P1507 – OBD-II DTC

OBD-II DTC P1507 – Vehicle Speed Sensor Intermittent Malfunction

DTC P1507 meaning

DTC P1507 refers to an intermittent malfunction of the Vehicle Speed Sensor (VSS). The VSS is responsible for providing the engine control module (ECM) with information about the vehicle’s speed. When the ECM detects that the signal from the VSS is inconsistent or intermittent, it triggers this diagnostic trouble code (DTC). This can affect various systems in the vehicle, including the transmission and cruise control, leading to performance issues.

Common symptoms associated with DTC P1507 may include:

• Erratic or inaccurate speedometer readings
• Transmission shifting issues
• Activation of the check engine light
• Unresponsive cruise control system
• Engine stalling or hesitation during acceleration

DTC P1507 causes

Several factors can lead to the triggering of DTC P1507, including:
