A-NAFTULY Camshaft Position Sensor Set — 4-Pack 12615371 Replacement for GM 3.6L V6 (Improves Starting & Idle)

A-NAFTULY's set of four camshaft position sensors (OEM ref 12615371) replaces worn units to restore accurate cam timing across many GM 3.6L V6 vehicles.

If your Chevrolet, GMC, Buick, Cadillac or related GM vehicle with a 3.6L V6 is showing rough starts, misfires, or an illuminated check engine light, the camshaft position sensor is often a primary suspect. These A-NAFTULY sensors are precision-built to match original mounting and electrical connectors and are supplied as a convenient four-pack when multiple cylinders or bank sensors need attention.

How will replacing these sensors affect engine starting and idle?

Replacing a failing camshaft position sensor can quickly improve engine start-up reliability and smooth the idle. The sensor reports camshaft position to the engine control unit, helping it to time spark and injection accurately.

• Restores consistent ignition timing for cleaner starts
• Reduces rough idle and minimizes stalling incidents
• Helps clear cam-related diagnostic trouble codes once installed
• Sold as a set of four for full-bank servicing or future spares

What should I check before ordering and installing?

Confirming fitment and comparing the old sensor to the new unit prevents returns and ensures a proper electrical and mechanical connection. Check mounting points, connector type, and the OEM reference numbers shown in the product references.

• Compare connector pin layout and locking tab to your original sensor
• Verify OEM reference numbers like 12615371 or 12684186 match
• Inspect sensor mounting hole alignment and seal surface for fit
