Need some help diagnosing, But won't let me post! 09 RX8 R3
Intermittent Oil Level Light
The vehicle still has an oil level light flashing. However, it is more often than before, no set MIL on. OMP Pressure is constantly monitored with scan tool daily driving and track, Scanned code found code P1684, monitor data OMP pressure will drop to 0 PSI, this triggering the code P1684- OMP Low Oil Pressure, the light goes away immediately after restarting. Observed that Low oil pressure gets triggered on local driving within 8-15 minutes (seems to be related to RPM), However, 1 hour with 80MPH+ cruising on the interstate and a Full track day with six 30min sessions with full throttles - No oil light observed at all. On the drive home, on an empty interstate, starts doing a single pull from 60MPH - 125MPH indicated, monitored scan tool found OMP Pressure reading at 32 PSI, exceeding the limit and triggering code P1685 OMP Pressure high. Now the vehicle has both P1684 OMP Pressure low and P1685 OMP Pressure high, codes stored in PCM. No MIL illuminated.
Items that were replaced:
Oil Pressure Sensor and fix oil leaks (Last visit Mazda Dealer Found It faulty and replaced it due to it reading pressure ignition on and eng. off)
Oil Control Valve
Oi level Sensor
