Introduction
The P0705 code is an error code that can occur in certain cars made after 1996. It indicates a problem with the transmission range sensor, which is responsible for sending information about the transmission to the car’s computer. This code can be triggered if the sensor is not working properly and is not sending enough information to the computer or if the sensor is not sending any information at all. This can cause issues with the transmission and may cause the car to not shift gears properly.
Description
The P0705 code is an error code that indicates a problem with the Transmission Range Sensor (TRS), also known as a pressure switch or gear selection switch. This sensor tells the powertrain control module (PCM) the position of the shift lever and is typically located on the outside of the transmission. When the PCM doesn’t receive sufficient input from the TRS or receives an input that is impossible (such as the vehicle being in reverse while moving at high speeds), the P0705 code is triggered. This can happen if the TRS fails or if it tells the PCM that it is in multiple gears at the same time. The main function of the TRS is to record the transmission speed which is necessary for the control unit to regulate gear shifting and decide which gear to engage at a certain point.
Causes of P0705 Code
- Transmission range sensor wiring or connectors that are corroded, worn, or damaged
- Misaligned or faulty transmission range sensor
- Contaminated transmission fluid
- Defective shift linkage
- Damaged transmission valve body
- Faulty or damaged PCM (powertrain control module
Various Symptoms Of P0705 Code
A P0705 code is an indication of a problem with the sensor that monitors the position of the transmission gear lever. When this sensor malfunctions, it can cause a variety of performance issues for the driver. These may include:
- The Check Engine Light coming on
- Difficulty shifting gears
- The vehicle starting in a gear other than park or neutral
- Delays when shifting gears
- Difficulty getting the vehicle into gear
- Inconsistencies in the dash indicators (PRNDL)
- Reverse lights not turning on
- Harsh engagement when shifting into gear.
It is recommended to have a professional mechanic diagnose and fix the problem to avoid further damage
How To Fix P0705 Error Code
P0705 is a diagnostic trouble code that indicates a malfunction in the transmission range sensor circuit. To fix this issue, some possible steps to take are:
- Inspect the wiring and connectors of the transmission range sensor for any damage or loose connections.
- Check the sensor itself for any physical damage or wear.
- Verify the transmission fluid level and condition, if necessary drain and replace it.
- Check for other diagnostic trouble codes that may be related to the P0705 code.
- If the above steps do not resolve the issue, it may be necessary to take the vehicle to a professional mechanic or dealership for further diagnosis and repair. Remember that the solution may vary depending on the specific make and model of the vehicle.
