Ambient Temp Sensor

CARQUEST premium engine management products provide the right products for a wide range of domestic and import applications. Delivering the highest performance and durability under demanding conditions.

The Premium CarQuest Vehicle Solutions line is designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Relief Valve is used in the automotive air conditioning system to prevent unusual over-pressure that may cause damage to critical components within the system or to the system as a whole. By opening it’s valve when the system pressure exceeds the preset pressure levels and closing when the internal pressure decreases to the preset pressure levels, proper factory designated system pressures are maintained.

Product Features:

• Made to OE spec to ensure a proper fit, form and function.
• Sensors are engineered for precision performance, durability and a long service life.
• All units are tested using advanced end-of-line testing equipment that pressurizes the A/C Pressure Relief Valve and checks functionality to ensure each A/C Pressure Relief Valve meets manufacturing specifications before packaging.

CARQUEST MAP sensors are manufactured with critical OEM components to ensure that your engine runs efficiently to reach the best gas mileage on your vehicle.

Product Features:

• CARQUEST MAP sensors connectors are exact OE fit to ensure the proper vacuum is maintained to prevent power loss and to minimize internal contamination.
• CARQUEST MAP sensors utilize high temperature resistant seals. Damaged seals can directly impact the vehicles fuel-to-air ratio, making it less fuel efficient.
• CARQUEST MAP sensors are 100% individually tested for all product functionalities including proper vacuum seal and electrical output.

The Delphi Wide Range Oxygen Sensor is an integral component in the engine management system, helping provide accurate engine control and system diagnostics. It measures the air-fuel ratio of exhaust gases over a wide lambda range. Its five-wire, two-cell design enables higher signal resolution with greater accuracy. An integrated heater and alumina-zirconia element facilitate a fast light-off, allowing earlier closed-loop operation compared to conventional conical oxygen sensors. Designed to accommodate a variety of fuel applications, the poison-resistant coating of the Delphi Wide Range Oxygen Sensor helps improve accuracy and durability in harsh exhaust environments, while minimizing deterioration of the sensor characteristics over time. Its uniquely designed planar element technology and integral heater enhance resistance to thermal shock and help the sensor achieve fast light-off to help manufacturers meet current and more stringent future emissions regulations. The sensor’s greater accuracy and a fast transient response time help provide greater engine control, and help improve fuel economy and drivability.

Product Features:

• High signal resolution and low pressure sensitivity help provide precise engine control
• Integral heater enables faster light-off for earlier closed-loop operation
• Unique planar element design enhances thermal shock resistance
• Fast response helps improve fuel economy

Walker Oxygen Sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements.

Product Features:

Denso First Time Fit oxygen sensors are constructed of the highest quality materials available. High-quality stainless steel, porous polytetrafluoroethylene (PTFE), fluorine rubber, aluminum oxide, high-grade platinum and ceramics are used in each DENSO sensor.

Product Features:

• SUPERIOR DESIGN – Maximizes engine performance and fuel efficiency while reducing harmful emissions.
• DOUBLE-PROTECTION COVER – Maintains proper unit temperature for quicker response times and protects the ceramic element against silicone and lead poisoning.
• ALUMINUM-OXIDE TRAP LAYER – Keeps silicone and lead outside the ceramic element through DENSO’s exclusive design, preventing damage to the platinum electrode.
• STAINLESS STEEL HOUSING – Resists corrosion and contamination with a rugged, watertight body.

The Bosch oxygen sensor utilizes a mix of zirconium and yttrium oxides and other elements to form a tough base that withstands the intense stress to which oxygen sensors are subjected. Each element is incredibly strong for best-in-class performance and maximum service life.

Product Features:

• OE-Equivalent.
• Direct fit for easy installation.
• OE Style connectors and wire lengths.
• Base ceramic probe of Zirconium and Yttrium.
• Patented Platinum Power Grid.

The ACDelco GM Original Equipment Oxygen (O2) Sensor is a GM-recommended replacement for your vehicle’s original component. The Oxygen (O2) Sensor is a special feedback sensor on your vehicle’s exhaust system. This sensor measures the proportion of oxygen in the exhaust gases. Using this measurement, the engine management computer can adjust the air/fuel ratio near the optimum value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized. This original equipment oxygen sensor has been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors. When you are looking for a match to GM Original Equipment specifications in a replacement part for your GM vehicle, trust ACDelco to get the job done.

Product Features:

• Detect oxygen content in the exhaust gases to optimize emissions and fuel economy
• GM-recommended replacement part for your GM vehicle’s original factory component
• Offering the quality, reliability, and durability of GM OE
• Manufactured to GM OE specification for fit, form, and function

Oxygen Sensor

Oxygen Sensor

NTK is the world’s largest supplier and manufacturer of OEM oxygen sensors. Oxygen sensors play a critical role as part of the vehicle’s on-board diagnostic system in maintaining optimal engine performance, maximizing fuel efficiency and reducing harmful emissions. While conventional switching oxygen sensors only switch rich or lean, wideband oxygen (or Air-Fuel Ratio) sensors produce a linear output signal that allows the ECU determine exactly how rich or lean an engine is running and make continuous and precise adjustments of the air-fuel mixture to stay closest to stoichiometric, providing the best possible combustion and fewest emissions. A ceramics company at our core, NTK uses state-of-the art technology enabling complete control of the ceramics used in our wideband oxygen sensors from raw material to finished product. Trust The Sensor Specialist for full-line market support and OE application technology.
