HELLA 6PX 008 476-331 Throttle Position Sensor

The HELLA 6PX 008 476-331 is a high‑performance throttle position sensor (TPS) designed for modern internal combustion engines. It delivers precise throttle angle data to the engine control unit, enabling optimal fuel injection, ignition timing, and overall vehicle performance.

Key Features

• Voltage Supply: 12 V DC – compatible with standard automotive electrical systems.
• Connector: 3‑pin rectangular plug – ensures a secure, tamper‑resistant connection.
• Signal Output: Analog voltage ranging from 0.5 V to 4.5 V, representing the throttle plate position from closed to fully open.
• Operating Temperature: -40 °C to +125 °C – suitable for a wide range of climates and engine bay conditions.
• Mechanical Design: Compact rectangular housing with robust sealing against oil, coolant, and vibration.

Applications Across Vehicle Brands

The sensor is engineered to fit a broad spectrum of vehicles. It is widely used in models from major manufacturers such as Audi, BMW, Chevrolet, Dodge, Ford, Honda, Hyundai, Kia, Mercedes‑Benz, Nissan, Subaru, Toyota, Volkswagen, and many others. Its universal design allows it to replace OEM units in both domestic and international markets.

Installation & Compatibility

Installing the HELLA 6PX 008 476-331 is straightforward:

1. Disconnect the vehicle’s battery to prevent electrical shock.
2. Remove the existing throttle position sensor by unscrewing the mounting bolts and disconnecting the wiring harness.
3. Align the new sensor’s rectangular connector with the vehicle’s TPS socket, ensuring a snug fit.
4. Screw in place and reconnect the battery.

Because of its standardized pin layout and voltage specifications, the sensor is fully compatible with most engine control modules (ECMs) that originally used a TPS from the same manufacturer or equivalent.

Performance Benefits

• Accurate Throttle Mapping: Provides real‑time data for precise fuel metering and ignition timing, improving throttle response.
• Enhanced Fuel Efficiency: By maintaining optimal air‑fuel ratios, the sensor contributes to better mileage.
• Reduced Emissions: Accurate throttle control helps meet stringent emission regulations.
• Reliability: Durable construction resists wear from repeated throttle movements and harsh engine bay environments.

Technical Specifications

Quality Assurance & Standards

The sensor is manufactured under strict quality control protocols and complies with automotive industry standards such as ISO/TS 16949. It undergoes rigorous testing for electrical performance, mechanical durability, and environmental resistance.

Maintenance Tips

• Inspect the connector regularly for corrosion or loose pins.
• Avoid exposing the sensor to excessive oil or coolant leaks; use a protective gasket if necessary.
• If throttle response feels sluggish, check for electrical noise or grounding issues before replacing the sensor.

Conclusion

The HELLA 6PX 008 476-331 Throttle Position Sensor is a reliable, high‑precision component essential for modern engine management systems. Its robust design, universal compatibility, and proven performance make it an ideal choice for vehicle owners seeking to maintain or restore optimal throttle control.
