Code P1D73 Acura Description
The P1D73 code for Acura vehicles indicates a Traction Motor Temperature Sensor Range/Performance Problem High. This code is typically associated with electric or hybrid vehicles that utilize traction motors for propulsion. The traction motor temperature sensor is responsible for monitoring the temperature of the motor to ensure it operates within a safe range. When the sensor detects that the temperature is too high or outside the normal operating range, it triggers the P1D73 diagnostic trouble code (DTC).
Common Causes of P1D73 Acura
- Faulty traction motor temperature sensor
- High ambient temperatures causing the motor to operate at higher temperatures
- Restricted airflow to the motor due to a clogged air filter or debris
- Electrical issues such as a short circuit or wiring damage
- Software or calibration issues with the traction motor temperature sensor system
Symptoms of P1D73 Acura
- Reduced power and acceleration
- Engine overheating warning light illuminated on the dashboard
- Reduced fuel efficiency
- Limp mode activation, limiting vehicle speed and performance
- Unusual noises coming from the traction motor
How to Fix P1D73 Acura
- Diagnose the issue by using a diagnostic scan tool to retrieve the specific fault code and determine the underlying cause of the problem.
- Inspect the traction motor temperature sensor and wiring for any signs of damage or corrosion. Replace the sensor if necessary.
- Check the cooling system for proper operation and ensure there are no obstructions blocking airflow to the motor.
- Clear the fault code from the vehicle's computer system and perform a test drive to ensure the issue has been resolved.
- If the problem persists, consult with a professional mechanic or dealership for further diagnosis and repair.
Cost to Fix P1D73 Acura
The typical repair costs for addressing a Traction Motor Temperature Sensor Range/Performance Problem High code can vary depending on the specific cause of the issue and the labor rates in your area.

What are the common symptoms of code P1D73 in an Acura?
Symptoms may include the Check Engine Light turning on, reduced engine or hybrid system performance, and possible activation of limp mode.
What causes the P1D73 code to appear in an Acura?
The code can be triggered by a faulty traction motor temperature sensor, damaged wiring or connectors, overheating of the motor, or an issue with the powertrain control module (PCM).
Can I drive my Acura with the P1D73 code?
It is not recommended to drive with this code active, as it may indicate overheating or potential damage to the traction motor, which could lead to further issues.
How is the P1D73 code diagnosed?
A technician will use a scan tool to confirm the code, inspect the traction motor temperature sensor and its wiring, and perform tests to verify the sensor's functionality and temperature readings.
What repairs can fix the P1D73 code on an Acura?
Repairs may involve replacing the traction motor temperature sensor, repairing or replacing damaged wiring or connectors, or addressing overheating issues in the traction motor.
How much does it cost to fix the P1D73 code on an Acura?
Repair costs can vary, but replacing the traction motor temperature sensor typically ranges from $150 to $300, depending on labor costs and parts availability.
Can a software update resolve the P1D73 code?
In some cases, a software update to the powertrain control module (PCM) may address sensor calibration or system performance issues, but this depends on the specific vehicle and situation.
What happens if the P1D73 code is ignored?
Ignoring this code can lead to further damage to the traction motor, reduced performance, and potentially expensive repairs if overheating or electrical issues persist.
Is the traction motor temperature sensor the same as a coolant temperature sensor?
No, the traction motor temperature sensor specifically monitors the temperature of the hybrid or electric motor, whereas a coolant temperature sensor monitors engine coolant temperature.
