What is the P0725 error code? What are the causes for the P0725 error code? How can you fix the P0725 error code? What does Engine Speed Input Circuit Failure mean ?….?

It is difficult to diagnose and repair some problems in vehicles. Automakers have made it easier. Nearly all modern cars have an onboard diagnostic system you can use to diagnose the problem. You will need to have some technical knowledge in order to use the system. The OBD2 diagnostic tool will give you error code P0725 if there is an issue with your vehicle’s sensor. This article will help you to fix the problem.

 

What is the P0725 fault code?

The powertrain control module (or PCM) is a component of your vehicle. This module controls all components of your engine and transmission. To do its job, the PCM relies on a variety of sensors. P0725 is an error code that indicates a problem in one of these sensors. There are three types of problem sensors:

  • – Engine speed sensor
  • – Transmission speed sensor
  • Speed sensor

These sensors are called different things by different sources, but they all mean the exact same thing. Based on engine RPM, the speed sensor informs the PCM when it is time to shift gears. A P0725 code will be issued if the speed sensor does not send a signal to the PCM, if the signal doesn’t increase steadily, or if there is an abnormal or irregular pattern, the signal will not be received.

 

What are the symptoms for P0725

The PCM can’t measure your vehicle’s speed if the speed sensor is damaged. This can lead to many system malfunctions. These symptoms could include:

  • – Illumination for the engine fault lamp
  • Transmission cannot shift gears
  • – Delay or erratic gear change
  • – Defective mileage indicator
  • – Defective tachometer
  • – PCM may put the tool into protection mode (Limp Mod)
  • – Engine misfires or stalling

 

What causes P0725 Fault

  • – Sensor for engine speed input fault
  • – Sensor for defective transmission output speed
  • – Broken, loose or worn connectors
  • – Damage to or short circuit in cables
  • – Pressure related or valve body issues
  • – Transmission oil that is low or not at all clean
  • – Defective shift solenoids
  • – Very rare PCM defects

 

How Serious Is the P0725 Fault Coding?

Driving safety is at risk from all of the symptoms mentioned above. It can also cause damage to the transmission, which can be one of most expensive parts of a vehicle. You can easily replace the sensor. This error code is important and should be addressed immediately to prevent further damage to your vehicle.

 

How do you fix the P0725 fault?

You must first determine what caused the malfunction. The fault code could be caused by a defective circuit or sensor. This error code can be sent if the sensor has been damaged. The sensor may also have metal deposits. The problem could be both electrical and mechanical. Even if the sensor works, the circuit or connectors can be damaged and the PCM won’t receive any signals. There is no problem with the electrical supply if the PCM receives a signal from the sensor. You should pay attention to the transmission if there is no fault with the circuitry or sensor.

  • – Replace the engine speed input sensors
  • – Change the transmission output speed sensor
  • Repair or replace damaged connectors and cables
  • – Replace solenoids
  • – Change transmission fluid or filter
  • – Repair transmission fluid leaks
