
