The pressure inside the intake manifold is an extremely important input to the engine control unit. Holley Sniper MAP sensors respond to changes in manifold pressures and relay the information to the ECU in the form of a voltage signal ranging from 1-5 volts. These replacement sensors will handle applications up to 25 lbs. of boost. Additional notes: * Utilizes stock attaching points * Sensor monitors manifold vacuum, varying output voltage to the ECU as a function of load placed on the engine—providing necessary data to control fuel enrichment

Standard Motor Products replacement throttle position sensors help you get maximum fuel efficiency and power from your engine. A properly operating accurate throttle position sensor is an essential component to helping your vehicle run flawlessly. The throttle position sensors transform the throttle position into output voltage and emit the voltage signal to your vehicle's computer. In addition, the sensors detect the opening and closing speed of the throttle valve and feed the voltage signal to the vehicle's computer. The computer receiving the signal from the throttle position sensor determines optimum engine operating conditions for idle control, fuel enrichment, and fuel cut. Replace your vehicle's worn or malfunctioning throttle position sensor with one of these reliable Standard Motor Products replacement TPS sensors.

MSD offers replacement wiring harnesses for the Power Grid Dual NTK wideband oxygen module—a dual channel air/fuel ratio (AFR) system designed to interface with the Power Grid (P/N 7730) to monitor and record the AFR of internal combustion engines. The oxygen sensor module is capable of measuring AFR as low as ? = 0.5 (7.35:1 gasoline AFR equivalent). The AFR range is configurable using the MSDView software in conjunction with the Power Grid Controller (P/N 7730). Excellent MSD range of the NTK sensor gives each unit the ability to accurately monitor AFR's even on alcohol cars. The MSD wideband oxygen sensor module also provides a 0.5-4.5 VDC analog output proportional to the AFR. This analog output can be sent to a gauge or a data acquisition system. A dual-color LED provides the system status at a glance. (To provide accurate backpressure compensated AFR readings on turbocharged applications, the addition of an Exhaust Pressure Module, part number 7767, is required.) MSD can provide a replacement main harness, sensor 1 harness, or sensor 2 harness for your application. Order the model needed to restore proper performance to your vehicle.
