Detailed Description
NTK 27020 is an upstream air/fuel ratio sensor engineered for select Fiat 500 and Dodge Dart applications. The specific-fit design helps ensure the correct connector and sensor configuration for the intended vehicle application, while the heated construction supports stable operation once installed. This part cross-references Chrysler 68247753AA for the same application.
As part of NTK's Direct Fit 5-Wire A/F Sensor line, this sensor reflects the brand's focus on OE-style coverage and application-specific replacement parts. NTK uses ceramic sensor technology and manufacturing controls to maintain fit, form, and function across its oxygen sensor range. For buyers searching for a Fiat 500 upstream air/fuel ratio sensor or a Dodge Dart Bank 1 Sensor 1 replacement, NTK 27020 provides a targeted solution.
What It Is Used For
- Replacing a worn or slow-responding upstream air/fuel ratio sensor
- Addressing oxygen sensor fault codes tied to Bank 1 Sensor 1
- Restoring proper air-fuel monitoring for engine management
- Correcting drivability issues caused by inaccurate exhaust feedback
Installation Notes and Tips
Verify the upstream position, Bank 1 Sensor 1 application, and connector match before installation. Confirm thread diameter and harness length against the original sensor to ensure proper fitment on the vehicle. Use the vehicle's service information for removal and installation procedures.
Quality Assurance
NTK states that its oxygen sensors are extensively tested during manufacturing to meet or exceed OE specifications. The brand is part of the NGK family and is recognized as a major original equipment supplier of oxygen sensors.
