Aftermarket 12V Throttle Position Sensor Wear Potentiometer 17087654 17106682

The sensor operates by detecting the throttle valve position and converting mechanical rotation into an electrical signal. The signal voltage varies proportionally with throttle opening, providing the ECU with continuous, real-time data for fuel injection and ignition timing adjustments.

The Throttle Position Sensor 17087654 is identified by the following Original Equipment (OE) reference numbers and cross-references:

Cross-Reference Numbers:

• Intermotor 19909
• NTK TH47
• SS10429-12B1
• Lucas SEB847

Common Reference Designations:

• Throttle Position Sensor (TPS)
• Throttle Potentiometer
• Sensor Kit - Throttle Position

The Throttle Position Sensor 17087654 is designed for compatibility with a wide range of vehicles across multiple automotive manufacturers.

Important Compatibility Notes:

• This sensor is an Original Equipment (OE) number for General Motors, Opel, and Vauxhall vehicles
• Compatible with both manual and automatic transmission variants
• Always cross-check the OE reference number against the number found on your current unit to ensure proper fitment
• The list of compatible vehicles and years may not be complete; there may be additional vehicle applications compatible with this part

A failing or malfunctioning Throttle Position Sensor can produce a range of drivability issues. Below are the most common symptoms to watch for:

The most reliable indicator of a TPS problem is the check engine light accompanied by specific diagnostic trouble codes. Common DTCs associated with TPS failure include:

• P0120 – Throttle/Pedal Position Sensor/Switch "A" Circuit Malfunction
• P0121 – Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance
• P0122 – Throttle/Pedal Position Sensor/Switch "A" Circuit Low Input
• P0123 – Throttle/Pedal Position Sensor/Switch "A" Circuit High Input

The engine may not respond properly to driver input when the accelerator pedal is pressed. The vehicle may feel sluggish or unresponsive.

The vehicle may hesitate, jerk, or stumble during acceleration because the malfunctioning sensor fails to send proper throttle position data, causing an imbalance in the air-fuel mixture needed for smooth acceleration.

A faulty TPS can cause the engine idle speed to fluctuate unpredictably. The idle may be too high or too low, and the engine may be prone to stalling at idle. At slow speeds or stoplights, the idle may "jump around" frequently.

The engine may stall unexpectedly—particularly when stopping or at idle—as the ECU receives incorrect throttle position signals and fails to maintain proper air or fuel delivery.

The vehicle may experience surging or "bucking" while maintaining a steady speed, as the ECU receives fluctuating throttle position signals.

Since the ECU relies on throttle position data to determine the correct air-fuel ratio, a defective sensor may cause the engine to run either too rich or too lean, significantly reducing fuel efficiency.

A malfunctioning TPS can cause harsh, delayed, or erratic shifting in automatic transmissions. The ECU uses TPS data as one of the inputs for shift timing; incorrect data can lead to aggressive or late shifts.

• Wear and tear – Internal potentiometer tracks wear over time due to repeated throttle movements
• Physical damage – Impact or mechanical stress can damage the sensor housing or internal components
• Electrical fatigue – The sensor may fail due to fatigue or electrical malfunction
• Moisture ingress – Liquid intrusion can cause corrosion and electrical shorts

When sourcing or purchasing the Throttle Position Sensor 17087654, consider the following factors to ensure optimal performance and compatibility:

Always confirm that the part number on your existing sensor matches 17087654. Related numbers include 17106682, 17111822, 817203, 817204, and 0817203. Cross-check the OE reference number against the number found on your current unit before purchasing.

Ensure the sensor is compatible with your specific vehicle make, model, year, engine size, and transmission type. This sensor is primarily designed for General Motors (Buick, Cadillac, Chevrolet, GMC, Oldsmobile, Pontiac), Opel, and Vauxhall vehicles. Selecting the wrong sensor can lead to poor engine response or persistent check engine light issues.

Verify that the sensor features a 3-pin round connector and operates with anticlockwise rotation. Confirm that the operating voltage is 12V DC.

Confirm that the connector type and pin configuration match your vehicle's wiring harness. This sensor features a round 3-pin connector.

Look for sensors constructed with durable materials such as corrosion-resistant stainless steel and durable plastic composites. High-quality sensors are built to the same dimensional and material standards as the original part they replace, ensuring reliable performance and a long service life.

Prioritize products that meet or exceed OEM standards and automotive quality management system certifications. Suppliers adhering to rigorous quality controls demonstrate commitment to product reliability and consistency.

When sourcing from suppliers, evaluate their technical capabilities, quality assurance processes, and production capacity. Look for evidence of:

• Strict quality control standards meeting OEM specifications
• Multiple inspections and testing before shipment
• Full manufacturer traceability
• Positive customer reviews and ratings

The sensor features a compact design (approximately 81 x 42 x 40 mm) for direct throttle body mounting. Professional installation is required. During installation, ensure that:

• The sensor is properly aligned with the throttle shaft
• Mounting screws are tightened to the correct torque specification
• The connector is securely fastened
• Sensor wires are not routed over sharp edges
• Proper clearance is maintained from ignition HT leads, coil leads, and other sources of electrical interference

After installation, it is recommended to verify the sensor operation using a diagnostic scan tool. Check that the throttle position readings are smooth and consistent throughout the full range of throttle movement and that the check engine light is no longer illuminated.

Consider products that come with warranty coverage and technical support. A warranty can provide assurance of product quality and reliability. Some manufacturers offer warranty coverage of up to 3 years.

• The sensor is a slider-type potentiometer device that provides continuous variable resistance output proportional to throttle position
