Code P174E Description
The P174E diagnostic trouble code refers to the Output Shaft Speed / ABS Wheel Speed Correlation. This code indicates a discrepancy between the speed of the output shaft of the transmission and the speed of the wheel sensors in the anti-lock braking system (ABS). In a properly functioning vehicle, these speeds should be closely correlated to ensure smooth operation and accurate transmission of power to the wheels.
Common Causes of P174E
- Faulty output speed sensor
- Malfunctioning wheel speed sensors
- Wiring or connection issues between sensors and control modules
- ABS module failure
- Transmission control module malfunction
Symptoms of P174E
- Erratic shifting or difficulty changing gears
- ABS warning light illuminated on the dashboard
- Loss of traction control functionality
- Reduced fuel efficiency
- Transmission slipping or jerking
How to Fix P174E
- Diagnose the issue by connecting a diagnostic scanner to read the trouble codes and perform tests on the output shaft and wheel speed sensors.
- Inspect the wiring and connections for any damage or corrosion, repairing or replacing as needed.
- Replace the faulty output speed sensor or wheel speed sensors if they are found to be defective.
- Test the ABS and transmission control modules for proper function and replace if necessary.
- Clear the trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P174E
The cost of repairing a P174E code can vary depending on the specific cause of the issue and the labor rates of the auto repair shop. Typically, the cost of parts such as sensors or modules can range from $100 to $500, while labor costs may be between $200 and $500. Overall, the total repair cost for this issue could be anywhere from $300 to $1000. It's important to note that these are rough estimates, and actual costs may differ based on the location, make and model of the vehicle, and the expertise of the technician.
