Frequently Asked Questions
What does the oil pressure switch do?
It senses engine oil pressure and opens or closes the circuit that operates the dashboard oil-pressure warning light or gauge, alerting you when pressure drops below the switch's set threshold.
How do I know if the switch is failing?
Common signs are a warning light that stays on or flickers when oil pressure is confirmed good, an erratic gauge reading, or oil seeping from the switch. Diagnose the cause before replacing.
Does PS-232 fit my vehicle?
It is listed for many 1987-1998 Chrysler, Dodge, and Plymouth models. Check the Buyer's Guide tab against your exact year, make, and model before ordering.
What numbers does this switch interchange with?
It cross-references S4080, 8152, 4687814, 5233396, PS204, OP6668, 19021106, and 89057507. Its own manufacturer part number is PS-232.
Will replacing this switch fix my oil warning light?
If a faulty switch is the cause, replacing it restores an accurate signal. If the light comes from genuinely low oil pressure or another fault, that must be diagnosed and addressed separately.
