What has been p015b so far: Vehicle originally came in with PB. Told shop to repair exhaust leaks on exhaust. They found several leaks on the driver's side, and allegedly repaired them, p015b the shopvac approach. Took longer for the code to reset, but reset it did, 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.

I had already done some work calculating MAF, p015b it was far off, p015b. Some vehicle will have an alcohol content sensor, other will use an after refueling strategy using 02 sensors to….

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.

They are mentioned below as follows:. Mark Engineer. They did that, and now we've got codes for BOTH banks? I've been bitten on a Dodge B-van, by a rear O2 sensor gone awry, that literally made the van run like crap…and that was ages ago, so the rears obviously have some input. Probably, as it seems to be a non-issue these days. But, we're still awaiting the OEM sensors. Caleb Diagnostician. The 5.

Investigating trim is always fun. There is no need to get strained if your OBD Code is still flashing up as we are here at your service. If I remember correctly it was an older vehicle, a or GM product. I did recommend new OEM sensors, and told them to learn them with their scanner. Are you searching for some more information about PB fault code? In some Silverados came with direct injection but no Suburbans did until You never know. They are mentioned below as follows: Common Symptoms Decrease in the overall fuel efficiency There can be lack of engine performance Other diagnostic trouble codes which are related to this code may also be stored Service engine soon lamp may can illuminate. Yes, the problem of negative trims is not actually when there is E85 in the tank but rather when the pcm THINKS there is alcohol content in the tank and there is not. Then make sure that there are absolutely no exhaust leaks on that side. Oscar Mechanic. Featured Products. Told shop to repair exhaust leaks on exhaust. The driver is fairly aggressive behind the wheel. The main focus should be on the harnesses that are routed near hot exhaust pipes and manifolds, as well as those that are routed near sharp edges like the ones found on exhaust shields.
