A failing crankshaft position sensor cannot provide the right information about piston positioning in the engine, causing a cylinder to misfire. This could also occur from faulty spark plug timing, but if the spark plug checks out, then the crankshaft sensor is likely the source.
What happens when a crankshaft goes bad?
Uneven Acceleration
This could be a sign of a failing crankshaft. If your crankshaft sensor is not working properly, the motor control unit in your vehicle won't be able to execute the changes to the fuel injection or to the spark timing whenever the engine speed climbs.
How do I know if my crankshaft is bad?
Signs of a bad crankshaft
- A forging or casting flaw.
- Insufficient lubrication.
- Bearing wear.
- Loose bearing main caps.
- Distorted bearing bores.
- Improper bearing clearance.
- Bearing failure.
Can a car run with a bad crankshaft?
If you wonder if it is safe to start your car when the crankshaft goes, the answer is yes if it is the very beginning of the issue. Once the position sensor becomes compromised or if you have symptoms of a problematic crankshaft that you can't ignore, do not drive your vehicle.
