Description: SCP (J1850) Invalid or Missing Data for Engine Sensors
Common Diagnostic Steps:

  • Check for any other stored trouble codes that might be related to communication issues.
  • Inspect the wiring and connectors associated with the SCP (J1850) bus for damage, corrosion, or loose connections.
  • Verify the integrity of the engine sensors’ data by using a scan tool to monitor live data streams.
  • Test the vehicle’s battery and charging system to ensure proper voltage levels are maintained.
  • If equipped, check the operation of any aftermarket devices connected to the SCP (J1850) network that may interfere with communication.
  • Consult technical service bulletins (TSBs) for known issues related to this code on your specific vehicle model.
  • If necessary, perform a continuity test on the SCP (J1850) circuit using a multimeter.
  • Consider reprogramming or updating the vehicle’s control modules if software-related issues are suspected.
