Product Details

The NTK Automatic Transmission Speed Sensor AU0203 is part of NTK’s technical sensor line, backed by NGK’s automotive experience and OE application knowledge. NTK builds these sensors to meet or exceed OE specifications and subjects them to thermal shock, vibration, and OBD verification testing. This makes AU0203 a practical replacement for vehicles such as the Jeep Compass, Jeep Patriot, Nissan Sentra, Nissan Juke, Nissan Altima, Nissan Rogue, and Dodge Caliber where accurate transmission speed input is required for proper drivability and control.

This part cross-references Standard Ignition SC485 and SC489 for the same application.

What It Helps Address

• Erratic or inaccurate transmission speed signal readings
• Harsh or delayed shifting related to sensor signal loss
• Transmission warning lights triggered by speed sensor faults
• OBD fault codes tied to input or output speed sensor performance
• Driveability concerns caused by inconsistent transmission data

Installation Notes and Tips

Verify connector shape, terminal count, and sensor position before installation. AU0203 is used in both input and output locations depending on the vehicle, so confirm the exact application for your Jeep Compass, Jeep Patriot, Nissan Sentra, Nissan Juke, Nissan Altima, Nissan Rogue, or Dodge Caliber. Inspect the connector for corrosion or damaged terminals and ensure the sensor seats fully before reconnecting the harness.

Quality Assurance

NTK sensors are manufactured to OE-level standards and validated through testing that includes thermal shock, vibration, and OBD verification. The AU0203 reflects NTK’s OE supplier background and technical sensor coverage for import and domestic vehicles.
