Throttle Position Sensor – Black CCW Rotation 8mm D-Shaft

Dynamic Engine Control: TPS Black CCW (8mm D-Shaft)

The Throttle Position Sensor – Black CCW Rotation is the definitive instrument for measuring throttle angle on counter-clockwise rotating spindles. Featuring a precision 8mm D-shaft interface, this sensor is engineered for specific performance throttle bodies often found in K-swap, SR20DET, and custom Mazda Rotary builds. In a professional standalone ECU integration, the TPS signal is the master variable for acceleration enrichment and load detection. By providing a clean 0-5V output, this black CCW sensor ensures that your Ignition Timing and fueling are perfectly synchronized with driver demand.

Engineering Principles: CCW Potentiometric Response

This black-housed sensor is internally configured to provide an increasing voltage signal (towards 5V) as the shaft rotates Counter-Clockwise (CCW). This Analogue-to-Digital interface (concerning throttle angle) is critical for fuel map calibration, as it allows the ECU to maintain a high-resolution window into the engine’s transient state. The internal resistive element is designed for motorsport longevity, featuring high-cycle durability that prevents the “dead spots” common in cheap OEM replacements. This consistency is foundational for achieving Maximum Brake Torque (MBT) timing across the entire RPM range.

Operational Benefits for Sequential Control

For the professional tuner, the Black CCW TPS provides a level of reliability that is essential for closed-loop boost control strategies. By knowing the exact throttle position, the ECU can implement anti-lag strategies, launch control arming, and pit-lane speed limiters. In high-horsepower RB26 or 2JZ builds utilizing large single throttle bodies, this sensor’s 8mm D-shaft ensures a zero-backlash connection, providing an instantaneous speed signal to the ECU. This allows for a more aggressive traction control strategy, as the ECU can react to throttle-induced tire slip with millisecond precision.

Installation and Harness Integration

The Black CCW TPS kit is designed for a complete harness integration solution. It includes the throttle position sensor, matching opposing connector, and 3 precision pins. This eliminates the need for unreliable pigtails and ensures a motorsport-grade weatherproof connection. The sensor is compatible with all Haltech Elite and Nexus ECUs and is a universal component for any system requiring a CCW throttle signal. During setup, it is mandatory to perform a TPS calibration in the ECU software to map the 0% and 100% endpoints, ensuring that the standalone ECU integration utilizes the full signal resolution.
