P2119 — also written P2119, P 2119, 2119 — is the OBD-II code for throttle actuator control throttle body range/performance. Same code, same fix: this page covers every spelling of it.
P2119 is a engine fault code, typically costing £90–£500 to put right in a UK garage.
What causes P2119?
- Carbon build-up around the throttle plate
- Worn throttle body return spring
- Failed position sensor inside the body
- Adaptations never reset after cleaning
How P2119 is fixed
- Clean the throttle body properly with the correct cleaner
- Carry out the throttle adaptation procedure — cleaning without it often leaves the fault
- Replace the throttle body if the plate is worn
P2119 repair cost in the UK
Most P2119 repairs land between £90–£500 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
