Holstein Parts MAP Sensors
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.

Holstein Parts Knock Sensors
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.

Holstein Parts Blower Motor Resistor Connectors
Holstein Parts blower motor resistor connectors are replacement electrical plugs that link a vehicle's wiring harness to the HVAC blower motor resistor. Because electrical resistance generates high heat, the original connectors often melt, requiring a replacement. These harnesses restore proper fan speed control and stop system failures. Additional details: * OEM Fitment: Designed to match the exact OE specifications for European, Asian, and domestic vehicles, ensuring a secure and exact connection * High-Temperature Materials: Built to withstand the extreme electrical currents and heat cycles that typically cause inferior connectors to melt or corrode * Pre-stripped/Pigtail Design: They come with attached wire leads to allow technicians to easily splice the new connector into the vehicle's factory wiring harness
