GDUKOP Camshaft Position Sensor 2pcs OE-Fit Replacement for Hyundai & Kia, Corrosion-Resistant

GDUKOP's 39350-23910 camshaft position sensor pair accurately monitors camshaft timing to restore smooth starting, steady idle, and better throttle response.

If your Hyundai or Kia shows hard starting, rough idle, or reduced acceleration, a worn camshaft position sensor can be the culprit. These two GDUKOP sensors are designed as direct replacements for OE part numbers such as 39350-23910 and PC661, offering plug-and-play fitment for a long list of vehicles from 2004–2021. Built with corrosion-resistant materials and precision manufacturing, they meet OE standards so installation is straightforward and performance is consistent.

How will these sensors affect engine starting and idle?

Camshaft position sensors send timing data to the engine computer so fuel injection and ignition timing are correct. Replacing a faulty sensor helps the ECU recalibrate timing, which can eliminate hard starts and reduce rough idling. You should see smoother cold starts and more stable idle RPM once the sensor is functioning correctly.

• Restores accurate camshaft timing signals to the ECU
• Reduces misfires and inconsistent idle behavior
• Improves cold-start responsiveness

Which models and OE numbers are these sensors compatible with?

This 2-piece set fits many Hyundai and Kia models, including Elantra, Elantra GT, Elantra Coupe, Tiburon, Tucson, Forte, Forte Koup, Forte5, Soul, Spectra, and Sportage across specified years. They replace several OE and aftermarket reference numbers so you can match by part number before buying. Always verify your vehicle’s existing part number and connector style before installation.

• Replaces OE numbers: 39350-23910, 39350-23700, PC661 and others
• Fits Hyundai 2004–2015 Elantra, 2013–2017 Elantra GT, 2005–2008 Tiburon
• Fits Kia 2010–2016 Forte/Soul/Sportage and related model years listed

What should I know about installation and durability?

GDUKOP sensors are manufactured to precise tolerances for a straightforward plug-and-play replacement; no special programming is typically required. Inspect the vehicle’s wiring and connector pins before installing—bent or damaged pins can prevent proper operation even with a new sensor. The sensors are built with corrosion-resistant materials to withstand engine-bay conditions and deliver long-term reliability.

• Plug-and-play design for direct swap with original sensor
• Check connector pins and wiring before installation
• Corrosion-resistant housing for extended service life

What improvements can I expect after fitting these sensors?

Once replaced, you can expect more consistent engine performance: fewer starting issues, steadier idle, and improved throttle response under load. While sensors don’t fix mechanical engine faults, they restore critical timing feedback so the ECU can manage fuel and spark more effectively. If related trouble codes remain, further diagnostics will reveal if other components need attention.

• Better throttle response and acceleration consistency
• Reduced engine shaking and misfire symptoms
• Helps clear camshaft-related diagnostic trouble codes when sensor is faulty

Who is this for: this dual-pack from GDUKOP is aimed at DIY mechanics and professional technicians who need a reliable, cost-effective replacement for worn camshaft position sensors on a range of Hyundai and Kia vehicles. It’s ideal when OE-compatible parts and quick installation are required—confirm the existing part number and connector condition to ensure a smooth swap.
