What does the code on the TRS sensor mean?
The code is telling you that the computer has recognized a failure in the TRS sensor. The sensor is either sending an erroneous or no signal at all to the computer identifying the gear position. The computer receives signals from the vehicle speed sensor as well as the TRS.
What is the transmission range sensor code for a 2000 Chevy?

How do you replace an external transmission range sensor?
Replacing external transmission range sensors: Block the wheels and apply the parking brake. Place the transmission in neutral Locate the transmission shift linkage. Pull the electrical connector out of the TRS sensor and inspect it closely. Look at the wiring harness location and make sure it’s not rubbing on the shift linkage.
Can a backup light function through a TRS sensor?
The backup lights may also function through the Transmission Range Sensor (TRS) if it is an external component. The code is telling you that the computer has recognized a failure in the TRS sensor. The sensor is either sending an erroneous or no signal at all to the computer identifying the gear position.
How does a TRS test the transmission range sensor?
Verifies that there is a proper voltage and ground present at the Transmission Range Sensor Tests a Contact form of a TRS: a mechanic will back probe each wire on the sensor while someone else changes the gears, and verifies for correct output. There should be a change in the voltage each time the gear position is changed.
Where is the TRS located on a valve?
The function of the Transmission Range Sensor is to tell the ECM or TCM the position of the shift lever. The TRS is most commonly located on the outside of the transmission, however some of them are located inside of the transmission on the valve body. This particular trouble code will set if the ECM does not receive an input.
Where is the range sensor on a transmission?
The Pressure Range Switch is bolted to the valve body of the transmission. It opens up and closes different passages for the transmission fluid as the shift lever is moved. As the gear position moves, a different passage for the transmission fluid will be activated and sensed by this type of range sensor.
Which is the diagnostic code for transmission range sensor malfunction?
P0705 OBD-II Trouble Code: Transmission Range Sensor Circuit Malfunction (PRNDL Input) Cost of diagnosing the P0705 code. P0705 is a diagnostic trouble code (DTC) for “Transmission Range Sensor Circuit Malfunction (PRNDL Input)”.
