What to do if your car has a p0706 code?
Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. The cost to diagnose the P0706 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type.
What causes a p0706 shift linkage to fail?
Misadjusted shift linkage (if P0706 was caused by an “illogical” TRS signal) Bent terminal pin in TRS (or TCM, or inline) wiring connector Terminal pushed out of TRS (or TCM, or inline) wiring connector TRS signal wire shorted to another wire in its harness
What causes a p0706 code on a TRS?
P0706 faults are often caused by a faulty TRS, or by a wiring problem (broken wire, poor connection, etc.) between the TRS and the TCM. In some cases, the “bad” TRS signal is only temporary, and the problem “heals itself” after a few seconds (I have personally seen this happen at startup in very cold temperatures).
Where is the transmission range sensor located?
The transmission range sensor may also be called the neutral safety switch or PRNDL input. Located outside the transmission box or on the valve body, its job is to communicate the current gear selection or shift lever position with the TCM or PCM.
What does P0706 mean?
What Does the P0706 Code Mean? Diagnostic trouble code (DTC) P0706 stands for “Transmission Range Sensor “A” Circuit Range/Performance.” It warns that the PCM detects an incorrect signal from the TR sensor.
How much does it cost to replace a sensor in the transmission?
The average cost for transmission position sensor replacement is between $255 and $305. Labor costs are estimated between $137 and $172 while parts are priced between $118 and $132. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
What does transmission range sensor circuit high input mean?
The presence of a P0708 diagnostic trouble code means that the transmission range sensor / neutral safety switch is sending the wrong signals back to the ECM.
Can you drive with P0706 code?
How Serious is the P0706 Code? Because the vehicle's operation could suffer and the transmission may go into “limp” mode, the P0706 code is considered potentially serious, and it is recommended that you take your vehicle to your local mechanic for diagnosis and repair as soon as possible.
How do you fix a transmission range sensor circuit?
What repairs can fix the P0705 code?Repairing an open or short in the TRS circuit.Replacing a faulty TCM.Replacing a faulty ECM.Changing the transmission fluid and filter.Adjusting the linkage connecting the shift lever on the transmission to the gear shifter inside the car.
How long does it take to replace a transmission sensor?
If you get a professional to do the job, then it should take about 2 to 3 hours to replace the range sensor. It may take longer to fix if the sensor is located on the inside of the transmission box as the mechanic will have to disassemble it and put it back together.
Can you clean a transmission speed sensor?
In this case, the sensor may not have to be replaced as the sensor can be cleaned off. Yet, only a mechanic should make that determination because there may be damage to the electrical part of the sensor. Normally, the transmission speed sensor is diagnosed with a scan tool which is read by a mechanic.
What happens when a transmission sensor goes out?
A failing transmission position sensor may no longer send the right signals to the Powertrain Control Module, or PCM. Without signals from the position sensor, the PCM will no longer know when to shift the transmission's gears out of park into a moving gear. Transmission shifts into the wrong gear.
How do you test a transmission range sensor?

What does a transmission range sensor control?
Transmission range sensors record the transmission speed. This information is required by the control unit to regulate the shifting pressure when shifting gears and to decide which gear needs to be engaged at which point.

What does a transmission range sensor do?
Transmission range sensors record the transmission speed. This information is required by the control unit to regulate the shifting pressure when shifting gears and to decide which gear needs to be engaged at which point.
What causes code P0705?
When code P0705 is triggered, the ECM or TCM is not seeing what gear the transmission is in (park, reverse, neutral, drive, or low). If the ECM or TCM can't verify that the transmission is in park or neutral, it will not allow the vehicle to start.
How do I fix error code P0707?

What is the P0706 code?
The P0706 code is a generic powertrain code related to the transmission. This code is non-emission related. The transmission range sensor circuit is not communicating correct data to the engine control module (ECM). This code only applies to vehicles with an automatic transmission.
Why is P0706 code considered serious?
Because the vehicle’s operation could suffer and the transmission may go into “limp” mode, the P0706 code is considered potentially serious, and it is recommended that you take your vehicle to your local mechanic for diagnosis and repair as soon as possible.
What is the code for a transmission sensor?
P0706 is a diagnostic trouble code (DTC) for "Transmission Range Sensor Circuit Range/Performance". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $0.0 .

Definition
The Transmission Range Sensor is also sometimes called Park/Neutral switch or Safety switch. It communicates with the vehicle’s transmission control module and PCM, and is attached to the manual valve of transmission.

What causes a P0706?
P0706 faults are often caused by a faulty TRS, or by a wiring problem (broken wire, poor connection, etc.) between the TRS and the TCM. In some cases, the “bad” TRS signal is only temporary, and the problem “heals itself” after a few seconds (I have personally seen this happen at startup in very cold temperatures).
What does P0706 mean?
What Does Code P0706 Mean? P0706 means that the Transmission Control Module (TCM) [or Powertrain Control Module (PCM), a combined engine and transmission controller used in many vehicles] sensed a “bad” signal from the Transmission Range Sensor (TRS). To explain, let’s first look at the automatic transmission shift linkage.
What is an invalid TCM code?
An “invalid” code: The TCM senses a TRS combination that does not match ANY valid position. An “illogical” code: The TCM senses a valid code, but in an unusual or illogical fashion.
How does TCM determine transmission position?
Therefore, the TCM can determine the transmission position by comparing the actual “code” from the signal wires (Grounded-Open-Open-Grounded, for example) to the proper code for each position. There are two types of “bad” signals which can cause a P0706 fault: An “invalid” code: The TCM senses a TRS combination that does not match ANY valid ...
