The codes are specifically listed as P and P codes. The description in the Service Manual is: P Front O2 sensor low or engine running lean P Rear O2 sensor low or engine running lean The key point to look at here is "O2 sensor low" when analyzing what is happening p0151 harley the IED's in place. The O2 sensor produces a 0, p0151 harley. Lower voltage equates to a leaner fuel mixture in the eyes of the ECM, p0151 harley.

Welcome, fellow car enthusiasts! Today, we explore a common trouble code in automotive diagnostics that can be puzzling: P We also cover its causes, severity, potential solutions, and estimated breakdown of repair costs. The P code indicates that the oxygen sensor Bank 2, Sensor 2 detects a voltage lower than the specified range. This sensor is typically located before the catalytic converter on the side of the engine with cylinder bank 2. It sends voltage signals to the engine control module ECM , providing feedback on the oxygen content. Based on this information, the ECM adjusts the fuel mixture to achieve optimal combustion and ensures the proper functioning of the emission control system.

Thanks in advance. Happy riding. Recommended Communities. CKP was the issue. As long as you do not get an active check engine light, you can run your bike with the IED's. Can I just run my bike with the codes and not worry? In some circumstances, the ECM will see this low voltage as "too low" and trigger the code despite the fact that the engine is running rich enough. You should upgrade or use an alternative browser. This graph shows how voltage output changes with temperature. We have found that many of the bikes that have codes will get rid of them when they carefully check their exhaust system. Some piggyback units like the cobra eliminate the 02 sensors and others keep them in line. I had to unplug them, plug the processor in Received 4, Likes on 3, Posts. Unless you check the historical codes on your bike, you might never see these. First find out if they are functioning or bypassed, that may be the reason for the 02 codes you are getting.
