P015b

What has been done so far: Vehicle originally came in with PB. Told shop to repair exhaust leaks on 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. 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. They are mentioned below as follows:.

The PB error code can be defined as oxygen sensor response — lean p015b rich bank 1 sensor 1. I had already done some work calculating MAF, and it was far off. P015b, it is advised to replace them as soon as possible.

PB is a generic trouble code, which means it has the same meaning any vehicle. In the case of the Chevy Silverado, 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.

That goes for head to manifold bolts…. 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. I stated in the post, that the O2 sensors had NOT been changed. That goes back a number of years, and the vehicle affected like that, was a J body. Featured Products. The driver is fairly aggressive behind the wheel. I had this issue a couple of years ago on a Silverado and it turned out to be a poor ground at the negative battery cable where it attaches near the right side of the radiator. This has been an ongoing issue for over a month. I usually see the pulsewidth…. Code returned! Mark, There are always vehicles that it won't work on, Hydro-boost power brake equipped trucks for example. New MAF took care of most of those trims at an idle, but they're still annoyingly negative above that, about or so. A car engine which would not run properly would cause all sorts of codes to be stored.

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.

Similar to the composition issues that GM has had for a long time, on the flex vehicles, but only certain ones…and the fix has been varied. After thousands of successful repairs the listings of TSB are compiled. And, the issue has not been a problem for years. A major improvement from the s. Then you have arrived at the correct place. I see, the engine identification in the vehicle description lead me to think it was an LC9. I'll know…. We have best Exhaust Gas related parts with us. Investigating trim is always fun. Catalytic Converter - Catalytic Converter is an important car part which should never be neglected. Alcohol has less energy by volume than gas therefore a richer mixture is needed. I thought by now they had corrected the problem, knowing GM, probably not. Apparently the programming is in the PCM and somehow it gets screwed up even though it's not supposed to be enabled. The customer could get the code to set in about 10 miles and I couldn't get it to set in 30 miles, even if I drove the same 15 miles he drove to work. So, it is advised to replace them as soon as possible.
