DTC 13 - Engine Shutoff Solenoid Circuit Fault: Notes

1985 Chevrolet Chevy Van G20, 6.2 C, StandardSECTION Notes
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 1994 GMC Yukon, 1994 GMC Suburban, 1994 GMC Pickup, 1994 GMC Cab & Chassis, and 1994 GMC C3500 HD. However, it is still accessible from the selected car via links, so may be relevant.

When ignition switch is in OFF position, engine shutoff solenoid is in NO FUEL position. By providing a ground path, PCM energizes the solenoid which then allows fuel to pass into the fuel pump. DTC 13 will set when:

  • Ignition voltage is present on the engine shutoff solenoid control circuit when PCM is requesting engine shutoff solenoid on.

Or 

  • No ignition voltage is present on the engine shutoff solenoid control circuit when PCM is has requested engine shutoff solenoid off.

PCM will default to a current and history DTC 13 will be

stored.

NOTE: Test numbers refer to numbers on diagnostic chart.
  1. Check for open circuit from ignition switch to solenoid.
  2. Check the engine shutoff solenoid control circuit for open from solenoid to PCM.
