The codes are specifically listed as P and P codes. The description in the Service Manual is: P P0151 harley 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 with the IED's in place, p0151 harley.

Get about five miles down the road come to a stop sign and the bike sputters and dies. Put it in neutral and restart. It's running a little rough and is low on gas so, I drive the 5 miles down the road to the gas station.

Bike fires up and I drive the rest of the 50 Miles to work. Lower voltage equates to a leaner fuel mixture in the eyes of the ECM. There are p0151 harley other reasons that the ECM will trigger the codes that we will try to cover below, p0151 harley.

Harley diagnostic trouble codes make identifying a particular problem in your motorcycle easier. Therefore, hundreds of these fault codes exist, indicating problems with the carburetor, engine, battery, sensors, and fuel injector. But what is the Harley code P? The code displayed due to a faulty rear oxygen sensor. Typically, this code will appear when the engine control module detects low voltage for the bank 2 sensor 1. This could be due to an exhaust leak or a shorted O2 sensor circuit. So then, how do you diagnose the Harley P code and fix it? This is a diagnostic trouble code that pops up when the ECM detects a low voltage at the rear oxygen O2 sensor. The low voltage issue is due to excess oxygen in the exhaust. However, this code is related to the bank 2 sensor 1 and not the Bank 1 sensor 1, which usually triggers Harley code p

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 with the IED's in place. The O2 sensor produces a 0. Lower voltage equates to a leaner fuel mixture in the eyes of the ECM. 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. The IED's take advantage of this voltage shift to richen the mixture. So the engine can be running rich and the ECM might still trigger the "sensor low" signal.

Check codes when I get to the office. From what I understand the bike is in closed loop most of the time. For any active check engine light, you want to have that checked to find out what is setting off the CE light. Wooden Rat Replies. In normal conditions, the O2 sensor produces mV in a Active error codes will cause the Check Engine light to come on. Find all posts by jjdaly. View Public Profile. Find all posts by Jackie Paper.

Recommended Communities. I have always been willing to swap out or refund returned IED's for riders that feel there is a problem with them. Since the day I bought it I've had problems with it running too lean pinging etc Thanks for the insight guys. I knew better than something wasn't right. A few intrepid souls have gone through their exhaust systems multiple times before the codes go away. Same code and same tuner. Think I'll go ahead and replace that and see if it helps. I had the same thing happening until I did this on my new to me '08 Road King this Spring. The O2 sensor produces a 0. First find out if they are functioning or bypassed, that may be the reason for the 02 codes you are getting. Prayer Requests. Wooden Rat Replies.
