ACDelco Gold Throttle Position Sensor TPS 213-4668 (88864359) – Direct-Fit, OEM-Quality Signal

The ACDelco Gold 213-4668 (88864359) Throttle Position Sensor is a premium aftermarket TPS that accurately reports throttle-plate position to your engine control unit for reliable fuel and ignition management.

This ACDelco Professional throttle position sensor (TPS) is engineered as a high-quality replacement part to restore correct throttle-angle feedback on compatible vehicles. Built to match OEM dimensions and electrical characteristics, it provides consistent signal output so engine management can adjust fuel delivery and timing. Whether you’re repairing a driveability issue or performing routine maintenance, this ACDelco Gold sensor emphasizes fit, durability, and dependable performance.

How does the ACDelco Gold TPS communicate throttle position to the engine computer?

The TPS converts the mechanical angle of the throttle plate into an electrical voltage signal that the engine control module (ECM) reads. As the throttle opens or closes, the sensor’s internal potentiometer varies the voltage output, enabling the ECM to determine load and adjust fuel and ignition accordingly. A stable, linear signal helps avoid hesitation, surging, or poor idle control.

• Provides a smooth voltage curve corresponding to throttle angle
• Three-pin electrical connector for consistent signal transmission
• Bolt-on mounting matches factory location for correct alignment
• Designed to meet quality and durability expectations of aftermarket replacements

Will this ACDelco TPS fit my vehicle and install easily?

The ACDelco Gold 213-4668 is a direct-fit aftermarket replacement intended to match the original part’s dimensions and mounting points. Installation is typically straightforward: remove the old sensor, align the throttle shaft, secure the new unit with mounting bolts, and reconnect the wiring harness. No programming is usually required for compatible vehicles, but consult the vehicle’s service manual for any model-specific steps.

• Direct bolt-on design to match factory mounting
• Standard electrical connector compatible with specified applications
• Typically does not require ECU reprogramming for fitment
• Manufactured to meet or exceed aftermarket quality standards

What driving issues can this throttle position sensor help resolve?

Replacing a failing TPS often remedies symptoms related to incorrect throttle position feedback. Expect improvements in throttle response consistency, idle stability, and smoother acceleration once the ECM receives accurate angle information. While it won’t correct unrelated engine faults, it addresses the specific electrical signal pathway between the throttle plate and the engine computer.

• Reduces hesitation and uneven acceleration caused by faulty signals
• Improves idle quality and prevents unexpected stalls in many cases
• Helps eliminate throttle-related diagnostic trouble codes (when TPS is the cause)
• Delivers consistent operation across normal temperature ranges
