Oxygen sensors, also known as Lambda sensors or O2 sensors, are among the most sensitive and critical components on your car's engine. They monitor the air/fuel mixture under idle, moderate acceleration, and cruise conditions. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio than the newer wide range air/fuel sensors (A/F sensors). Today's engines may use as many as four oxygen sensors to monitor exhaust gas oxygen content and catalytic converter efficiency. In order to perform these functions properly, Denso oxygen sensors adhere to strict OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt drivability and illuminate the check engine light, resulting in costly and time-consuming repairs. Denso First Time Fit oxygen sensors are designed to meet those tolerances and more. Key features and benefits of Denso Oxygen Sensors include: * Robotic laser welds * Porous PTFE filters block efficiency-robbing contaminants * Double-protection covers maintain proper temperature for quicker response times and protect ceramic elements from silicone and lead fouling * Rugged, watertight stainless steel housings resist corrosion and contamination * Aluminum oxide trap layers keep silicone and lead out, preventing damage to the platinum electrode * Refined zirconia elements improves sensor response * Superior design maximizes engine performance while reducing fuel consumption and harmful emissions * First Time Fit design delivers the right part the first time

The knock sensor is able to detect mechanical stress and produces a voltage when the car knocks or pings. Under heavy acceleration, it sends signals to the ECU and the ECU retards the ignition timing to compensate for the knocking, which in effect protects the pistons and rings from damage. Knocking also occurs when using low-grade fuel and having the knock sensor allows you to use different grade fuels without causing engine damage. Holstein Parts focuses on using only the highest quality materials, manufactured to exacting standards for an aftermarket product that is truly built to match or exceed the OE part. Holstein Parts knock sensors line has superior coverage for domestic and import applications.

Standard Motor ABS speed sensors supply information regarding wheel movement to the ABS computer. They're often located at each wheel hub/rotor on 4-wheel disc systems. Alternatively, on rear drum applications, you'll usually find them mounted on the differential housing. Under braking, if wheel speeds are unequal, indicating wheel lockup, the computer modulates the anti-lock feature until the speeds are equal again. Replacement ABS speed sensors are available for hundreds of makes/models. Just match up your vehicle specs to order the correct unit.

The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in a vehicle's electronic control system (ECU). The MAP sensors provide instantaneous manifold pressure information to the engine's computer (ECU). The data is used to calculate air density and determine the engine's air mass flow rate, which determines the required fuel metering for optimum combustion and influences the advance or retard of the ignition timing. A faulty Map sensor can cause a vehicle to run rich or lean, which will affect the vehicle's ignition timing and cause the engine not to run smoothly. Holstein Parts uses only the highest quality materials and engineering for parts that are truly built to match or exceed the OE part. Holstein Parts MAP sensors offer superior coverage for domestic and import applications.
