1999 GMC Sierra 2500 Throttle Position Sensors

ACDelco GM Original Equipment Throttle Position Sensors (TPS) are electrical sensors, and are GM-recommended replacements for your vehicle’s original components. They electronically inform the engine control module (ECM) of the throttle’s plate angle or position. These signals are then used to regulate the fuel and ignition system. These original equipment throttle position sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Product Features:

• Electronically informs the ECM of the throttle valve angle
• Used to regulate the fuel and ignition system
• 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

Designed digital output for maximum signal to noise ratio. Not impacted by temperature changes and provide robust, long-lasting sensor protection. Manufactured to meet or exceed OE requirements.

Delphi Digital Speed and Position Sensors are based on integrated adaptive threshold Hall effect technology. They sense the speed and position of a target created with various sense features that are machined, stamped, drawn, or magnetically encoded. They can sense speeds as low as zero RPM. Delphi Speed and Position Sensors feature silicon Hall sense elements. The sensor assembly uses proven design features and assembly processes to provide a reliable solution in demanding automotive environments. The sensor design is modular to enable re-use of proven components and to provide low risk package modifications for new applications. They utilize an adaptive threshold control scheme providing robust performance that improves the air gap capability and reduces the placement accuracy requirements between the sensor and the target. Delphi also offers designs that help protect the sensor from transients and from electromagnetic interference (EMI). Power can be provided by either battery or regulated voltage supplies, enabling even more controller flexibility. Delphi’s Digital Speed and Position Sensors can operate on conditioned voltage from 4.5 to 16 volts.

Product Features:

• Modular design based on proven features and assembly processes provides rapid application optimization with flexible package geometry and high reliability
• Three-wire open collector output, open drain output, or two-wire current output allow flexible controller design
• Accurate square wave output eliminates square-up function in the controller
• Transient protection helps protect against stray electro-magnetic fields interface
• Various mounting applications provide choice of many existing designs, or custom designs
• Adaptive Hall signal schemes provide improved timing accuracy, optimized sensor air gap and tilt sensitivity, and zero speed sensing capability
• Single element option offers simplified design, and valid power on state (VPOS) for camshaft applications to minimize engine synchronization timing
• Dual element differential option offers extremely accurate gear edge detection, peak detector circuitry that is immune to tilt or off-center failure mode, and gain-adjust circuitry that reduces the effect of minor gear anomalies
• Enhanced sensing capability helps reduce emissions and improve reliability and drivability
