P0123 means the ECU sees TPS 'A' signal voltage above the upper threshold (typically 4.8V of the 5V reference). The computer ignores the throttle input and falls back to limp mode.

P0123 est un code defaut lie a electrique, classe en gravite moderate. Lorsque le calculateur de ton vehicule detecte cette condition, il enregistre P0123 et allume le voyant moteur.
Si ton vehicule a declenche P0123, tu peux remarquer un ou plusieurs de ces symptomes :
Voici les causes les plus courantes de P0123 :
Non, regle ca immediatement. You can drive short distances, but most vehicles trigger limp mode with reduced throttle response. Sudden power loss is possible, so get it diagnosed before longer trips.

P0123 se comporte differemment selon ton vehicule. Selectionne ta voiture ci-dessous pour des causes propres au modele, les problemes connus et des estimations de couts ajustees :
2004-2015 (Mk5/Mk6)
1.4 TSI (CAXA/CAVD) and 2.0 TDI (CBEA/CJAA) throttle body connectors corrode where the harness routes near the coolant flange. VCDS measuring block 060 typically shows implausible angle-sensor 2 voltage.

2004-2010
5.4L 3V Triton trucks show P0123 with wiper-track wear inside the electronic throttle body. Ford TSB 08-7-6 addresses throttle body replacement for related surging/limp mode complaints.
2001-2011
E46 M54 and E90 N52 often log P0123 when the DK-Motor (throttle actuator) potentiometer starts failing. Genuine throttle bodies run €450-600 for parts alone, aftermarket VDO units around €250.

2AZ-FE and 2GR-FE ETCS-i throttle bodies (22030-28070 / 22030-31010) rarely fail early, but when P0123 appears the internal sensor is usually the culprit. Idle relearn required after cleaning or replacement.

8th/9th gen R18 engines occasionally log P0123 after aftermarket intake installs that disturb the throttle body connector. Honda's idle relearn (throttle body cleaned, KOEO 10 min with A/C off) is required after any TPS work.

Ces codes apparaissent souvent avec P0123 ou indiquent des problemes connexes :
No. It's a hard electrical fault. The MIL might go out after several drive cycles without the fault recurring, but the underlying wiring or sensor issue almost always comes back within minutes.
Yes. It's a stored powertrain code with the MIL on, which is an automatic fail at any OBD2 inspection.
On older cable-throttle cars (mostly pre-2005) the TPS is a bolt-on €40-80 part. On drive-by-wire systems the sensor is integrated into the throttle body and you replace the whole assembly.
The PCM can't trust the throttle signal, so it ignores the pedal and holds the throttle at a fixed low opening (usually 1200-1500 RPM) to prevent unintended acceleration.
Yes, on nearly all drive-by-wire cars. Most brands need a specific idle/throttle relearn procedure (Toyota, Honda, VW, BMW all have their own). Skipping this leaves rough idle even after a good part is fitted.
Un papillon des gaz défaillant donne un ralenti instable, des calages, des à-coups ou le mode dégradé. Son rôle, les symptômes, les codes et le coût.
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.
