How to test the crankshaft position sensor on a Harley Davidson?
To test the crankshaft position sensor: Probe the connector wiring at the sensor. Small metal T-pins work great for this. Make sure the T-pins do not come into contact with each other. Clip or hold the multimeter probes to each T-pin. Set your meter to read AC milli-volts.
Is there a problem with the MAP sensor on a Harley?

What does the ho2s code p0031 mean?
P0031 is the code for HO2S Heater Control Circuit Low (Bank 1 Sensor 1) What the P0031 code means P0031 code means for the engine to run correctly, the engine exhaust must have a specific air-fuel ratio of 14.7 to 1 as signaled by the heated oxygen sensors (HO2S) which detect the oxygen content of the vehicle exhaust.
Where is the ignition sensor on a Harley Davidson Sportster?
The crankshaft position sensor location. The I.C.M. (ignition control module) was used on Sportsters before the year 2007. After 2007, the module became integrated into the E.C.M. (electronic control module). These modules contain internal circuitry found on most computer motherboards.

Code PO 374 indicates a failed or faulty crank position sensor due to a synchronization error. You cannot service crank position sensors, and you should replace them if faulty or damaged.
What kind of sensor is on the crankshaft?
Some cars employ two separate crank sensors—one that senses only TDC and another that measures the actual rotation. In this case, the first is usually called the crankshaft reference sensor, and the second may be called the crank angle or crank speed sensor. The other type of sensor is the Hall Effect sensor.
What should I do if my crank sensor is bad?
So if your car is a 1996 or newer model, the most common method of diagnosing a bad crank sensor is to plug in a code reader, read the fault code, and see if the crank sensor is listed as the culprit. However, if you have a pre-OBD-II car, you’ll have to diagnose it yourself.
