P0705 Fault-Error Code
P0705 fault-error code means circuit failure related to the sensor or PRNDL (Park, Reverse, Neutral, Drive, Low) input in the vehicle's automatic transmission (TR- Transmission Range) . This error code indicates that there is a problem with the sensor or sensors that detect the gear position of the transmission.
Causes of P0705 Fault/Error Code:
There are various reasons that may cause the P0705 fault/error code to appear:
Transmission Range (TR) Sensor Malfunction: The TR sensor is a sensor that detects the gear position. Faults in the sensor itself, such as problems with the electrical connections or mechanical structure of the sensor, can cause error P0705.
Electrical Connection Problems: Problems with the electrical connections related to the sensor, loosening, cutting or oxidation of the wires can lead to the P0705 error.
PRNDL Switch Problem : PRNDL switch is a switch used to determine the gear position. If this switch fails, you may receive error P0705.
Control Module Problem: Transmission control module or general engine control module malfunctions can also cause the P0705 error. If these modules do not work or work incorrectly, communication problems may occur.
Cable Cut or Broken: If the cables related to the transmission sensors are cut or broken, there may be communication problems.
Gear Position Switch Adjustment Problem: This error code may also appear if the gear position switch is in the wrong position or not adjusted correctly.
General Electrical Problems: Problems with the vehicle's general electrical system may prevent the sensor from working properly.
When you encounter this type of error code, it is important to take your vehicle to an auto service and have a qualified technician inspect it.
Symptoms of P0705 Fault/Error Code:
Symptoms of the P0705 malfunction/error code may indicate various problems on the vehicle. Here are the possible symptoms of error P0705:
Gear Selection Problems: One of the most common symptoms is that the vehicle has difficulty selecting the correct gear or the wrong gear selection. The vehicle's gear shifts may be erratic or unexpected.
Failure to Start Vehicle: The error code may prevent or make it difficult to start the vehicle. If the engine does not start or is having trouble starting, this may be related to error P0705.
Check Engine Light: The error code usually causes the vehicle's check engine light to come on. This light is a general warning that there is a problem inside the vehicle.
Gear Lever Problems: Difficulty in the movement of the gear lever, looseness or a resistance that feels different from normal are symptoms that may be associated with the P0705 error.
Inability to Move or Difficult to Move: There may be problems in leaving the park or moving the vehicle. The vehicle may not move because the transmission does not detect the gear position correctly.
Control Module Alerts: On some vehicles, when the P0705 error is detected by the control module, it may display a warning message or light to the vehicle driver.
If you notice one or more of the symptoms mentioned above in your vehicle, the P0705 error code may indicate a possible problem. In this case, it is important to take your vehicle to a car service and have a detailed inspection.
Correcting the P0705 Fault/Error Code:
You can follow the steps below to fix the P0705 fault/error code:
Get a Professional Diagnosis: First, get a professional diagnosis by taking your vehicle to an auto service or authorized mechanic. Identifying the fault and identifying specific problems in your particular vehicle model is the basis for finding the right solution.
Replace TR Sensor or PRNDL Switch : If the TR sensor or PRNDL switch is faulty, it may need to be replaced. These parts may fail or become damaged during their lifetime. Replacement should usually be done by a qualified technician.
Check Electrical Connections: To correct the error, check the electrical connections related to the TR sensor or PRNDL. Loose, broken or oxidized cables can cause such problems. If it is necessary to correct or replace connections, seek help from a professional repairman.
Check Control Module: If the transmission control module or engine control module is faulty, this module may need to be replaced. However, such a change usually requires the intervention of a specialized technician.
Check Cables: Make sure the cables related to the TR sensor or PRNDL are connected correctly. Cut, broken or damaged cables can cause such errors.
Check for Updated Software: Check for updated software versions released by the vehicle manufacturer and update the transmission control module or engine control module if necessary.
It is always the best option to seek professional help to deal with such situations as technical knowledge and equipment may be required to fix the error and troubleshoot the problem. This will help correctly identify the error and implement an effective solution.
Importance of P0705 Fault/Error Code:
There are some factors regarding the significance of the P0705 malfunction/error code:
Gear Selection Problems: P0705 error indicates that the vehicle has a problem with gear selection. This means that the vehicle does not select the correct gear or has difficulty changing gears. This may negatively affect driving safety and make it difficult to control the vehicle.
Starting Problems: The error code may prevent or make it difficult to start the vehicle. This negatively affects vehicle usability and daily driving activities.
Transmission Check Engine Light: The P0705 error usually causes the vehicle's check engine light to come on. This light is a warning to the driver that there is a problem inside the vehicle. It highlights the importance of the problem and alerts the driver to a different situation.
Driving Safety Risk: Wrong gear selection or gear shifting problems may pose a driving safety risk. Experiencing such a problem, especially in traffic or dangerous conditions, can cause a serious accident.
Engine and Transmission Compatibility: Problems with the TR sensor or PRNDL input can affect the compatibility of the engine and transmission. This may prevent the engine from performing properly.
For these reasons, error P0705 should be considered a serious malfunction symptom. When the error code is encountered, it is important to take the vehicle to an auto service or authorized mechanic and have a professional diagnosis performed. If the problem is resolved with early diagnosis and intervention, more serious problems can be prevented and driving safety can be ensured.
