Checking oil pressure (Honda Civic 6)

A drop in oil pressure can be considered a sign that the engine needs a refurbishment. The oil pressure warning light is not a diagnostic tool for the lubrication system, but only informs the driver of a dangerous drop in oil pressure. Even the oil pressure gauge built into the instrument panel, despite the great detail of the information it provides, can only be considered an informational device. To obtain oil pressure data that can then be compared with the requirements Specifications, it is necessary to use mechanical (not electric) pressure gauge combined with a precise tachometer.



1a. Locate the oil pressure switch/sensor assembly (see accompanying illustrations). On Civic models, the oil pressure switch is located directly above the oil filter (the filter is removed in the picture).



1b. On Integra models, the oil pressure switch is located in the oil filter assembly. 2. Remove the switch and replace it with a mechanical pressure gauge adapter. Use Teflon sealing tape or FUM tape to seal the threaded connection of the adapter.



3. Connect an accurate tachometer to the engine according to the manufacturer's instructions.

4. Check the oil pressure while operating at the specified Specifications revolutions and the engine warmed up to normal operating temperature. Compare the measurement results with the standard data. If the oil pressure is excessively low, the degree of wear of the bearings and the oil pump should be assessed.
