Toyota 2-Wire Oxygen Sensor 234-2052 Replaces 234-2051 Economy Replacement

KLP oxygen sensor 234-2052 can directly replace original 234-2052 and is also compatible with 234-2051 and 234-2050 as an economical replacement. Monitors oxygen in exhaust and feeds ECU to adjust air-fuel ratio, improving engine efficiency. Fits Toyota Camry, Corolla, RAV4 and other 2.0–2.4L after-2000 models. After installation, it effectively resolves high fuel consumption, rough idle, and weak acceleration, and clears engine warning lights. If power drops or fuel consumption abnormal, replace promptly.
