A throttle position sensor (TPS) is a crucial engine-management component. It measures the angle or position of your vehicle’s throttle valve and sends this data to the engine control unit (ECU). This allows the ECU to manage fuel injection, ignition timing, and air-fuel mixture with precision—directly influencing engine performance, throttle responsiveness, and fuel efficiency.
At Aus Auto Store, we offer a curated selection of high-quality TPS units—from OEM-standard replacements to aftermarket upgrades—compatible with a wide range of vehicles. Whether you’re fixing erratic throttle behavior or optimizing performance, we’ve got the sensor you need.
Why Throttle Position Sensors Matter
-
Ensure proper throttle response and air-fuel ratio.
-
Help prevent engine surges, stalling, or hesitation.
-
Support smooth acceleration and idle stability.
-
Improve fuel economy by ensuring efficient combustion.
-
Enable precise transmission shifting in automatic vehicles.
A faulty TPS can confuse the ECU, leading to inconsistent power delivery, loss of performance, or increased fuel consumption.
Signs Your Throttle Position Sensor May Be Failing
If your car is experiencing any of the following, the TPS may need inspection or replacement:
-
Engine surges or stalls
-
Jerky or hesitant acceleration
-
Unstable or fluctuating idle RPM
-
Reduced power or slow throttle response
-
Transmission shifting issues (in automatic gearboxes)
-
Check engine light triggered by throttle-related codes
These symptoms often worsen over time, so early detection and replacement are essential.
Types of Throttle Position Sensors We Offer
At Aus Auto Store, our TPS collection includes:
-
Potentiometer-type sensors: Common in many vehicles. Use mechanical contact and variable resistance to track throttle movement.
-
Hall-effect / non-contact sensors: Found in more modern vehicles. These offer improved durability and accuracy by eliminating mechanical wear.
-
OEM-standard units: Designed to match original manufacturer specs for reliability.
-
Performance sensors: Engineered for improved throttle sensitivity and responsiveness, ideal for tuned vehicles or performance builds.
Each sensor is tested for quality, fitment, and compatibility.
Choosing the Right TPS for Your Vehicle
Before purchasing, confirm:
-
Your vehicle’s exact make, model, and engine code
-
The type of throttle system (mechanical vs electronic)
-
Whether an OEM-spec or upgraded performance sensor is more appropriate
-
If other related components (wiring, throttle body) might also need attention
Use our site filters to match the right TPS for your car. Each product listing includes detailed compatibility and specifications.
FAQs – Throttle Position Sensors
What does a throttle position sensor do?
It monitors the position of the throttle valve and sends this information to the ECU, which uses it to regulate fuel and ignition for optimal performance.
Can a bad TPS cause my car to stall or surge?
Yes. A malfunctioning TPS can send incorrect signals to the ECU, causing surging, stalling, or jerky acceleration.
How do I know if my TPS needs replacing?
Look for symptoms like rough idle, poor throttle response, engine surging, or check-engine lights related to throttle or sensor codes.
Is it easy to replace a TPS?
In most cases, yes. It’s usually a bolt-on part located on the throttle body. However, accurate fitment and proper calibration are essential.
