Toyota 8353005010 Oil Pressure Switch Assembly

The 8353005010 oil pressure switch is a critical engine management component designed to monitor lubrication system pressure. It features a normally closed contact configuration that opens when oil pressure exceeds the calibrated threshold, extinguishing the warning indicator. The sensor utilizes a brass housing with a single spade terminal for electrical connection and a tapered thread for sealing in the engine block gallery. This unit serves as a direct replacement for Toyota OE part numbers 83530-05010, 83530-0E010, and 83530-14070. It is engineered to meet OEM specifications for pressure calibration, thermal stability, and vibration resistance in gasoline engine applications. Cross-reference interchange includes aftermarket equivalents from major suppliers.
