When you first turn on the key, you should get an alarm
, this alarm should go off very soon after the engine
starts, that is the low oil
pressure alarm, I think what you are mistaking for a transducer is actually a switch that operates the low oil pressure alarm.
I will likely one day add a gauge, but the alarm is the one I consider the most important, unless your watching the gauge very often
I have the 4JHE also. I like gauges, always owned high end sports cars, Jags, etc that come with full instrument package so I'm used to watching gauges.
On my boat
I added oil and temp gauges at the helm
years ago. I often take a dock cruise
and the gauges are useful to know how long to run the engine
, usually between 20 and 60 minutes at 1800rpm and jockey between fwd and reverse to give it a load.
