KacuYelin Camshaft Position Sensor Set of 2 for GM 2.0–2.4L (2006–2017) OE fit, Sealed

KacuYelin camshaft position sensor set of 2 provides accurate camshaft timing data for compatible GM 2.0L–2.4L engines, restoring engine synchronization and reliable performance.

This pair of camshaft position sensors is designed to match OE fit and electrical connections for many Chevy, Buick, GMC, Pontiac and Saturn models from 2006–2017 with 2.0L, 2.2L and 2.4L engines. Each sensor uses a high-quality sensing chip and a strong magnet inside a fully sealed housing, built to tolerate heat, oil exposure and vibration. The kit lists multiple OEM cross-references (including 12577245, 2131690, 917-720) and fits a long list of factory engine applications — check your vehicle year, model and engine size before ordering to ensure compatibility.

Which vehicles will these sensors fit?

The set covers a broad range of GM platforms. It includes compatibility for model years across Chevrolet (Cobalt, HHR, Malibu, Equinox, Captiva Sport, Impala, Orlando), Buick (Regal, Verano, LaCrosse), GMC Terrain, Pontiac (G5, G6, Solstice) and Saturn (Aura, Ion, Sky, Vue) with 2.0L–2.4L engines. Use your vehicle’s year, submodel and engine displacement to confirm fit.

• Direct cross-references: 12577245, 2131690, 917-720 and other OEM numbers.
• Covers common GM 2.0/2.2/2.4L NA engines from 2006–2017.
• Verify via your car’s VIN or fitment tool for an exact match.

How does this camshaft sensor set impact engine operation?

Camshaft position sensors deliver the cam timing signal the engine control module needs to sequence fuel injection and ignition events. When the sensor outputs correct timing data, the ECU can synchronize valves, fuel delivery and spark timing more precisely, which supports smoother engine idle and steadier throttle response.

• Provides real-time camshaft position information to the ECU.
• Helps restore proper timing after replacing failed or intermittent sensors.
• Can reduce rough idling and erratic misfires caused by faulty cam signals.

What are the build and durability features to expect?

Each sensor in this set is fully sealed and fitted with a high-temperature FKM O-ring to resist oil and heat intrusion. An imported sensing chip and a neodymium magnet help ensure consistent signal strength; the assembly is designed to remain stable under engine heat and vibration encountered in daily driving.

• FKM O-ring and sealed housing for oil and heat resistance.
• Neodymium magnet and quality sensing chip for stable output.
• Manufactured in TS16949-certified facilities and EMC-tested for compatibility.

Are there installation or troubleshooting tips I should know?

Before installing, inspect the vehicle’s wiring connector and harness pins — bent or damaged pins will prevent a good electrical connection. Torque the sensor to factory specifications, avoid contaminating the sensing face with debris, and clear any stored fault codes after replacement to allow the ECU to relearn.

• Confirm connector pins are not bent, corroded or missing.
• Replace both sensors when applicable for consistent performance.
• After install, clear trouble codes and perform a short drive cycle.

Who is this for: This KacuYelin camshaft position sensor set is aimed at DIY mechanics, independent repair shops and fleet owners maintaining GM vehicles with 2.0–2.4L engines who need an OEM-compatible replacement. It’s a good choice when factory sensors fail, throw cam-related fault codes, or cause rough idling and timing-related drivability issues. Always verify fitment by year, model and engine size before purchase and inspect the vehicle connector for damage prior to installation.
