Keep your automatic transmission reporting accurate temperature data with the Standard Ignition Automatic Transmission Fluid Temperature Sensor, MPN TX252. It fits as a direct-fit replacement for the listed applications: 2007-2015 Acura MDX (All), 2007-2012 Acura RDX (All), 2009 Acura TL (All), 2011-2014 Acura TL (All), and 2010-2013 Acura ZDX (All) — all engines.
This sensor monitors the temperature of the automatic transmission fluid and signals that reading to the transmission control module, which uses it to manage shift timing and torque converter operation and to help guard the transmission against overheating. When the original sensor sends a false or erratic reading, shift behavior can suffer, so a properly functioning replacement provides accurate temperature input to the controller.
- Function: Measures automatic transmission fluid temperature and reports it to the control module.
- Role: Helps the control module adjust shift timing and torque converter lockup based on fluid temperature.
- Fitment: Direct-fit replacement for the listed Acura applications; each application uses one sensor.
Signs the sensor may need replacing include erratic or harsh shifting, a transmission temperature warning, or a temperature-related trouble code — diagnose the underlying cause before replacing, since these symptoms can have other sources.
Manufacturer part number TX252.
Frequently Asked Questions
What does the TX252 sensor do?
It measures the temperature of the automatic transmission fluid and reports that reading to the transmission control module, which uses it to manage shift timing and torque converter operation.
Which vehicles does this sensor fit?
It is a direct-fit replacement for the 2007-2015 Acura MDX, 2007-2012 Acura RDX, 2009 Acura TL, 2011-2014 Acura TL, and 2010-2013 Acura ZDX (all engines). See the Buyer's Guide tab to confirm your vehicle.
What are signs this sensor may need replacing?
Possible signs include erratic or harsh shifting, a transmission temperature warning, or a temperature-related trouble code. Diagnose the cause first, as these symptoms can have other sources.
Does this sensor read transmission fluid or coolant temperature?
It reads automatic transmission fluid temperature — not coolant. The reading helps the control module respond to how hot the transmission fluid is running.
How many sensors do I need?
It is sold individually, and each listed application uses one sensor per the fitment data.
