Crankshaft Position Sensor Buying Guide — Cheap OEM Replacement Parts for Sale | REVXSC
Looking for cheap crankshaft position sensors that won't fail in 6 months? Whether you're chasing ford explorer 5.0 crankshaft position sensor replacement, p0335 crankshaft position sensor fix, no start crank no spark crankshaft sensor, where is crankshaft position sensor located, crankshaft sensor symptoms intermittent, this guide covers what to buy, what to skip, and how to make sure the part you order actually fits your truck or car. Every crankshaft position sensor sold at REVXSC ships with a verified year/make/model/engine fitment table — no guessing.
What crankshaft position sensors actually do
In one sentence: the sensor that monitors crankshaft rotation and position so the ECM can fire spark and inject fuel at exactly the right moment. When they wear out, you'll typically feel it before you see it — your car starts telling you something is wrong, and ignoring it gets expensive.
Signs you need new crankshaft position sensors
- engine cranks but won't start
- intermittent stalling at highway speed
- rough idle and misfires
- tachometer drops to zero while driving
- check engine light with P0335 or P0336 codes
If you tick more than one box, replace before it leaves you on the side of the road. The repair gets a lot cheaper when you catch it early.
Also known as
Depending on the shop manual, region, or supplier you're reading, crankshaft position sensors are also called: CKP sensor, crank sensor, crank position sensor, crankshaft sensor, engine position sensor. They all refer to the same component — when you're cross-referencing OEM and aftermarket part numbers, watch for these naming variations so you don't double-order the same item.

OEM vs aftermarket: which to choose
For crankshaft position sensors, the brand actually matters. Bosch and Standard Motor Products supply major automakers as OEM suppliers — when you buy their boxed retail product, you're getting the same engineering and tolerances. Choose between magnetic two-wire passive sensors for older engines, Hall-effect three-wire sensors for modern applications, or upgraded heat-resistant sensors from Standard Motor Products and Bosch for engines that fail prematurely from heat soak..
Install: DIY or shop?
Difficulty: intermediate. Bay time runs about 30–90 minutes with the right tools. Lifespan you should expect: 80,000-150,000 miles.
How REVXSC keeps prices low

Common questions Americans ask about crankshaft position sensors
What are the symptoms of a bad crankshaft position sensor?
Common symptoms include engine cranking but not starting, intermittent stalling while driving, rough idle, misfires, tachometer dropping to zero, and check engine light with codes P0335, P0336, P0337, or P0338.
How much does a crankshaft position sensor cost?
Quality replacement sensors run $30 to $90 from Bosch, SMP, or ACDelco. OEM units from a dealer cost $80 to $250. Shop labor is typically 30 to 90 minutes, adding $50 to $200 to the job.
Can I drive with a bad crankshaft position sensor?
A failing sensor can leave you stranded with no warning because the engine can't run without crank position data. If you suspect a failing sensor, replace it before it strands you. Intermittent stalling is the most common warning.
How do I test a crankshaft position sensor?
Use a multimeter to check resistance against spec on two-wire passive sensors. For three-wire Hall-effect sensors, key-on voltage should read 5 volts on the signal wire. An oscilloscope is the gold standard for confirming a clean square wave during cranking.
Where is the crankshaft position sensor located?
The sensor typically mounts on the engine block or timing cover, aimed at a reluctor wheel on the crankshaft. Common locations include behind the harmonic balancer, on the bell housing flange, or under the starter motor. Service manual confirms exact location.
How long do crankshaft position sensors last?
Quality crankshaft sensors typically last 80,000 to 150,000 miles. Heat soak from engines that run hot, oil leaks that contaminate the sensor, or vibration damage from a worn harmonic balancer can shorten lifespan significantly.
Will a P0335 code clear itself?
Rarely. P0335 indicates the PCM is not receiving a clean signal from the crank sensor. The code may go pending if the issue is intermittent, but a stored code usually requires sensor replacement or wiring repair to clear permanently.
Do I need to program a new crankshaft sensor?
Most vehicles do not require programming, but many modern Fords, GMs, and Chryslers need a crankshaft variation relearn procedure with a scan tool after sensor replacement. Skipping this can cause misfire codes.
What causes a crankshaft position sensor to fail?
Common causes include heat damage from underhood temperatures, oil contamination from leaks, vibration from a damaged harmonic balancer, electrical surges, and simple age-related coil or Hall-effect failure inside the sensor body.
