P0716 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Do you have any idea or knowledge about the P0716 error code? How does it occur? This OBD II error codes indicates that the computer of the car has received an input signal from the engine speed sensor which is wrong in some or other way. Without exact information, the computer will not be able to create the appropriate shifting strategy for the transmission.

If the automatic transmission has to shift properly, the computer of the car has to know the engine speed of the vehicle. If the input signal is irregular or wrong from the input speed sensor, then the computer will lack information that is crucial for shifting rightly for current conditions. If the input speed changes drastically, or surpasses the output speed, then the power control module will set the P0716 error code.

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

• The input speed sensor is faulty.
• The output speed sensor is faulty.
• The wiring harness of the sensor is defective.
• The input or output speed sensor has corroded connections.
• The transmission shift solenoid is defective.
• The engine coolant temperature sensor is faulty.
• The transmission fluid is less.
• The transmission fluid is dirty or contaminated which does not flow properly.
• As a very rare case, the powertrain control module is faulty.

1. Speed Sensor - Visually check for defectives or damages in the speed sensor. If you come across any damages in this component, get the right one from Parts Avatar at cheap prices online.
2. Engine Speed Controller - The speed controller controls the speed of your engine. If it is defective, it will be difficult to control. Replace with a component.
3. PCM - One common error in most of the vehicle is the faulty/ defective/ broken powertrain control module which causes the P0716 error code to be stored in your vehicle. Replace the faulty component as desired.
4. Automatic Transmission Fluid - If you are looking for the right replacement part, grab them at Parts Avatar at the best prices online.
5. Engine Coolant Temperature Sensor - Check for any leaks in the component. If so clean them properly.
6. Multimeter - Having a damaged Multimeter? Looking for the right part? Get them at Parts Avatar.

It is essential 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 P0716 here:

Common Symptoms

• The engine becomes idle when it stops.
• Misfiring of the engine.
• The shifting is harsh.
• Shifting failure.
• Stalling of the engine.
• Hesitation to start.
• Fluctuations in the speedometer.
• Inoperable speedometer.
• Check engine light is too bright.

Here are some ways with the help of which you will be able to correct the OBD Code P0716

• Replacement of the faulty input speed sensor.
• Replacement of the faulty output speed sensor.
• Rebuilding a faulty transmission that is indicated by contamination or fining in the transmission fluid.
• Fixing or replacement of the faulty wires.
• Fixing the connections that are corroded.
• Changing the faulty circuits.

Here are some steps which you should follow in order to diagnose this fault code:

• Initially, the technician will connect an OBD II scan tool to the car and check for code or error codes. These codes will be cleared later and the technician will test drive the vehicle to see if the codes are reset and if the mechanic is able to duplicate the symptoms as mentioned by the driver.
• Secondly, the mechanic will also check for the level and condition of the transmission fluid so as to rule out the less fluid level or the contamination of fluid as the culprit.
• If the code is reset, then the mechanic will have to check for the ground signals or the reference voltage at the position of the input speed sensor. If it is open, then the mechanic will have to check for the continuity and repairs and he has to replace if there are any damaged wires or circuits. If there are no openings then the mechanic will continue to test the wires and circuits as well, he will check all its related sensors and solenoids in order to define the underlying cause.

Common mistakes when diagnosing the P0716 code

One of the common mistakes here is the replacement of the speed sensor which may not be the actual problem. A full diagnosis has to be carried out in order to rule out all the other possible causes, which includes the contamination of the transmission fluid, damage to the wire harness and much more. As a first step, the trouble code has to be troubleshot, and the corresponding codes in the order of occurrence.
