Guide To P0723 OBD Error Code Solutions

<<See All OBD Codes

The P0723 error code indicates that the transmission control module is not converting incoming pulse signals properly. This fault code would be triggered up when the PCM/ECM would determine that there are some defects in the OSS sensor.

But it might still be able to function by substituting values from other sensors to determine torque converter operation, shift timing, as well as the pressure of the EPC.

Trouble code P0723 can be described as Output Speed Sensor Intermittent. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

What causes this problem with the Output Speed Sensor Intermittent?

• Some defects in the output speed sensor
• Input speed sensor might be malfunctioning
• Wiring or connectors might be shorted or defected
• Defects in the shift solenoid
• Distorted engine temperature sensor
• A damaged valve bodies
• The transmission fluid might be contaminated

Common Symptoms

• Engine light ON might start flashing
• Speedometer unsuitable reading
• Possible shifting problems

Looking out for some ways with the help of which you can correct this fault code? Then you have arrived at the correct place. We are here to help you out, so you must check out the steps mentioned below as follows:

• The defected output speed sensor should be replaced
• Carefully replace the faulty input speed sensor
• If you find out that the wiring or connectors are shorted or defected, then they should be replaced
• Restore the defective shift solenoid
• Make sure that the quirky engine temperature sensor is replaced or repaired as per the requirement
• Correct the contaminated transmission fluid

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of exhaust pressure sensor, exhaust pressure control valve, automatic transmission module, egr pressure sensor, turbo kit, turbo car, oil pressure switches, electric turbo, turbo diesel, twin turbo kits and many more. Now all your problems would vanish within no time.

Have a look some steps which you should follow in order to diagnose this fault code:

You must start the diagnostic process by pulling stored codes and freeze frame data using a specialized scanner.

If there is presence of some other codes, then they should be addressed in the order they occurred.

After that you should clear the codes and the vehicle test driven to see if the code returns.

A technician should visually inspect the wiring and involved components, as well as check the transmission fluid for debris.

Then they should utilize a voltmeter to measure the reference voltage and ground signal at the OSS.

If one of these circuits is open, the mechanic will then check for continuity and resistance in the circuits.

If everything else is determined to be operating correctly, your mechanic may use an oscilloscope to live monitor the transmission output speed sensor data.

Most often, the output speed sensor itself needs replacing, or there is a bad connection in the circuit.

Common Mistakes When Diagnosing The P0723 Code

• Most of the time a common mistake of attempting to diagnose this type of code as an engine/turbine speed malfunction, an internal transmission problem, an engine misfire, fuel delivery problem, or a driveline malfunction is made by a lot of mechanics
• Replacing the vehicle speed sensor without any fault can turn out to be a big mistake
