Review on Toyota 83530-0E010 Genuine Oil Pressure Switch Assembly by Jeremiah Small

Installed in a 2003 Toyota Corolla. On this vehicle, the sensor is easily accessible from the top of the engine compartment above the oil filter. You'll need a 22-24mm head (sorry I forgot what size, but it definitely doesn't look like 19mm or smaller). Simply unplug the old sensor, unscrew the old sensor, apply some teflon tape or other sealant to the threads of the new sensor, screw in the new sensor and finally reconnect the wire connector. This part is exactly the same as the old one. faulty part.
