The engine lubrication system is critical to engine operation and long life. On some vehicle applications, the engine control module monitors the engine oil level to ensure lubrication is not lost.

An ACDelco Professional, premium aftermarket Engine Oil Level Sensor is a high quality replacement for many vehicles on the road today. It measures the oil level in your vehicle’s oil pan and will send warnings to the information center or dash panel if oil levels reach a level that is too low, as determined by General Motors engineers. This premium aftermarket replacement engine oil level sensor is manufactured to meet your expectations for fit, form, and function.

A leader in vehicle electronic solutions, each premium product meets or exceeds OE specifications in appearance, fit, and function, ensuring easy installation and excellent performance. The product has been tested under extreme environments.

The Crankshaft Position Sensor plays a vital role in your engine’s operation, to determine the exact position of then engine’s crankshaft to the ECM. The ECM then uses this information to determine fuel and spark timing or engine misfire detection. A failed sensor can result in a check engine light, failure to start, intermittent stalling, or misfire. Crankshaft Position Sensors are a premium quality product with outstanding support and leading innovation bred from our OE heritage.

ACDelco GM Original Equipment Engine Crankshaft Position Sensors monitor the position and rotational speed of the crankshaft, and are GM-recommended replacements for your vehicle’s original components. The signal from the crankshaft position sensor is used by the engine control module to determine fuel injection and ignition timing. These original equipment engine crankshaft position sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

This engine crankshaft position sensor is designed to match the fit and function of an original sensor to help ensure the engine control unit receives proper inputs when an original sensor has failed from heat or internal component damage.

Carquest Premium crankshaft position sensors are designed to perform in harsh engine environments and meet or exceed original equipment (O.E.) specifications.
