What It Helps Resolve

• Erratic or missing transmission input speed signal
• Transmission shifting concerns related to speed sensor data
• Check engine light conditions tied to transmission speed sensor faults
• Harsh, delayed, or inconsistent shifting caused by sensor failure
• Diagnostic trouble codes associated with input speed sensor performance

Installation Notes and Tips

Verify the connector style, terminal count, and harness length before installation. This sensor uses a rectangular male connector with two blade terminals and includes a wiring harness. Confirm the vehicle’s transmission input sensor location and match the application by year, make, model, and position before replacing the original part.

For best results, inspect the connector, wiring, and surrounding transmission components for corrosion, damage, or fluid intrusion during service. Clear diagnostic codes after installation and confirm proper transmission operation with a road test.

Quality Assurance

NTK sensors are developed from OE experience and tested under thermal shock, vibration, and OBD verification conditions. The AU0186 is manufactured to meet or exceed OE specifications for the listed applications.
