P2234 Suzuki Code - HO2S Signal Circuit Shorted to Heater Circuit Bank 2 Sensor 1
Quick Answer
The Engine Control Module (ECM) supplies a voltage near 450 mV between the Heated Oxygen Sensor (HO2S) signal circuit and the low reference circuit. Common causes include Faulty Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1, Heated Oxygen Sensor Bank 2 Sensor 1 harness is open or shorted, Heated Oxygen Sensor Bank 2 Sensor 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
