LOW OIL PRESSURE STOP ENGINE Message

  1. This message displays when oil pressure switch is closed for more than 2 seconds when engine is running. PCM communicates to IPC that engine is running. If this communication line is lost, a Code I034 will be set. If Code I034 is set when ignition is on and engine is off, IPC will assume engine is running and display message on DIC.
  2. If Code I034 is not set, and message is displayed when oil pressure is known to be greater than 5 psi at idle, check for short to ground in Tan wire circuit between IPC connector terminal D5 and oil pressure switch. See Figure . Also check for shorted pressure switch.
  3. If oil pressure is known to be less than 3 psi at engine idle and message does not display, check for open in Tan wire circuit or in Black ground wire circuit from switch.
