O.k.,this code sets for any of these issues here: • Metering oil pump malfunction • Metering oil pump switch malfunction • Connector or terminal malfunction • Open circuit in wiring harness between main relay terminal C and metering oil pump terminal C • Short to GND in wiring harness between main relay terminal C and metering oil pump terminal C • Open circuit in wiring harness between main relay terminal C and metering oil pump terminal D • Short to GND in wiring harness between main relay terminal C and metering oil pump terminal D • Open circuit in wiring harness between metering oil pump terminal A and PCM terminal 2V • Short to GND in wiring harness between metering oil pump terminal A and PCM terminal 2V • Open circuit in wiring harness between metering oil pump terminal E and PCM terminal 2W • Short to GND in wiring harness between metering oil pump terminal E and PCM terminal 2W • Open circuit in wiring harness between metering oil pump terminal B and PCM terminal 2Y • Short to GND in wiring harness between metering oil pump terminal B and PCM terminal 2Y • Open circuit in wiring harness between metering oil pump terminal F and PCM terminal 2AB • Short to GND in wiring harness between metering oil pump terminal F and PCM terminal 2AB • Short to GND in wiring harness between metering oil pump switch terminal A and PCM terminal 2N • PCM malfunction The oil metering pump can fail and cause this here.It sends a small amount of oil to the rotor housing to lubricate seals.The most common cause is the oil metering pump switch needing replaced or the oil metering pump itself needing replaced.This will have to be tested further to locate the fault to be sure and then from there repaired to correct this issue.
