NTK AU0053 transmission speed sensor for the 2010-2015 Mazda CX-9 and other vehicles measures the rotational speed of the transmission shafts.
- Input speed goes to the engine or transmission control module as an analog or digital signal
- Signal used for shift points, speedometer operation and transmission diagnostics
- High-strength thermoplastic resists temperature, moisture and chemicals
- Pre-installed o-ring for easier installation and sealing
Quick facts
- Part: NTK AU0053 transmission speed sensor
- Also called: automatic transmission speed sensor
- Fits: 2010-2015 Mazda CX-9 and other vehicles
- Position: Input, output
- Material: High strength thermoplastic
- Condition: New
A lit check engine light, poor or erratic shifting, or a speedometer that works erratically or not at all are reasons to replace an automatic transmission speed sensor. These signs alone do not prove the sensor is at fault, since damaged wiring can cause them too.
Fits
The 2010-2015 Mazda CX-9, the 2006-2013 Mazda 6 and the 2006-2010 Mazda 5 all fit this sensor, as do many other vehicles. It is made to meet or exceed OE fit and function, and its output signal matches OE specifications. A 2010-2015 Mazda CX-9 takes one, and this listing is a single sensor. If your Mazda is not named here, look up its year and model in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right transmission speed sensor for the 2006-2013 Mazda 6?
Yes. NTK AU0053 fits the 2006-2013 Mazda 6, and that car takes one sensor.
Does the NTK AU0053 come with an o-ring?
Yes. NTK AU0053 has a pre-installed o-ring, made to match the OE material and diameter.
What is this transmission speed sensor made of?
This sensor is made of high-strength thermoplastic, which resists temperature, moisture and chemicals.
Can a failing transmission speed sensor cause poor or erratic shifting?
It can be one reason, since the sensor sends input speed to the control module that sets shift points. A shop can read the codes to find the actual cause.
Does the NTK AU0053 interchange with part number 917-648?
Yes. 917-648 is one of the numbers this NTK AU0053 sensor replaces.
