What happens when a crank sensor goes bad?
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 causes a crankshaft position sensor to fail?
There are a few things that can cause the crankshaft position sensor to fail, including damage, debris and faulty circuitry. Even for modern electronics, the engine is a violent and destructive environment. Though built for this, most sensors eventually succumb to the ever-present heat and vibrations of the engine.
Will a bad crankshaft position sensor throw a code?
A failing or failed crankshaft position sensor may cause the check engine light on your dashboard to come on. A diagnostic scan tool will show a code between P0335 and P0338.

How much does it cost to replace a crankshaft position sensor?
Crankshaft Position Sensor Replacement Cost. The average cost to replace a crankshaft sensor ranges between $150 and $250 . However, it’s not uncommon for those prices to skyrocket if you have a higher-end vehicle. That’s because the labor costs are typically between $90 and $110. From there, the rest of the cost comes down to parts.
What is the function of a crankshaft position sensor?
It informs the Electronic Control Unit (ECU) of the exact position of the Crankshaft.
