NOTE:

Due to restricted access to the oil pressure switch, it is recommended to first check VVT oil pressure at the oil temperature sensor. Refer to DIAGNOSIS AND TESTING .

CAUTION:
Threads in block are 1/8"-28 British Standard Pipe (BSP). Do not install a National Pipe Thread (NPT) threaded adapter, this could crack the cylinder block.
Install an 1/8-28 BSP male to 1/8-27 female threaded adapter (2).
Install an oil pressure gauge (1).
Start engine and record oil pressure.
CAUTION:
If oil pressure is 0 at idle, do not perform the 3000 RPM test
If oil pressure is 0 at idle, shut off engine. No oil pressure or low oil pressure at the oil pressure switch can be due to the following:
- Pressure relief valve stuck open.
- Clogged oil pump pick-up screen.
Remove the oil pan and inspect for debris. Refer to PAN, OIL, REMOVAL .
Remove the oil pressure relief valve. Refer to VALVE, OIL PRESSURE RELIEF, REMOVAL .
Inspect the oil pressure relief valve. Refer to VALVE, OIL PRESSURE RELIEF, INSPECTION .
If pressure relief valve is OK, replace the balance shaft module assembly. Refer to PUMP, ENGINE OIL, REMOVAL .
