What does a crank position sensor on a Harley Davidson do?
A Harley-Davidson motorcycle engine may sputter and hesitate when a crank position sensor (CKP) starts to fail. The CKP sends data to the motorcycle computer data center about the position and speed of the crankshaft, the ignition and fuel injection.
Is there a crank position sensor on a FFI Electra Glide?
I have a 2003 FFI Electra Glide standard and it will not start. It cranks and cranks but no fire. I read the code on my bike with the Twin Scan tool on my computer. It told me that it was the crank position sensor.
Can a bad crank position sensor cause a check engine light to come on?
Sometimes the check engine light comes on after the crank position sensor is gone. But other times, it is fairly accurate. So whenever you see the light coupled with any of the problems mentioned earlier, it is probably the sensor. Driving with a bad crank position sensor is potentially dangerous.
What does po374 mean on a Harley Davidson?
If the sensor goes bad, the first thing it will show is a PO374 error code. This is a diagnostic trouble code for vehicles with an engine position sensor. For a Harley, the P0374 code may be shown when the powertrain control module (PCM) detects no pulses from the position sensor.

Do you have to replace the cam sensor on a Harley Davidson?
Correct. Which means the ECU would have to be replaced if eliminating the cam sensor, and using the crank sensor only. Now, in order to eliminate the sensor, you’d likely have to replace the ECU and the harness, as the plugs are likely different as well.
What should I look for in a Harley Davidson camshaft?
While there are no hard and fast rules for picking a cam for a specific application, some basic guidelines are worth considering. Keep in mind that performance camshafts are usually chosen for the basic purpose of producing more power from your engine. The three questions to answer before choosing a new cam for your Harley Davidson® motorcycle are:
Is the crank sensor connected to the cam sensor?
The later ECU is signaled by the crankshaft sensor only as far as I know. I was wondering if the crankshaft sensor on the earlier twincam could be wired to both ECU connections (to provide both cam and crank sensor signals) in order to eliminate the cam sensor.

What happens when the crank sensor on a Harley goes bad?
In newer models, the crank position sensor is designed in such a way that it allows you to reach your destination even after it goes bad. Usually, the symptoms of a bad crank position sensor on Harley Davidson are quite easy to notice. For example, you experience slight hesitation with the engine or reduced mileage, etc.
Why are twincam crankshafts used in Harley Davidsons?
We have remanufactured well over 10,000 TwinCam crankshafts – That is our sole testament to the value of our engineered Pro-Plug system. It provides integrity to the crankshaft as a whole to resist spreading of the wheels 180 degrees from TDC and does NOT allow the wheels to shift, something welding alone or ANY 5 piece crankshaft can not provide.

Why does my Harley Davidson cylinder misfire?
When your vehicle’s crank position sensor is failing, then you’ll notice the cylinder misfire. This is because it is unable to provide your vehicle’s computer with correct piston position information. When your Harley Davidson’s crank position sensor turns bad, you’ll notice the acceleration performing unevenly.
How does the CKP work on a Harley Davidson?
The CKP sends data to the motorcycle computer data center about the position and speed of the crankshaft, the ignition and fuel injection. A malfunctioning CKP can cause the engine to backfire due to unburned fuel and hesitate when accelerating.
How do you reset the odometer on a Harley Davidson?
Push and hold the odometer “Reset” button. Hold the “Reset” button and do not release it yet. Turn the key to “Ignition,” but don’t start the engine. Release the odometer “Reset” button.
Is there a crank sensor on a Harley Davidson?
The backfiring you describe doesn’t sound like a crank sensor. Usually when bad, the bike wont accelerate, dies spits and pops, dies won’t run hardly at all if off idle. By the way, some times, some digital meters are funny trying to measure magnetic sensors.

What causes a Harley Davidson crank to run out of sync?
Slack in any chain has the capacity to align then dis align. Like the timing chain on a car. It runs good then it runs ruff. If you have worn cams or cam adjusters then the chain may take on an initial start and when the slack starts like when letting off the throttle it throws the timing out of SYNC. Hence Backfire.
