The factors influencing the cost of diagnosing and fixing the automobile fault code p1501 include the estimated repair time of 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services. These factors play a significant role in determining the overall cost of addressing the fault code.

The P1501 fault code points to a problem with the Vehicle Speed Sensor (VSS) input signal. When the Powertrain Control Module (PCM) detects that the VSS input signal is outside the self-test range, it triggers the P1501 code and interrupts the test. This code indicates that there is an issue with the VSS during the self-test.

What are the possible causes of the automobile fault code P1501?

If you’re seeing the engine light on or the service engine soon warning light, it could be due to the fault code P1501. This code is often caused by a faulty vehicle speed sensor, an open or shorted vehicle speed sensor harness, or a poor electrical connection in the vehicle speed sensor electrical circuit. Other possible causes include noise on the VSS input signal from radio frequency interference or electromagnetic interference, as well as external sources like ignition wires, the charging circuit, or aftermarket equipment. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins.
