What does the P1705 code mean?
The P1705 code is a generic powertrain code that indicates a problem with the transmission range sensor circuit. Specifically, it means that the transmission range sensor circuit has malfunctioned, causing the transmission to not shift correctly. The transmission range sensor is responsible for communicating with the engine control module and the transmission control module to ensure the proper gear selection.
When the code appears, the transmission may go into “limp mode,” which is a default mode that allows the vehicle to operate at reduced power until the issue is resolved. This can cause a reduction in fuel economy and performance, and in severe cases, the vehicle may not move at all.
What causes the P1705 code?
While the transmission range sensor circuit malfunction is the main reason behind this code, there could be other common threats that lead to the code’s activation. Here’s a complete overview of these to help you deal with the code precisely:
Faulty transmission range sensor
The most common cause of the P1705 code is a faulty transmission range sensor. The sensor may become worn or damaged over time, or it may fail due to an electrical or wiring issue.
Malfunctioning shift solenoid
Another potential cause of the P1705 code is a malfunctioning shift solenoid. The shift solenoid is responsible for controlling the flow of transmission fluid, which allows the transmission to shift gears. If the solenoid is not functioning correctly, it can cause the transmission to shift erratically or not at all.
Wiring or electrical issues
Wiring or electrical issues can also cause the code. Corroded or damaged wires, loose connections, or damaged connectors can all cause problems with the transmission range sensor circuit.
Transmission control module issues
In some cases, the issue may be with the transmission control module itself. The module may be malfunctioning or may need to be reprogrammed.
Which car models does the P1705 code affect the most?
The P1705 code can affect a wide range of vehicles, but some models are more prone to the issue than others. In particular, older Nissan vehicles are known to experience the code, including the following models:
- Honda Civic: The Civic is a popular compact car that has been known to experience issues with the transmission range sensor circuit. Some drivers have reported that their Civics have difficulty shifting into gear or shifting between gears due to this problem.
- Toyota Camry: Some Camry owners have reported issues with the transmission range sensor circuit, which can cause problems with shifting and acceleration.
- Nissan Altima: The Altima is another midsize sedan that is popular in the United States. Some Altima owners have reported issues with the transmission range sensor circuit, which can cause the car to shift erratically or fail to shift into gear.
How to diagnose the P1705 code
Diagnosing the exact source of the problem with this code is pretty tough, so it often requires having some specialized tools and equipment. Here’s what you can do to determine the problem with the code regardless of whether you have these tools or not:
Check the transmission fluid level and condition
The first step in diagnosing the code is to check the transmission fluid level and condition. Low or dirty transmission fluid can cause the transmission to malfunction, which can trigger the P1705 code.
Use an OBD2 scanner
The next step is to use a scan tool to read the codes stored in the vehicle’s computer. The scan tool can provide information about the specific code and the vehicle’s transmission system.
Check the wiring and connections
Next, inspect the wiring and connectors in the transmission range sensor circuit. Look for damaged or corroded wires, loose connections, or damaged connectors.
Test the transmission range sensor
If the wiring and connectors are in good condition, the next step is to test the transmission range sensor. This can be done using a multimeter or an oscilloscope to test the sensor’s electrical output.
Inspect the shift solenoid
If the transmission range sensor is functioning correctly, the next step is to inspect the shift solenoid. This can be done using a multimeter to test the solenoid’s electrical output.
How to fix the P1705 code
There are various ways of fixing this code and removing it for good and it all depends on what has caused the issue in the first place. That’s why diagnosing it properly is so important, and you can use one of the following methods to figure out a solution afterward:
Replace the transmission range sensor
If the issue is a faulty transmission range sensor, it will need to be replaced. The cost of a replacement sensor can range from $50 to $200, depending on the make and model of the vehicle.
Replace the shift solenoid
Replacing the shift solenoid is sometimes needed to restore the proper gear range in a vehicle with an automatic gearbox. The cost of a replacement solenoid can range from $150 to $400 on average but could be even higher for some premium models.
Repair the wiring or electrical issues
If the issue is with the wiring or electrical system, the damaged or corroded wires will need to be repaired or replaced. This can cost anywhere from $50 to $500, depending on the extent of the damage.
Reprogramming the TCM
Finally, you can solve the problem by reprogramming the TCM in cases where the bad module readings have led to the code triggering. Of course, this isn’t always a solution and it requires a thorough inspection of the module to determine if you should be reprogramming it in hte first place, let alone replacing it.
How to prevent the P1705 code
Preventing the P1705 code requires routine maintenance and care of the transmission system. Here are some preventative measures to take:
- Regular transmission fluid changes
- Inspecting the wiring and connections
- Properly maintaining your car’s transmission system
Finally, regular inspections and repairs can help prevent the code and other transmission-related issues.
Ultimately, this code can be pretty bad for car owners as it often leads to issues with the transmission and the ability to shift gears at the right time. By solving hte issue behind the code and removing it, you can save yourself from the trouble of doing transmission repairs in the long run, so let this guide be your guide through the task.
What are the symptoms of the P1705 code?
The symptoms of the P1705 code can vary depending on the vehicle. Some common symptoms include harsh shifting, incorrect gear selection, and a failure to shift into gear.
How can I prevent the P1705 code from occurring?
Preventing the P1705 code requires routine maintenance and care of the transmission system. This includes regular transmission fluid changes, inspection of the wiring and connectors, and proper maintenance of the transmission system.
What should I do if I encounter the P1705 code?
If you encounter the P1705 code, it’s best to consult with a qualified mechanic who can diagnose and repair the problem. Ignoring transmission issues can lead to further damage and more costly repairs down the line.
