P0133 — O2 sensor: slow response (bank 1 sensor 1)

Severity: Attenzione Can you drive? Sì, no known limitation Produttore: Tutti makes (OBD-II standard)
MeaningThe sensor ahead di the catalyst reacts too slowly a mixture changes. It is not broken: it is aged, and the ECU can No longer trim with the RICHIESTO precision.
FamilyPowertrain (P)

Typical symptoms

Higher fuel consumption
Slightly rough idle
Motore Attenzione light on
Problems alle the emissions test

Common causes

Sensor aged by mileage oppure contamination
Exhaust leak upstream di the sensor
Burnt oil oppure coolant poisoning the sensor
Weak sensor heater
Additives oppure poor quality fuel

What a do

The upstream sensor is a wear Voce: replacement after 120-150,000 km is Normale. Prima check for exhaust leaks upstream, otherwise the new sensor will read just as falsely as the old one.
