Checking Engine Oil Pressure

WARNING: This page is about a different car, the 2023 Jeep Grand Wagoneer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the oil pressure sensor. Refer to ENGINE OIL PRESSURE (EOP) SENSOR .
  2. Install gauge assembly (special tool #C-3292A, Gauge, Pressure).
  3. Run the engine until the thermostat opens.
  4. Observe oil pressure gauge for specified readings:
    • Curb Idle: 25 kPa (4 psi) minimum amount of pressure to lubricate engine
    • 1000 RPM: 234 kPa (34 psi) for a VVT engine to activate VVT
    • 3000 RPM: 170-758 kPa (25-110 psi)
  5. If oil pressure is 0 at idle, shut off engine. Check for a clogged oil pick-up screen or a pressure relief valve stuck open.
