Standard Ignition PC276 Engine Crankshaft Position Sensor - Lower

Engine Crankshaft Position Sensor for OE-Style Timing Control

Standard Ignition PC276 is an engine crankshaft position sensor built for accurate crank signal monitoring and stable ignition timing. It is a direct-fit style replacement for select Cadillac, Pontiac, and Oldsmobile applications, including Cadillac DeVille, Cadillac Seville, Cadillac Eldorado, Pontiac Bonneville, and Oldsmobile Aurora lower-position installations.

Key Features

• Bolt-on attachment with a single oval plug-in connector
• Female connector with 3 male blade terminals
• Integrated A/D conversion and digital signal processing for precise signal output
• Dynamically adaptive switch point for improved timing accuracy
• Electromagnetic field and power spike protection built into the circuitry
• Custom magnetic circuit calibration for consistent target wheel alignment
• 100% environmental, endurance, timing, pulse width, and signal amplitude testing

Detailed Description

The Standard Ignition PC276 crankshaft position sensor monitors crankshaft position and sends a clean digital signal to the engine control system. Its adaptive circuitry and calibrated magnetic design help maintain accurate timing between the target wheel and sensor output, which is important for smooth engine operation and reliable ignition control. This part cross-references Dorman - OE Solutions 917-799 for the same application.

Compatible With 2000-2005 Cadillac DeVille, lower; 2000-2004 Cadillac Seville, lower; 2000-2002 Cadillac Eldorado, lower; 2001-2003 Oldsmobile Aurora, lower; and 2004-2005 Pontiac Bonneville, lower. Standard Ignition PC276 is also listed across multiple interchange references for service matching on these vehicles.

What It Helps Resolve

• Crankshaft position sensor fault codes
• Intermittent no-start or hard-start conditions
• Rough idle caused by unstable crank signal input
• Stalling related to incorrect engine timing data
• Misfire concerns tied to inconsistent sensor output

Installation Notes and Tips

Verify the connector shape, terminal count, and lower mounting location before installation. The bolt-on design and plug-in electrical connection support a straightforward replacement process, but the sensor should be installed with the target wheel and harness routing checked for proper alignment and clearance. Confirm the vehicle application by year, make, model, and position before ordering PC276.

Quality Assurance

Standard Ignition uses controlled manufacturing and testing processes from component selection through finished product inspection. PC276 is evaluated for timing, pulse width, and signal amplitude, with additional environmental and endurance testing to support consistent sensor performance.
