Detailed Description
NTK 24552 is part of the Direct Fit Oxygen Sensor line and is engineered for exact application coverage rather than universal use. It is listed for upstream and downstream positions across select Toyota T100, 4Runner, Pickup, Celica, and Land Cruiser applications, including Federal and California emissions configurations where noted. This part number 24552 is built to match OE-style fit, form, and function for emission control service on Toyota vehicles.
NTK draws on its role as a major original equipment oxygen sensor supplier and uses controlled ceramic technology in sensor production. The result is a sensor line that is extensively tested during manufacturing to meet or exceed OE specifications. This part cross-references Bosch (e.g., 12051, 13198) for the same application.
Common Issues This Part Can Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio readings
- Slow sensor response during closed-loop operation
- Emissions test failures tied to sensor degradation
- Fault codes associated with upstream or downstream oxygen sensor circuits
Installation Notes and Tips
Verify the exact year, model, emissions package, and sensor position before ordering. Fitment includes Toyota T100, 4Runner, Pickup, Celica, and Land Cruiser applications in upstream and downstream locations, with notes for Bank 1 Sensor 1 and Bank 1 Sensor 2 where listed. Confirm connector and thread specifications against the original sensor before installation.
Quality Assurance
NTK states that its oxygen sensors are extensively tested during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. Part number 24552 is backed by NTK's OE-focused sensor engineering and application coverage.
