Recently the engine light on my 06 RK (FLHPI) has been going on and off occasionally. I learned how to check the codes tonight and came up with P0118 - ET Sensor Voltage Open/High EFI and then gave me p/n 34309-06.

I bought the bike in March from the local HD dealer with 7300mi on the clock. I recently hit 10,000mi including a 700mi trip from PA to NY and back (when I started noticing the engine light).

Can someone direct me as to what this code might mean? What might need fixed or replaced? I can do the work so I'd rather not take it to a dealer, I just need some direction as to what it might be.

Oh, and it's 1:30am here so if you need more info from me I'll be back in the morning. Thanks to anyone that can help me, hopefully I'm not asking a stupid question. I've searched the forum and all I could find was the code name above.

 

You can do a search using PO118 and you will find other posts which may be helpful. You can also find a lot of information in HD's Electrical Diagnostic Manual (EDM) for your model year (and probably other model years since the Diagnostic Trouble Codes don't change much from year to year); ask your HD service dept. for a look at their copy of the EDM if you don't have access to a copy.

Thanks for your suggestions. I checked with a buddy and he said the code means there's an issue with the engine temperature sensor on the front head. Sure enough, I looked between the tank and front head and the sensor plug had worked itself loose and was completely unplugged. Luckily an easy fix this time.

 

Lititz Pa me too are you the guy I gave some exhaust shields too.
