A few days ago I noticed that my oil pressure gauge was reading low pressure. After replacing the sensor I'm getting the same reading.
it appears as 1 wire and I did use teflon tapeIs the sensor 1-wire or 2-wire? If it's 1-wire, it has no dedicated ground wire, it relies on the threads in the block to make the ground. And if you use teflon tape, that insulates the ground and gives an incorrect reading.
Some sensors have a thread cut such that it's tapered and makes a tight oil seal without teflon tape, so that the ground connection there is tight.
no noise or codes, but I can't afford to spend $100 for a gauge.
I was referring to that C-3292 gauge. So basically, All I really need is a 100 psi test gauge?https://www.amazon.com/Pressure-Gauge-Sensor-Universal-Modified/dp/B08V987X4X/ref=asc_df_B08V987X4X/?tag=hyprod-20&linkCode=df0&hvadid=533377215817&hvpos=&hvnetw=g&hvrand=6785652530731287614&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9001872&hvtargid=pla-1458567585087&psc=1
Temporary connection, to see the true pressure.
