Error Code P0705: What It Means & What To Do?

<<See All OBD Codes

Fearing the OBD error code P0705? Well, not anymore! Here’s how you can solve the error code. When the engine control module (ECM) or the transmission control module (TCM) receives an input error from the transmission range sensor (TRS) the code P0705 is stored. The switch is also named or referred to as the pressure switch, park neutral position switch (PNP), the gear selection switch or the PRNDL input switch.

It is observed that when the ECM fails to receive an input the trouble code P0705 sets in. Sometimes, this code is also stored when the ECM receives an input that is unworkable. For example, if the vehicle runs at 50 MPH, and a reverse is being displayed by the transmission range sensor, a code P0705 sets in. Also, there have been incidents registered of the TRS faulting to a point where the ECM was informed being in more than one gear simultaneously. In such situations a code P0705 is stored too.

What causes this problem with the Transmission Range Sensor A Circuit malfunction?

• A disconnected or misadjusted TRS
• Damaged transmission range sensor
• An unsound connector located at the external TRS with loose, burnt or bent pins
• The wiring harness on the external sensor shortened as a result of scraping on the transmission linkage
• A damaged sensor or clogging in the internal valve body TRS port

Terrorized? Want to know the symptoms to OBD code P0705? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with Transmission Range Sensor A Circuit malfunction

Common Symptoms

• P0705 DTC code set with an illuminating malfunction indicator lamp
• The backup lights may not work
• The gear shift to lever would require a movement up and down slightly for a better contact to allow the starter to activate and start the engine
• A failure in activating the starter
• The engine may start only in neutral (in some cases)
• Or would start in any gear
• Erratic shift RPMs
• Falling fuel economy
• A delay engagement displayed at transmission

Here are some ways with which you can correct the P0705 code:

• Any open or short circuit in the TRS circuit should be replaced or repaired
• A defective TCM should be changed or mended
• A distorted ECM should be repaired or replaced
• The transmission fluid and filter should be replaced
• Adjustments should be made of the linkage connecting the shift lever on the transmission to the gear shifter inside the car

Have a look at our superior variety of exhaust pressure sensor, exhaust pressure control valve, EGR pressure sensor, turbocharger, turbo, oil pressure sensor, turbo kit, oil pressure switches, transmission sensor, exhaust valve control and many more. Now all your problems would vanish within no time.

Here listed are some steps which you should follow in order to accurately diagnose this P0705 fault code:

• Utilizing a tech II for diagnosis, replacement of the internal TRS should be made, followed by draining the transmission and taking off the pan. This sensor placed in the bottom of the valve body plays the role of performing all the functions of the transmission. Completely drowned in hydraulic fluid the sensor constantly leads to case problems.
• Often the problem starts due to an O ring sealing or a restricted hydraulic flow. In any case, this complicated problem should be left in the hands of a transmission specialist. The external transmission range sensors should be replaced: the wheels should be blocked and the parking brakes should be applied.
• Next, the transmission should be placed at neutral located at the transmission shift linkage. In case of front wheel drive vehicles, it located on the top of the transaxle. And on the rear wheel drive vehicles, it’s located on the driver’s side. Next the electrical connector should be pulled out of the TRS sensor and should be inspected. All the corroded, bent or pushed out pins in the sensor should be checked.
• The connector on the harness should also be checked for the same, also the female ends that should be on the right place. A separate replacement should be made of the harness connector if it fails to save with cleaning or straightening of the female connectors. A little amount of dielectric grease should be placed in the connector before reconnecting.
• The wiring harness location should be looked at to ensure it doesn't end up rubbing on the shift linkage. All the wires broken or short circuited due to deficient insulation should be checked and all the sensors should be verified too for any loose ends. If it appears to be loose, the parking brake should be turned on with the transmission in neutral. Next, the key should be turned on and the TRS should be swiveled until the back lights illuminate.
• At this point the two bolts on the TRS should be tightened. The TRS must be rotated until 5mm drill bit till it fits into the hole if the vehicle in question is a Toyota. In case before tightening it down, the nut should be removed carefully retaining the gearshift lever and then lift the lever off the electrical connector from the sensor.
• Two bolts should be removed securing the sensor to the transmission. It is recommended that you shouldn’t drop the bolts in order to turn it into a several hour tough job. Lastly, the sensor should be lifted off the transmission. Carefully look at the new sensor to ensure the tick marks on the shaft and the case where it’s marked “neutral” are all in alignment. The sensor over the shift lever shaft should be installed and the two bolts should be tightened. Then the electrical connector should be plugged in and the shift lever should be re-installed with all the nuts tightened properly.

Common Mistakes When Diagnosing the P0705 Code

Fearing a misdiagnose? Well, we at Parts Avatar have listed out a few common mistakes that should be avoided while diagnosing the error code P0705

• It is not that extremely damaging, except that one can fail to pass inspection with a check engine light
• Along with the check engine light there may be a no start condition
• Irregular shifting may occur
• The vehicle may enter into limp mode, stopping you to go over 40 MPH
