What is VSS low signal?
What is VSS low signal?
OBD II fault code P0502 is a generic code that is defined as “Vehicle speed sensor (VSS) -low input”, and is set when the PCM (Powertrain Control Module) detects a lower than expected input signal from the Vehicle Speed Sensor (VVS).
What is a VSS input?
After registering data, the two transmission speed sensors, also commonly referred to as vehicle speed sensors (VSS), send data to the powertrain control module (PCM), which compares these two inputs and calculates which gear the transmission should engage for efficient driving.
What does the OBD II fault code p0502 mean?
What Does Code P0502 Mean? OBD II fault code P0502 is a generic code that is defined as “Vehicle speed sensor (VSS) -low input”, and is set when the PCM (Powertrain Control Module) detects a lower than expected input signal from the Vehicle Speed Sensor (VVS).
Why does my VSS have a p0502 code?
If the PCM detects a low input voltage signal from the primary VSS, a code P0502 will be stored and a malfunction indicator lamp may be illuminated. A low voltage input condition may be caused by either an electrical or mechanical problem. A typical VSS or vehicle speed sensor:
Is the p0502 speed sensor a low input?
2005 C3 Benzina p0502 fault. we have a 2005 semi-otomatic C3 benzina.Engine warning light appears as soon as the speed reaches 90km .Our car goes like a turtle and we are going crazy.l took it to the service a few times and they connected it to the computer and p0502 fault appeared.It is a speed sensor problem.they repaired it …
What causes a low input OBD code on a speed sensor?
Possible causes for this code include: Excessive metal debris buildup on speed sensor/s. A defective wheel speed or vehicle speed sensor. Cut or otherwise damaged wiring harnesses or connectors (especially near speed sensors)
