Code P1134 Suzuki Description

The P1134 Suzuki code refers to an issue with the HO2S11 (Heated Oxygen Sensor 1 Bank 1 Sensor 1) transition ratio. The oxygen sensor is a crucial component of the vehicle's emissions system, responsible for monitoring the oxygen levels in the exhaust gases. The transition ratio indicates the rate at which the oxygen sensor switches between rich and lean air-fuel mixtures. If the transition ratio is not within the expected parameters, it can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
