I’ve got an 07 Softail Standard and I disconnected the O2 sensors, ran the bike a little, then hooked them back up. I was trying to get it to run cooler, which it did but it reduced HP as well and the check engine light was on all the time. Now that everything is hooked back up the enging light is still on. Anybody have any idea how to reset it? Thought about trying to disconnect the battery.

 

Even if you disconnect the battery the CEL may turn off, but the code will still be stored. I am sure if you buy a scan tool, you can reset the the fault code easy, and the light will go out. Its way too dangerous to ride around with the CEL on, because if you had a real problem, the ECU now has no way of letting you know about it.

 

How did you know if it was running cooler with them unpluged? Did it seem cooler or were you using a temp. gage?

 

It just felt a cooler, didn't use a temp gage.

 

Hold the speedo trip button in and turn on the ignition
This put you in diagnostic mode then use trip button
to cycle thru and i think you can clear codes this way also

Did this work?

 

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background lighting sould illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.
4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.
5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC’s the code will be displayed or the word "none" will appear if there are no DTC’s. Push the odometer reset button again to view additional codes if they exist.
7 - Record the codes.
8 - If DTC’s are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC’s again by repeating steps 1 to 9. If the code is current it will reappear.
9 – Press and release the odometer reset button to continue to the next module.
10 – Turn Ignition switch to OFF.
