Detailed Description

Dorman 962-277 is engineered as an OE-style engine camshaft position sensor for vehicles that rely on accurate camshaft signal input to the ECU. When the original sensor fails from heat exposure or internal component damage, this replacement restores the signal path needed for stable engine operation. It cross-references Standard Ignition PC975 and Spectra Premium S10349 for the same application. This part number 962-277 is listed for many GM platforms, including Chevrolet Camaro, Chevrolet Silverado 1500, and GMC Sierra 1500, making it a practical choice for service work on late-model trucks, SUVs, and performance cars.

What It Helps Address

• Camshaft position sensor fault codes
• Hard starting or extended crank conditions
• Rough idle or inconsistent engine timing signals
• Check engine light related to camshaft sensor performance
• Engine stalling caused by loss of camshaft position input

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. Inspect the connector and wiring for heat damage, corrosion, or bent terminals before replacing the sensor.
