Parts for your 2010 Audi Q5-Throttle position sensors

2010 Audi Q5 Throttle Position Sensor (TPS) — What it does and how to look after it

Technical references confirm that the 2010 Audi Q5 does use throttle position sensing. Audi’s ElsaWin workshop manual and ETKA parts catalogue list a throttle valve control module with two integrated angle sensors (G187/G188), and Bosch MED17 engine management uses these dual, redundant tracks. Audi Self‑Study Programme material on the 2.0 TFSI and 3.2 FSI platforms also details electronic throttle control rather than a mechanical cable. So, yes—this Q5 is fitted with throttle position sensors, built into the throttle body.

On a 2010 Q5, the throttle position sensors form part of the electronic throttle body. Their job is to report the exact angle of the throttle plate to the engine control unit, so fuelling, ignition timing, and idle control stay tidy. Two sensors work in tandem for safety: if one reading drifts, the ECU can spot the mismatch and throw a fault to keep the driver safe. You’ll also find an accelerator pedal position sensor, but the throttle body’s own TPS is what tracks the actual plate movement.

When the TPS starts playing up, the Q5 can feel doughy off the line, surge, hunt at idle, or switch into limp mode. The EPC light may appear, and fault codes such as P0121–P0123 or TPS correlation errors can be stored.

Good servicing habits help. While the TPS itself isn’t a consumable, the throttle body and sensors live together, so keeping the bore and plate clean reduces stickiness that can look like a sensor fault. Every 40–60,000 kilometres, it’s smart to:

• Inspect the intake tract for oil mist and sludge, clean the throttle plate with sensor‑safe cleaner (ignition off, battery connected stable).
• Check for vacuum leaks and split PCV hoses that can skew idle control.
• Scan for stored fault codes and live data, compare both TPS tracks for agreement.

If cleaning doesn’t settle the idle or the tracks disagree in live data, replacement is typically the complete throttle body assembly, as the sensors are integral. After refit—or even after a battery disconnect—perform a throttle body adaptation with a scan tool so the ECU relearns end stops. DIYers can sometimes trigger a basic adaptation via ignition‑on procedures, but a proper diagnostic tool is the reliable route.

Use quality parts that match the original spec, tighten the clamp and mounting fasteners to the correct torque, and clear codes before a road test. Done right, the Q5’s throttle response returns to its usual smooth, predictable behaviour.

Popular questions about 2010 Audi Q5 throttle position sensors

Where is the throttle position sensor on a 2010 Audi Q5?
It’s integrated into the electronic throttle body on the intake manifold—there isn’t a separate bolt‑on TPS. The module contains two angle sensors (redundant tracks) that the ECU monitors.

What are common symptoms of a failing TPS on this model?
Drivers may notice an EPC light, limp mode, unstable idle, flat spots on tip‑in, or surging. Scan tools often show correlation faults or out‑of‑range signals from one of the two tracks.

Can the TPS be cleaned, or does the whole throttle body need replacing?
Cleaning can help if the throttle plate is sticking, but if the sensor tracks are faulty or readings don’t correlate, the fix is usually replacing the complete throttle body, followed by an adaptation procedure.
