SPN 1319 - Engine Low Oil Pressure
Indicates low oil pressure in the engine.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine's oil pressure is too low, which can lead to serious engine damage if not fixed. It usually means there's not enough oil, bad oil pump, or a blocked oil passage.
What the computer is actually seeing
The ECM monitors oil pressure through a sensor, expecting it to be between 20 and 80 psi under normal operating conditions. Values below 20 psi trigger the code.
What a healthy reading looks like
Normal oil pressure should be between 20-80 psi at engine operating temperature.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the engine oil level; it should be between the min and max marks on the dipstick. If low, top off with the correct oil type and retest.
- 22. Inspect the oil pressure sensor wiring and connector for damage or corrosion. Repair as necessary and retest.
- 33. Use a mechanical oil pressure gauge to verify the actual oil pressure at the engine. If pressure is below 20 psi, further diagnosis of the oil pump or passages is needed.
- 44. If the sensor reading is good but the code persists, check for internal engine issues like wear or blockages.
Common causes
- Low oil level
- Faulty oil pressure sensor
- Oil pump failure
- Clogged oil filter
- Oil passage blockage
