93740916 Throttle Position TBS Sensor For Daewoo Opel Vauxhall GM Buick Cadillac

The sensor operates by measuring the angle of the throttle valve and providing the ECU with up-to-date information regarding throttle position. The signal voltage varies proportionally with throttle opening, providing the ECU with continuous, real-time data for fuel injection and ignition timing adjustments. The clockwise rotation direction ensures compatibility with the throttle shaft orientation in the designated vehicle applications.

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 dashboard warning light (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 sensor may send inaccurate or intermittent signal outputs to the ECU, causing the engine management system to receive incorrect throttle position data.

The throttle may become unresponsive or delayed when the accelerator pedal is pressed. This occurs because the ECU is not receiving accurate position data to adjust fuel delivery and ignition timing accordingly.

The most common symptom of a faulty TPS is hesitation whenever the accelerator is pressed. The vehicle may jerk or stumble 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, leading to rough idling or "hunting" RPMs.

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" during acceleration, especially at low speeds or when transitioning from a stop. The engine may also struggle to maintain speed.

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.

A failing TPS can cause a noticeable loss of power or torque, as the engine may not receive sufficient fuel and air.

• Wear and tear – Internal potentiometer tracks wear over time due to the constant contact of the movable wiper arm over the sensor element
• Physical damage – Impact or mechanical stress can damage the sensor housing or internal components
• Faulty electronics – Internal electronic components may degrade over time
• Liquid damage – Moisture ingress can cause corrosion and electrical shorts
• Heat exposure – Prolonged exposure to high under-hood temperatures can degrade internal components

When sourcing or purchasing the Throttle Position Sensor 93740916, consider the following factors to ensure optimal performance and compatibility:

Always confirm that the part number on your existing sensor matches 93740916. Alternate formats include 93 740 916. Cross-check the OE reference number against the number found on your current unit before purchasing. Related numbers include 93740914, 94580175, 17087653, 17106681, 17111815, 17112404, and 734614.

Ensure the sensor is compatible with your specific vehicle make, model, year, engine size, and transmission type. This sensor is primarily designed for Chevrolet, Daewoo, Opel, Vauxhall, and General Motors vehicles. Different vehicles may have varying specifications, and 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 clockwise rotation. Confirm that the sensor is supplied without cable and has 2 mounting bores.

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 automotive-grade materials. 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. Parts that match the same OE specification used by the vehicle manufacturer ensure proper fit and function.

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 for direct throttle body mounting. Installation requires qualified personnel. 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 (round 3-pin connector)
• 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 warning 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 lifetime warranty on TPS products.
