Buick / Chevrolet 2-Pin Camshaft Position Sensor Connector – OEM 13520101 / 15490464

Direct OEM-specification replacement for the Buick and Chevrolet 2-pin camshaft position (CMP) sensor harness connector. Cross-references OEM part numbers 13520101, 15490464, and 1121700215NF002. Used in camshaft position sensor harnesses across Buick and Chevrolet petrol engine platforms. Available bare or with 15cm pre-wired leads.

Why Camshaft Position Sensor Connectors Fail

The camshaft position sensor is mounted on the cylinder head or timing cover, in direct contact with engine oil vapour and heat. The 2-pin connector is exposed to oil contamination, which degrades the terminal plating and increases contact resistance over time. A corroded CMP connector causes the ECU to lose the camshaft timing signal, which is used for sequential fuel injection and variable valve timing (VVT) control. The result is a range of symptoms that are frequently misdiagnosed as a failed CMP sensor or VVT solenoid:

• P0340 / P0341: CMP circuit malfunction or range/performance — ECU cannot determine camshaft position
• Rough idle and misfires: Sequential injection timing is disrupted when the ECU loses the CMP signal
• VVT not activating: On engines with variable valve timing, the ECU uses the CMP signal to calculate cam phaser position — a corroded connector causes VVT to default to the base timing position
• Hard start when hot: The ECU uses the CMP signal for hot-start fuel injection sequencing — a corroded connector causes extended cranking before the engine fires

Frequently Asked Questions

Q: My Buick Regal has P0340 and rough idle — is it the connector or the sensor?
A: P0340 with rough idle on Buick Regal is frequently caused by a corroded 2-pin CMP connector rather than a failed sensor. The connector is located near the top of the engine where oil vapour accumulates, accelerating terminal corrosion. Inspect the connector before replacing the CMP sensor.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
