P015b

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

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.

Took longer p015b the code to reset, but reset it did, p015b. I thought by now they had corrected the problem, knowing GM, probably not.

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

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.

You probably have come across GMs with a similar issue except that they…. Learn the ways with which you can correct this trouble code:. Common Symptoms. 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. They found several leaks on the driver's side, and allegedly repaired them, using the shopvac approach. She works at the shop and is cognizant of which fuel is which. So, it is advised to replace them as soon as possible. Took longer for the code to reset, but reset it did. I guess it does not apply then. Apparently the programming is in the PCM and somehow it gets screwed up even though it's not supposed to be enabled.

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.

They replaced it with OEM, and the trims, while not great, are acceptable. There is no need to get strained if your OBD Code is still flashing up as we are here at your service. 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. Told shop to repair exhaust leaks on exhaust. The technical service bulletins or the TSB should be searched in your vehicle information. Defects in the O2 sensor The wiring or connectors may be burnt, broken, or sometimes may get disconnected Some faults with the catalytic converter Leakage in the car engine exhaust. Far better, but the issue is not solved. I told them to swap O2 sensors side to side. I've been resetting composition for years, Ain't my first rodeo. That goes back a number of years, and the vehicle affected like that, was a J body.
