Hi bike lovers! Today we talk about a part on your Harley. It’s small, but super important. It’s the crank position sensor. It tells your bike’s computer how fast your engine spins. When it goes bad, your bike feels sad. Let’s learn some signs to look out for!
What is a Crank Position Sensor?
A crank position sensor (CPS) is a clever little part of your Harley. It lives near the engine’s crankshaft. The CPS is like a secret code reader. It reads marks on the crankshaft as it turns. Then, it tells your motorcycle’s computer this info.
This helps your Harley decide when to spark and squirt fuel. With a happy CPS, your bike starts and runs smoothly.
Top Symptoms of a Failing CPS
| Symptom | What it means |
|---|---|
| Hard to Start | If your bike is grumpy when starting, CPS might be the reason. |
| Stalling | Your Harley might say “nap time” and stall if the CPS is tired. |
| Jerking or Misfiring | Does your ride act like a bucking bronco? The CPS could be bad. |
| Check Engine Light | A scared engine light might pop on if the CPS sends confusing signals. |
| Poor Fuel Economy | If your Harley gulps more fuel, the CPS might not be chatting right. |
Breaking Down the Symptoms
- Hard Starting: Your Harley might not want to wake up with a weak CPS. It could take more tries to start.
- Stalling: A bike that stalls might have a CPS that’s lost its groove.
- Jerking or Misfires: Sudden jerks or misfires can happen if the CPS is sending wrong timing info.
- Check Engine Light: When the computer gets confused by the CPS, the check engine light might shine.
- Fuel Economy: If the CPS tells lies, the bike uses extra fuel to try to fix it.
Remember, these symptoms could also mean other parts have problems. Always check everything!
Why does a CPS Fail?
Here are a few reasons your CPS might stop being your bike’s best friend:
- Heat: Harley engines get hot! The CPS might get tired from the heat.
- Wear and Tear: As you ride, the CPS grows old, like your favorite jeans.
- Damage: Sometimes, things bump and bruise the CPS.
- Wiring Issues: The wires to and from the CPS can get cranky and cause trouble.

Fixing a Bad CPS
If you think your CPS is throwing a tantrum, here’s what to do:
- Check the Basics: Make sure the battery is charged and connections are clean.
- Scan for Trouble Codes: A special tool can read what the bike’s computer thinks is wrong.
- Visual Inspection: Look at the CPS. Does it look sad? Check for damage or dirt.
- Testing: You might need a pro to test the CPS with cool tools.
- Replace if Needed: Sometimes, you just need a new CPS to make everything good again.

Caring for Your CPS
To keep your crank position sensor happy, remember a few tips:
- Keep your bike clean. Dirt can make the CPS grumpy.
- Watch out for heat. Too much hot air can wear the CPS down fast.
- Regular check-ups. Sometimes, your mechanic can spot a CPS problem early.
