P0122 means the ECU is seeing an abnormally low voltage on throttle position sensor circuit A, typically under 0.2V when it expects 0.5V to 4.5V. Most cars drop into limp mode with capped throttle.

P0122 est un code defaut lie a electrique, classe en gravite moderate. Lorsque le calculateur de ton vehicule detecte cette condition, il enregistre P0122 et allume le voyant moteur.
Si ton vehicule a declenche P0122, tu peux remarquer un ou plusieurs de ces symptomes :
Voici les causes les plus courantes de P0122 :
Non, regle ca immediatement. The ECU usually forces the car into limp mode with reduced power and a locked idle. You can limp home, but hard acceleration and highway merging become risky.

2005-2015 (Mk5/Mk6, 1.4 TSI CAVA/CAXA and 2.0 TDI CBEA/CJAA)
The EPC light comes on with P0122 on these Golfs. On 1.4 TSI engines the throttle body actuator motor brushes wear out around 120,000 to 180,000 km. VW part 03C 133 062 is the common replacement.

2004-2010 (5.4L 3V Triton and 4.6L)
Ford issued TSB 08-7-6 covering electronic throttle body concerns on these trucks, with a revised throttle body part number 9L3Z-9E926-A. The APP (accelerator pedal position) sensor is also a known failure point.

2007-2017 (2.5L 2AR-FE and 3.5L 2GR-FE)
The TPS is integrated into the throttle body (Toyota part 22030-0H030 range) and not sold separately. Toyota's service procedure requires an idle air volume learn after replacement or battery disconnect.
2006-2013 (N52, N54, N55)
BMW uses dual redundant TPS in both the pedal and throttle actuator. P0122 usually pairs with P2135 and drops the car into a restrictive failsafe. Water leaks into the E-box under the cowl are a well-documented cause on E90s.

Uncommon on the Civic, but when it appears the throttle body assembly (Honda part 16400-RNA-A01) is the usual culprit. Honda requires the idle learn procedure (ignition on 2 minutes, then 5 minutes at operating temp) after any throttle work.

Ces codes apparaissent souvent avec P0122 ou indiquent des problemes connexes :
You can move the car short distances, but limp mode caps power and makes merging or overtaking dangerous. Fix it before any highway driving.
It'll clear the light, but if the sensor or wiring is faulty the code returns within minutes of driving. You're masking the problem, not fixing it.
Yes, on almost every drive-by-wire vehicle. Without the relearn the idle will hunt or stall. Most OBD2 apps with bidirectional control can run it in under a minute.
The connector probably wasn't fully seated, or carb cleaner seeped into the TPS. Reseat the plug and let it dry overnight before condemning parts.
Yes. If system voltage drops below about 10V during cranking or under load, the 5V reference can sag and log a low-input code. Load-test the battery before chasing sensors.

The Reduced Engine Power message is the ECU cutting throttle to protect itself. Here is what triggers it, whether you can drive, and what the fix costs.
Clean a sooty throttle body in under an hour for around 15 euros, handle the idle-relearn question honestly, and verify the fix with OBD2 live data.
A flashing check engine light is not the same as a steady one. It almost always means an active misfire that can wreck your catalytic converter in minutes.
