It is usually necessary to remove the air filter assembly and other parts that may be obstructing the sensor to access the Harley Davidson crank position sensor location.
How to test a Harley Twin Cam crank sensor?
Testing the Crankshaft Position Sensor on a Harley-Davidson Twin Cam engine involves a few steps. Here’s a general guide, Harley crank position sensor test:
Tools Needed:
- Multimeter (Digital or Analog)
- OBD-II Scanner (Optional)
- Service Manual for your specific Harley model
Steps:
- Locate the Sensor: The crankshaft position sensor is typically located near the crankshaft, often on the engine block.
- Disconnect the Sensor: Carefully disconnect the electrical connector from the sensor.
- Set Multimeter: Set your multimeter to the ohms setting (Ω) for resistance testing.
- Measure Resistance: Place the multimeter probes on the sensor terminals. A good sensor should show a resistance of around 1k ohms. If it reads infinite resistance (open circuit), the sensor is likely faulty.
- Check Voltage: If you have an OBD-II scanner, you can check for voltage readings from the sensor while the engine is cranking. You should see a fluctuating voltage reading between 1-2 volts.
- Consult Service Manual: Refer to your Harley-Davidson service manual for specific resistance values and diagnostic codes for your model.
Diagnostic Codes:
- Code PO 374: Indicates a failed or faulty crank position sensor due to a synchronization error.
Can you drive with a bad crank angle sensor?
While it is possible to drive your vehicle with a bad Harley crank position sensor, it is not recommended. A bad sensor can cause a host of issues that can put your safety and the health of your vehicle at risk. Here are some of the reasons why driving a vehicle with Harley bad crank position sensor symptoms is risky:
- Engine Stalls: The engine may unexpectedly stall, which is especially dangerous while driving.
- Starting Issues: You may experience difficult starting or extended starting times.
- Decreased Performance: Engine power and acceleration may be noticeably reduced.
- Rough Idle: The engine may idle erratically or inconsistently, which may cause it to stall.
- Check Engine Light: An illuminated light indicates a problem that needs to be addressed, and ignoring it may cause further damage.
Driving a vehicle with a faulty sensor can damage the engine and other components over time. To ensure your vehicle runs smoothly and safely it is best to have the sensor checked and replaced as soon as possible.
