Help your engine computer read pedal position with the Standard Ignition Accelerator Pedal Sensor APS594, a direct-fit OE replacement LaCrosse sensor for the 2018-2019 Buick LaCrosse that also fits the 2016-2018 Chevrolet Malibu. Mounted at the accelerator pedal, this sensor reports how far the pedal is pressed so the throttle system can respond to driver input.
- Quality control: Built by a global manufacturer that keeps complete quality control throughout the manufacturing process.
- OE-matched outputs: Designed to hold specific installed outputs that match OE, instead of relying on an adjustable consolidated design.
- Direct-fit OE replacement: Intended to restore proper accelerator pedal sensor function when the original sensor has failed.
- End-of-line tested: Each unit goes through end-of-line testing with thousands of data points to validate its output voltages.
This new sensor has a black polyamide 6 construction and ships with the pedal assembly included. Linkage is not attached. It connects through one rectangular, plug-in female connector with six male pin terminals and bolts on at the accelerator pedal. Hardware and mounting brackets are not included, so consult the vehicle service information for the correct fasteners and whether the originals may be reused. The listed applications use one sensor per vehicle. Country of origin: Mexico.
Signs this part may need replacing: a warning light, hesitant or erratic throttle response, or reduced engine power. These symptoms can have other causes, so diagnose the system before replacing the sensor.
