Operation



Specific to:

The oil pressure switch provides a ground for the instrument cluster low oil pressure indicator light. The switch receives an oil pressure input from the engine main oil gallery. When the engine oil pressure is greater than 4 psi, the switch contacts open, providing an open circuit to the low pressure indicator light.

Dodge Grand Caravan 2008-2009

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Disconnect the electrical connector from the sensor.
  4.  
  5. Connect a jumper wire from the harness wire to a ground on the engine (if single wire) or across the 2 harness wires.
  6.  
  7. Turn the ignition switch ON. The low oil pressure warning light should go ON.
  8.  
  9. Disconnect the jumper. The light should go OFF. If the lamp does not light when the circuit is completed, suspect a faulty bulb or wiring problem.
  10.  
  11. With the engine OFF and the oil pressure at 0 psi, check for continuity across the sensor body.
    1. On single-terminal sensors, check continuity between the sensor terminal and a ground on the sensor body or the engine block.
    2.  
    3. On 2-terminal sensors, check for continuity between the 2 terminals.
    4.  

  12.  
  13. If there is no continuity, replace the oil pressure sensor.
