What does P0722 mean?
Output Speed Sensor No Signal
OBD-II Code P0722 is defined as a Output Speed Sensor No Signal. When the code P0722 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is not seeing a consistent speed signal from the Transmission’s Output Speed Sensor.
How do you test an output shaft speed sensor?
Connect the VSS to a power drill so you can simulate the rotation of the vehicle’s transmission and read the multimeter to see if the voltage increases as the speed increases to check if the sensor is working properly.
What does Engine code P0715 mean?
What Does Code P0715 Mean? P0715 definition: Malfunction in the transmission input/turbine speed sensor circuit. Issue Severity: SEVERE – Stop driving immediately. Repair Urgency: Fix this code immediately (same day if possible) to avoid internal engine or transmission damage.
What is code P0717?
Code P0717 is triggered when the transmission’s Input Speed Sensor isn’t providing a signal. This is a critical problem because with out this signal, the Transmission Contorl Module or TCM can’t properly shift the vehicle from gear to gear as the vehicle needs to change speed and rates of acceleration.
What causes a speed sensor to malfunction?
Also, the plastic portion of the sensor can become brittle after prolonged exposure to the elements. The magnetic portion of the sensor may also become worn and damaged over time. The speed sensor measures the rotation of a toothed wheel on a shaft inside the transmission to determine how fast your car is going.
What does the p0722 code on a speed sensor mean?
Cost of diagnosing the P0722 code. P0722 is a diagnostic trouble code (DTC) for “Output Speed Sensor No Signal”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
How long is the warranty on a p0722 code?
All our repairs are backed by our 12-month / 12,000-mile warranty. A P0722 code is stored when the PCM gets an incorrect or irrational input signal from the transmission’s output speed sensor.
What causes a p0722 code on a Toyota Corolla?
There are a few common issues that can cause a P0722 code to be stored, including: A faulty or damaged transmission output speed sensor A faulty temperature sensor for the engine coolant A faulty or damaged shift solenoid Contaminated transmission fluid A problem with the valve body A problem with the wiring or connector for the output speed sensor
What happens when the PCM cannot detect the correct speed signal?
Basically, when the PCM cannot detect a consistent or expected speed signal from the transmission’s output speed sensor, it will be unable to correctly predict how and/or when to shift up or down appropriately.
