Low Oil Pressure Warning Never/Always On

  1. Oil Pressure Check  - Check engine oil pressure at 1000 RPM and 3000 RPM. If engine oil pressure is 28-43 psi (196-294 kPa) at 1000 RPM, and 43-57 psi (294-392 kPa) at 3000 RPM, go to next step. If engine oil pressure is not as specified, repair engine as necessary.
  2. Bulb Check  - Turn ignition off. Remove low oil pressure indicator bulb from instrument cluster. Ensure continuity exists between bulb terminals. If continuity exists, go to next step. If continuity does not exist, replace bulb.
  3. Oil Pressure Sensor Check  - Turn ignition off. Disconnect oil pressure sensor connector, located at top right front of engine. Check resistance between ground and oil pressure sensor terminal with engine off, then with engine running. If resistance is less than 5 ohms with engine off, and greater than 10,000 ohms with engine running, go to next step. If resistances are not as specified, replace oil pressure sensor.
  4. Indicator Circuit Check  - Turn ignition off. Disconnect instrument cluster C210 (Black) connector. Check resistance between instrument cluster connector C210 terminal B6 (Yellow/Red wire) and ground. Check resistance between instrument cluster connector C210 terminal B6 (Yellow/Red wire) and oil pressure sensor connector. If resistance is greater than 10,000 ohms between instrument cluster and ground, and less than 5 ohms between instrument cluster and sensor, replace instrument cluster printed circuit board. If resistances are not as specified, repair Yellow/Red wire.
