P0716 code — how to fix error fast

The OBD2 code P0716 is related to your car’s transmission system and if you don’t repair it on time, it could lead to some devastating consequences for your car. We know it sounds a bit dramatic, but the truth is – most drivers tend to overlook the true P0716 code meaning so they just move on with erasing the code.

While this is possible even without fixing the underlying issue behind it, doing so will only postpone the costly repairs waiting for you down the road. So, we wanted to have you prepared to tackle the code with this comprehensive guide on P0716 code’s causes, diagnostic methods you can apply, and the best ways of fixing the code.

What does the P0716 code mean?

The P0716 code is a transmission input speed sensor circuit range/performance error. This means that the powertrain control module (PCM) has detected a discrepancy between the transmission input speed sensor’s actual reading and the expected reading. The input speed sensor is responsible for determining the speed of the transmission’s input shaft and sends this information to the PCM, which uses it to regulate various transmission functions.

It’s important to understand this code because it can cause several issues, including the transmission not shifting properly, the engine stalling or hesitating, and reduced fuel efficiency. In addition, ignoring the code can lead to more serious transmission problems and costly repairs down the line.

What causes the P0716 code?

You can get to the bottom of the code only by figuring out what’s causing it in the first place, so it’s also important to consider the main symptoms. Some common symptoms of the P0716 code include harsh shifting, delayed shifting, transmission slippage, and a decrease in fuel economy. Still, to further diagnose the issue, you’ll need to know more about the most possible causes of the code:

Faulty input speed sensor

The most likely culprit is a faulty sensor itself. Over time, these sensors can wear out or become damaged, which can cause them to send incorrect signals to the vehicle’s computer

Wiring issues

Another common cause of P0716 is a problem with the wiring that connects the input speed sensor to the vehicle’s computer. If there is a break or short in the wiring, or if the connections are loose or corroded, it can cause inaccurate readings from the sensor.

Problems with the TCM

In some cases, P0716 may be triggered by a failure in the transmission control module (TCM). This module is responsible for receiving signals from various sensors in the transmission and using that information to control its operation. If the TCM fails, it can cause a number of issues, including incorrect readings from the input speed sensor.

Other transmission problems

Finally, P0716 may be caused by actual problems with the transmission itself. If there is damage or wear to the internal components of the transmission, it can cause issues with the input speed sensor circuit.

Which car models does the P0716 code affect the most?

The P0716 code can appear in a variety of car models, but some models are more prone to it than others. We wanted to know a bit more about these models, so we scanned the reports, driver complaints, and common reasons for recalls of the components that may have caused the code in these cars:

• Honda Accord: The Honda Accord is one of the most common vehicles to experience issues with P0716. This is particularly true for models manufactured between 1998 and 2002.
• Ford Focus: Another make and model that is frequently associated with P0716 is the Ford Focus. This issue seems to be most prevalent in cars manufactured between 2000 and 2005.
• Nissan Altima: The Nissan Altima is another vehicle that can be affected by P0716. This code is often triggered in models manufactured between 2002 and 2006.
• Toyota Camry: Finally, the Toyota Camry is a popular car that can also experience issues with the input speed sensor circuit. This problem is most common in models manufactured between 1997 and 2001.

How to diagnose the P0716 code

The first step in diagnosing the P0716 code is to use a diagnostic scanner to read the code and any other related codes that may have appeared. Once the code has been identified, you can proceed with one of these testing methods to determine the root cause of the problem:

Visual inspection

The first step in diagnosing P0716 is often a visual inspection of the input speed sensor and its wiring. You can look for any signs of damage, wear, or corrosion that could be affecting the sensor’s performance.

Looking for related codes

In some cases, P0716 may be accompanied by other codes related to the transmission. You may check for these additional codes to get a better sense of what’s causing the issue.

Testing the sensor

If the visual inspection and scan tool test doesn’t reveal any obvious issues, you can test the input speed sensor itself using a multimeter or oscilloscope. This can help determine whether or not the sensor is functioning properly.

Looking for faulty wiring or connections

Finally, you may check the wiring and connectors that connect the input speed sensor to the vehicle’s computer. This can include checking for breaks in the wiring, loose connections, or corrosion that could be affecting signal quality.

How to fix the P0716 code

Fixing the P0716 code will depend on the cause of the problem. Here are some potential fixes for each cause, as well as some of the main pieces of information on how much it may cost to fix such an issue:

Replace the input speed sensor

If the input speed sensor is faulty, replacing it is often the easiest way to fix P0716. This typically involves removing and replacing the old sensor with a new one, which could set you back between $150 and $300 on average.

Repairing the wiring or connections

If there is damage or wear to the wiring or connectors that connect the input speed sensor to the vehicle’s computer, repairing or replacing them can help restore proper signal quality and fix P0716. This one fits into the category of more affordable fixes with average costs of around $100 to $200.

Replacing the transmission control module

In some cases, P0716 may be caused by a failure in the transmission control module (TCM). If this is the case, replacing the TCM may be necessary to fix the issue. This one can be more expensive and it often ranges between $500 and $1000.

How to prevent the P0716 code

Proper maintenance of the transmission system can help prevent the P0716 code from appearing. Routine maintenance, such as changing the transmission fluid and filter, can help keep the system in good condition. Additionally, these actions can help reduce the chances of the code ever emerging again:

• Driving less aggressive
• Keeping up with the regular maintenance schedule
• Check the TCM’s operation and the input speed sensor

If you can avoid aggressive driving and keep up with regular inspections, it can help catch any issues before they become major problems and cause the code P0716 again.

Our take

In conclusion, the P0716 code is a common transmission error that can cause several issues if ignored. We hope that this guide will aid you in understanding the causes, symptoms, and potential fixes to ensure that your vehicle stays in top condition and avoid costly repairs down the line.f
