Is your Volvo or Detroit Diesel Series 50 or 60 engine showing oil pressure warning lights or acting up? This X AUTOHAUX oil pressure switch/sensor might be the fix you need. It's a direct replacement designed to match the OEM part number 23532797. It's made from a combination of metal and plastic, with a 3-pin electrical connector and an M13 x 1.5 thread size for installation. The sensor's job is to monitor your engine's oil pressure and send that information to your dashboard gauge or computer. A faulty sensor can give false readings, trigger warning lights, or even affect engine performance. Replacing it is usually a straightforward job for a DIYer with some mechanical knowledge or a mechanic. Important: This is an aftermarket part, not made by Volvo/Detroit, but it's built to OE specifications. Before ordering, double-check that this part number (23532797) matches your old sensor, and confirm the fitment for your specific engine model and year. Always disconnect the battery before working on electrical components. A quality replacement part like this can restore proper engine monitoring and peace of mind.
