What does the Camshaft Position Sensor do?

A camshaft position sensor monitors the position and speed of the camshaft in an engine, feeding vital data to the engine control unit (ECU) for the right fuel injection and ignition timing. This helps the engine run smoothly and keeps emissions down.Where the crank sensor tracks engine speed, the cam sensor tells the ECU which cylinder is on its compression stroke, so the engine can inject fuel and fire each cylinder in the correct order and adjust variable valve timing. It usually sits at the top of the engine, near the cylinder head, reading a target on the end of the camshaft. Tucked up there among heat and oil, it wears with age, and a poor signal soon shows up as rough running.

What are the symptoms of a faulty Camshaft Position Sensor?

A failing cam sensor rarely stops the car dead the way a crank sensor can, but it makes for frustrating, unreliable running and a dashboard full of warnings. A car limping along on a failing camshaft position sensor can lurch or lose power unexpectedly, so it's worth sorting before it leaves you stranded or fails an emissions test. The usual signs:
  • A lit check engine light: Often the first clue, logging a cam-sensor or timing fault code.
  • Hard starting or long cranking: The ECU takes longer to work out engine timing without a clean signal.
  • A rough or lumpy idle: Mistimed injection makes the engine run unevenly at rest.
  • Hesitation or stumbling: Power flat-spots as the timing data drops in and out.
  • Going into limp mode: The ECU caps power to protect the engine when the signal fails.
  • Worse fuel economy: Batch-firing instead of sequential injection burns more fuel.
A used or aftermarket camshaft sensor undercuts a dealer part by a wide margin, yet the listings are dotted across plenty of separate sites. Parthunt24 pools used camshaft position sensor listings from marketplaces like Ovoko, ProxyParts, eBay, and TotalParts, lining up 207 options to judge on price, condition, and fitment before you pick a seller.

How to choose the right Camshaft Position Sensor for your car?

A cam sensor has to suit your exact engine, since the signal it produces must match what your ECU expects. The engine code matters most, and many engines run more than one of these sensors, so you'll need to know whether yours is the intake or exhaust camshaft sensor before buying. Confirm the OEM number first, then check the sensor type, the connector, the mounting location, and whether your engine uses variable valve timing, since VVT engines often take their own sensor.Feed your registration into Parthunt24 and the results shrink to sensors that fit your engine. Tap any listing and you're taken to the marketplace that holds it, where the description and the checkout are handled by the seller.
  • Vehicle compatibility: Match the make, model, year, engine code, and OEM part number.
  • Engine code: The most important compatibility factor.
  • OEM part number: The most reliable way to ensure correct fitment.
  • Intake vs. exhaust camshaft sensor: Some engines use separate sensors for each camshaft.
  • Sensor type: Hall-effect and other sensor technologies are not always interchangeable.
  • Connector type: Must match the vehicle’s wiring harness.
  • Mounting location: Verify the installation position and mounting design.
  • Cable length: Must match the original routing and connector placement.
  • Variable valve timing (VVT) compatibility: Some sensors are specific to VVT-equipped engines.
  • Transmission compatibility: Certain engine variants differ between manual and automatic models.
  • Condition: Check for damaged connectors, oil contamination, or cracked housings.

What to check before buying a Camshaft Position Sensor

When the seller's page opens, the connector and housing carry most of the story, since heat and leaking oil are what usually end these sensors. An oil-soaked plug or a cracked housing is a sign the sensor is on the way out, so make sure those are pictured up close rather than left to a single distant shot.
  • Photos: The sensor body, the connector, the mounting flange, and the cable.
  • Seller reputation: A long selling record with consistently good feedback.
  • Compatibility: OEM number and engine code, plus intake or exhaust position, against your car.
  • Included components: Sensor on its own, or with the O-ring and mounting bolt?
  • Condition: Oil contamination, a cracked body, corroded pins, or a damaged cable.
  • Testing: Word that the sensor was reading correctly on the donor engine.
  • Warranty and returns: Cover in case the sensor reads badly once fitted.
  • Shipping: The connector is protected and the tip is guarded so nothing arrives bent.
  • Documentation: The source engine's details and a note on how it was removed.
With the connector and housing looking right, finish up on the seller's page.

How much does a Camshaft Position Sensor typically cost?

What you'll pay for a camshaft position sensor depends on the engine, the brand, and how easily the part turns up. A used sensor for a common car sits around €8-€25, an OEM or VVT-specific sensor at €25-€70, and sensors for premium or recent engines beyond €110.Camshaft position sensor listings on Parthunt24 start from 5.00. The factors that move a camshaft sensor's price:
  • Brand: OEM-made sensors sit above unbranded aftermarket ones.
  • VVT compatibility: Sensors for variable-valve-timing engines tend to cost more.
  • Engine rarity: Sensors for common engines stay cheap; unusual engines climb.
  • Age of design: Sensors for current engines fetch more than discontinued ones.
  • Condition: A clean, oil-free sensor with undamaged wiring takes the higher price.

Faulty Camshaft Sensor? Inspect these surrounding parts too

A cam-timing fault rarely starts at the sensor alone, since the ECU reads it alongside the crank signal and the engine's timing parts. A worn timing belt or a failing crank sensor can throw the same codes as a dead cam sensor, so look these over before fitting a new one. Browse these on Parthunt24:
  • Crankshaft position sensor: Works in tandem with the cam sensor; a fault in one mimics the other.
  • Camshaft: Check the sensor target on the cam end for wear or damage.
  • Wiring harness: Chafed wiring to the sensor causes the same dropouts as a dead one.
  • Timing chain: A stretched chain shifts cam timing and throws correlation faults.
  • Timing belt: A slipped belt does the same and is worth checking on belt-driven engines.
  • Sensor O-ring: A perished seal lets oil onto the sensor and into its connector.
  • VVT solenoid: A sticking solenoid produces cam-timing faults that look like the sensor.
