How do you change a oil pressure switch on a Honda Odyssey?

Answer 1

Looking at a photograph, I think it just screws into the engine with an electrical attachment on the end.

I have done this on a 2003 Odyssey EX. The oil pressure switch is located on the oil pump assembly, which is behind the passenger side front wheel. There are 2 sensors - the oil pressure switch is the furthest one and least accessable. You need to pull off the connector, which is very tight. I used a pair of pliars with a cloth to twist it off. Be carefull not to damage the connector. There are 2 different switches available for the 2003, each with different tread sizes. TIP: buy both switch types before you start, that way you can return the one you don't need. I used a regular wrench to remove/install the switch, and it stopped the leak that prompted the repair. Another TIP: watch how long your wrench is, because you can catch the Power Steering pressure switch wiring harness and break the thin wires, leading to a much more expensive repair.... Next time I will disconnect the power steering pressure switch first and pay more attention. Or buy a shorter wrench.... Good luck!
