Error Code P0715: What It Means & What To Do?

<<See All OBD Codes

When will your vehicle’s input speed sensor malfunction? Do you what are the causes of these trouble codes and how this error codes occur? P0715 error code gets stored in your vehicle if the powertrain control module detects a malfunctioning in the input speed sensor. You will find this sensor near the rear of the torque converter on threaded directly into the transmission case.

You will see specially designed grooves on the input shafts. The input shaft completes the electromagnetic circuit by passing in close proximity to the end sensor. As the grooves pass by the sensor, the circuit is intermittent and electronic pattern is formed. This pattern is received as a waveform pattern by the PCM that it further understands as transmission input speed. If the actual input speed flops to agree with the desired input speed, a code will be stored and a malfunction lamp may be lit.

What causes this problem with the Input/Turbine Speed Sensor A Circuit Malfunction?

• Defective transmission speed sensor.
• Damaged or damaged speed sensor wiring.
• Damaged speed sensor electrical connection.
• Defective shift solenoids.
• Broken transmission valve body.
• Murky transmission fluid.
• Corrupt transmission torque converter.
• PCM faulty.

1. Transmission Speed Sensor - If you find this component to be faulty or broken replace or change them as desired.
2. Input Speed Sensor - The error code will be stored in your vehicle if the sensor malfunctions. Replace or fix the sensors.
3. Output Speed Sensor - The output speed sensor should function properly. Else you will find the P0715 error code in your vehicle.
4. Shift Solenoids - A lack of pressure indicates a faulty shift solenoid. Change them immediately
5. Transmission Fluid - Are you looking for this replacement part? Get them easily from Parts Avatar
6. Automatic Transmission Valve Body - Replacing this defective component can help you to get rid of the error codes stored.
7. Torque Converter - If this component overheats then it is more likely to be damaged. Fix them immediately.
8. Engine Coolant Temperature Sensor - Check for any leaks in the component. If so clean them properly.
9. Powertrain Control Module - A faulty or defective PCM needs immediate replacement in order to avoid malfunction in the system.
10. Multimeter - Is your Multimeter damaged? Looking for the right part? Get them at Parts Avatar.

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0715 here:

Common Symptoms

• Irregular transmission shift points.
• Faulty transmission shift.
• Reduced fuel efficiency.
• Speedometer variation.
• Absence of speedometer process.
• The engine may stop.
• Engine Light is bright.

Want to correct the Trouble Code P0715? Read these points mentioned below:

• Check for the technical service bulletin for your vehicle. Your issue can be known and can be fixed by the manufacturer which saves time and money during diagnosis process.
• In order to diagnose the P0715 error code you will need a diagnostic scanner, a digital volt/ohmmeter (DVOM), a system wiring diagram, and an oscilloscope.
• Technicians will usually begin by inspecting the wires and connectors. Replace the corroded, burnt or separated parts as needed. Test the battery and check the cables and its end. Clean the corrosions and preserve the battery terminals.
• Recover all stored codes by connecting a scanner to the diagnostic port. Store the codes for further reference. Also note down the freeze frame data.
• If both the input and output sensor codes are present, use the scanner data to define which circuit is malfunctioning. Narrow it to related data for more response
• As you remove sensors, check for debris and remove them in the magnetic contacts. Test each sensor with a DVOM by following specifications of the manufacturer. Replace the parts if they fail to comply.
• Separate the controllers before you test the resistance and continuity with DVOM. If you fail, the controller will be damaged. See for open wires or shorted circuit and replace as needed. If every component works properly, your PCM will be faulty.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0715 code to be stored:

Visually inspect the input speed sensor in order to find the condition of the wires. Replace, if you find any damages. The mechanic will also check the ground wire to the sensor to see if there is fault with the wires or sensors. If it is damaged, the mechanic will replace them and test drive the vehicle. If this does not fix, then there will be a problem in the transmission.

Common Mistakes When Diagnosing The P0715 Code

Input speed sensor wiring can be injured from transmission fluid leaks that are not fixed after replacing the sensor wires. The sensor will fail again if this is done.
