Parts for your 2013 Audi Q5-Throttle position sensors

2013 Audi Q5 throttle position sensors

Based on Audi technical literature — including Audi Self‑Study Programmes for the 2.0 TFSI (EA888), 3.0 TFSI and TDI engines, plus the Q5 (8R) factory repair manuals for Motronic/EDC electronic throttle control — the 2013 Audi Q5 does use throttle position sensors. In fact, there are typically two throttle valve position sensors integrated into the throttle body (often referenced as G187 and G188) for redundancy, and separate accelerator pedal position sensors in the pedal module. So yes, throttle position sensing is absolutely relevant on this model.

On a 2013 Q5, the throttle position sensors (TPS) live inside the electronic throttle body. Their job is to tell the engine control unit exactly how far the throttle plate is opened, so fuelling, ignition and boost (where applicable) can be trimmed precisely. With drive‑by‑wire, the pedal asks for torque, and the ECU compares the pedal sensors to the throttle valve sensors to make sure everything lines up. That’s why there are usually two tracks inside the TPS — it’s a safety check that keeps the car out of trouble if one track goes out of range.

There’s no fixed service interval for the TPS, they’re monitored constantly by the ECU. During routine servicing, it’s smart to:

• Scan for fault codes like P0121, P0122, P0123, P2135 and related EPC/limp‑home events.
• Inspect wiring/connectors for moisture, corrosion, or chafing, especially near the throttle body.
• Clean the throttle body if there’s carbon build‑up affecting idle stability, avoid flooding the shaft or sensors with solvent.
• Perform throttle adaptation/basic settings with a proper scan tool after cleaning or battery replacement.

Common signs the TPS/throttle body needs attention include erratic idle, hesitation off the line, cruise control dropping out, poor fuel economy, or the EPC light coming on. If faults persist after cleaning and wiring checks, the fix is usually to replace the throttle body assembly, as the sensors are integrated and not serviceable separately on most VAG units. After replacement, a basic settings/adaptation is required so the ECU learns the new throttle end‑stops. Quality parts and a correct sealing gasket are essential, and any mounting fasteners should be tightened to workshop specs. Given the Q5’s mix of petrol and diesel variants, procedures vary slightly, but the general approach is the same across the range. A technician familiar with Audi’s electronic throttle systems will get it sorted quickly and keep the car driving smoothly.

Popular questions about 2013 Audi Q5 throttle position sensors

Does a 2013 Audi Q5 actually have a throttle position sensor?
Yes. Audi’s electronic throttle uses dual throttle valve position sensors inside the throttle body, plus redundant accelerator pedal sensors. This setup is documented across Audi Self‑Study Programmes and the 8R Q5 factory repair manuals.

What are the symptoms of a failing TPS on a 2013 Q5?
Look for an EPC light, inconsistent idle, flat spots on acceleration, cruise control cutting out, or limp‑mode behaviour. Scan for codes like P0121–P0123 or P2135. Sometimes a throttle body clean and an adaptation will restore proper operation, otherwise the throttle body is replaced.

Can the TPS be cleaned or adjusted, or does it need replacement?
The sensors are integrated and not adjustable. You can clean the throttle bore and plate carefully and then run a basic settings/adaptation. If faults persist or tracks are faulty, replace the throttle body assembly and carry out adaptation with a scan tool.
