Detailed Description

Prenco 4D-1102 is built for vehicles that rely on accurate crankshaft position input to maintain proper ignition timing and engine control. This sensor uses a single oblong female connector with three male blade terminals, making it a straightforward replacement for the original sensor on supported applications. It cross-references Standard Ignition PC276 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. The Prenco 4D-1102 is a practical replacement when servicing crankshaft signal faults on these GM platforms.

Common Uses

• Restoring crankshaft position signal loss
• Addressing engine stalling or intermittent no-start conditions tied to sensor failure
• Correcting rough running caused by inaccurate crankshaft speed input
• Replacing a damaged connector or worn sensor body during ignition repair
• Resolving diagnostic trouble codes related to crankshaft position sensing

Installation Notes

Verify the lower sensor location and connector style before installation. Inspect the harness connector, terminals, and mounting surface for corrosion or damage, and confirm the sensor seats correctly without forcing the connector. Always match the application by year, make, model, and position before ordering or installing Prenco 4D-1102.
