What is the error code for intermediate shaft speed sensor?
Error Code P0794 is defined as Intermediate Shaft Speed Sensor A Circuit Intermittent. This is a generic error code that usually applies to OBD-II vehicles equipped with automatic transmission. This includes vehicles from, but not limited to, Chevrolet, Chrysler, Dodge, Ford, Lexus, Mercedes Benz, Toyota, and Volkswagen.
What’s the name of the output shaft speed sensor?
There are two of these in every vehicle: one is called the output shaft speed sensor (OSS) while the other is known as the input shaft speed sensor (ISS). The latter measures the rotational speed of the torque converter /input shaft. It detects the internal revolutions of the transmission and sends the data to the PCM.
What are the symptoms of a bad transmission speed sensor?
Symptoms of a Bad or Failing Transmission Speed Sensor. 1 1. Harsh or Improper Shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears 2 2. Cruise Control Does Not Work. 3 3. Check Engine Light Comes On.
What happens if the speed sensor does not work?
If this speed sensor fails, your speedometer may not work. Some odometers use the same sensor as the speedometer, and may cease to function as well. Without a speed sensor, the transmission control unit (TCU) may have a hard time knowing when or how quickly to shift gears.
What does output speed sensor malfunction code mean?
It means that the powertrain control module (or transmission control module) perceives a problem with the output speed sensor (OSS) or its circuit. The sensor in question is the one responsible for the display of real-time vehicle speed. The powertrain control module (PCM) receives input from multiple sensors.
There are two of these in every vehicle: one is called the output shaft speed sensor (OSS) while the other is known as the input shaft speed sensor (ISS). The latter measures the rotational speed of the torque converter /input shaft. It detects the internal revolutions of the transmission and sends the data to the PCM.
Can a bad speed sensor cause a shift?
Harsh or improper shifting Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.
What does it mean when your speed sensor says p0503?
Note that ABS, and particularly wheel speed sensor related codes often contribute to the setting of P0503, which means that all such codes (and especially if such additional codes precede P0503) must be investigated and resolved before a diagnosis and repair of P0503 is attempted.
