By Ezra Lane You're encountering a P0717 Nissan error code, which indicates a problem with the input/turbine speed sensor circuit signaling, essential for accurate gear shifting. This malfunction typically arises from a faulty sensor, damaged wiring, or transmission control module (TCM) problems. These issues can lead to erratic or delayed shifting, potentially worsening if not addressed promptly. To diagnose, you'll need tools like an OBD-II scanner and a multimeter to test sensor resistance and connectivity. Replacing the defective sensor is often necessary, followed by clearing the fault codes from your vehicle's computer system. Addressing this error can prevent further transmission damage, ensuring safer driving conditions. By understanding this issue, you'll be better equipped to manage your vehicle's health.
P0717 Nissan Code Meaning
Nissan's P0717 code signals a turbine revolution sensor circuit issue, disrupting transmission data to the ECM.
Causes include a faulty sensor, damaged wiring, or TCM issues.
Promptly addressing this prevents further transmission complications and ensures smooth gear shifts.
Error Code P0717 Symptoms
When the P0717 code lights up on your Nissan, you'll see the check engine light first. This signals an issue with the turbine revolution sensor circuit. But that's just the start of possible problems while driving.
Here's what you might notice:
- Erratic Shifting: The transmission may shift randomly. It might change gears too early or too late. This can make your drive feel uneven or sluggish.
- Delayed Shifting: When you press the gas, the car may not speed up right away. This can make it slow to react, especially when you need to move quickly.
- Transmission Slipping: You might hear the engine revving, but the car doesn't move as it should. This can reduce power and fuel efficiency, as the engine works harder but produces less result.
These signs can affect how you drive and how well your vehicle performs over time.
Causes of Nissan P0717 Fault Code
Many things can cause the P0717 error in your Nissan. Knowing why helps fix the problem. Here's a simple breakdown:
1. Bad Turbine Sensor: This sensor checks how fast parts inside the car move. If it's not working, the car's computer can't shift gears right, causing the P0717 error.
2. Broken Wires or Connectors: Wires and connectors send signals from the sensor to the car's computer. If they're damaged, signals won't get through, which can trigger the error code.
Check these parts often to catch any problems.
3. Rust or Dirt: The sensor can get rusty or dirty over time. When this happens, it can't send clear signals to the car's computer, which leads to the error code.
Fixing these issues helps your Nissan run smoothly without transmission problems.
Tools Needed to Diagnose
To figure out what's causing the P0717 error code in your Nissan, you'll need a few tools. Having the right ones can make the job easier and more accurate.
Here's what you need:
- OBD-II Scanner: This device helps you read and clear error codes from the engine's computer. Use it to check if the P0717 code still shows up after fixing things.
- Multimeter: This tool checks if the turbine sensor is working. It measures resistance and voltage to see if they match Nissan's standards.
- Visual Inspection Tools: A flashlight is good for looking at wires and plugs. Check for damage or rust that might affect how the sensor works.
Also, have a wiring diagram of your car's transmission handy. It helps you find the right connections.
You might need basic tools like screwdrivers and sockets to get to or change the sensor. With these, you're ready to start diagnosing the problem.
How to Fix P0717 Nissan Error Code – Step by Step
Step 1:
Connect an OBD-II scanner to your Nissan's system to retrieve any diagnostic trouble codes logged in the engine control module (ECM).
Step 2:
Visually inspect the turbine revolution sensor and its wiring. Look for signs of damage, corrosion, or loose connections that could disrupt the signal to the ECM.
Step 3:
If everything appears intact, use a multimeter to test the resistance of the sensor. Compare the reading to the manufacturer's specifications to determine if the sensor is faulty.
Step 4:
Replace the sensor if it's defective. After replacing it, clear the diagnostic trouble code (DTC) from the ECM memory.
Step 5:
Take your car for a road test to ensure the issue is resolved and the code doesn't reappear. If the problem persists, consider further diagnostics as it may indicate deeper issues within the transmission control module (TCM) or other related electrical components.
Common Diagnosis Mistakes
When diagnosing the P0717 code on a Nissan, don't assume the turbine revolution sensor is faulty right away. First, check the wiring and connectors for any damage. Making this mistake can waste time and money.
Here are some errors to avoid:
- Skipping Resistance Checks: Use a multimeter to test the sensor's resistance. This helps you see if the sensor is damaged or if it still works, which can prevent unnecessary replacements.
- Ignoring Corrosion: Look for rust or dirt on the sensor and connectors. These can affect how the sensor works and might cause incorrect readings.
- Overlooking Related DTCs: Pay attention to other Diagnostic Trouble Codes (DTCs) that might appear. They can give you hints about other problems that might be causing the P0717 code, helping you solve the issue more effectively.
P0717 Nissan Repair Cost
Fixing the P0717 code on your Nissan can cost between $150 and $300, including parts and labor. The price varies based on where you live and how much the mechanic charges, which can be from $80 to $150 per hour.
Usually, the repair requires changing the turbine revolution sensor. This part plays a big role in the total cost. If you decide to fix it yourself and have the skills to handle wiring or replace the sensor, you could save money.
Be ready for extra costs, though. If the first repair doesn't solve the issue, more work might be needed. Additional tests could add to the expenses if the problem continues.
These checks help ensure the error code doesn't come back and that your car runs well. So, plan for more than just the lowest cost to avoid any surprises. Always talk to a professional to get a clear diagnosis and repair plan.
Related Error Codes on Nissan
When you see code P0717 on your Nissan, you might also find codes like P0720, P0716, and P0722. These codes often come from issues in the car's transmission system, usually linked to the input or output speed sensors. Knowing what each code means helps figure out what's wrong and get your car running well again.
Codes P0716 and P0722 are about how the speed sensors work. P0716 shows a problem with how the sensor is working, which can make the car shift gears oddly, similar to P0717. P0722 means the sensor isn't sending any signals, which can make the car hard to drive.
P0720 is about the output shaft speed sensor. Like P0717, it affects how the transmission works and can cause problems with how the car drives. Here's a quick look at what each code means:
| Code | Impact on Vehicle |
|---|---|
| P0716 | Odd gear shifting, performance problems |
| P0722 | No sensor output, might stall |
| P0720 | Different transmission response, shifting problems |
Fixing these codes quickly can stop more serious damage to your Nissan's transmission system.
