P0132O2 Sensor Circuit High Voltage (Bank 1, Sensor 1)

The upstream oxygen sensor on bank 1 is showing a steady high voltage, which the computer interprets as a constantly rich exhaust (too little oxygen) or a circuit fault. In response the computer may cut back fuel, which can hurt performance and economy. The real cause can be the sensor, its wiring, or an actual rich-running engine.

Ամենատարածված պատճառներն են՝ Failed upstream oxygen sensor, Short to voltage in the sensor signal wiring, Contaminated sensor (coolant, oil, silicone, leaded fuel), Genuine rich condition (leaking injector, high fuel pressure), Connector corrosion or short between wires, Engine control module fault (rare)։

Սովորաբար անվտանգ է կարճ տարածությունների վրա վարել, սակայն շուտով ստուգել տվեք։

Short trips are generally fine, but a persistently rich condition can foul spark plugs and damage the catalytic converter over time, so fix it soon. Have the sensor and wiring checked, and rule out a leaking injector or high fuel pressure before replacing the sensor.
