Oil pressure sensor from the top

Thanks! However my torque tool was too big to use since I did it from the top using a Harbor Freight $8 19mm crowfoot tool and a 6" extension and took less than 15 minutes. I went by feel and works great without leak. It felt like a Porsche colonoscopy exam.LOL Price on these sensors have gone up from $50 to $75-$118. I purchased a Porsche 928 oil sensor for $25 back in 2003.

I should probably just buy that tool and do it myself.

And find yourself a new Indy mechanic. It's not rocket science, which might be why not to many rocket scientists switch career paths to automotive mechanics.

Thanks for posting this thread with pictures. This thread saved me a bunch of money.

My oil pressure sensor has been acting up...pressure periodically drops to zero, then comes back up.

I just ordered a replacement and will get it installed next week.

As previously mentioned try using low grit sand paper on the connector and thoroughly clean the connectors with alcohol following the sanding. Then paste a small amount of dialectric grease on both connectors. I did this and worked a charm��. It took maybe five minutes.

Repair Completed

Symptoms were erratic pressure readings that were able to be reset by turning the ignition off and on. Temperatures were steady and no idiot light so it lead me to believe it was a reading fault.

With a little help from this site and from the linked YouTube. https://youtu.be/KTEm9c5ANEc

The YouTube instructions on grinding down the crows foot helped immensely as it's a tight fit. Also, I followed the instructions from Rennlist to remove the rear right tire and heat shield. Total work time :20

I just cleaned the connectors... seems like a smart first step. But I wonder, how many owners had a simple cleaning work? And how many had to change the sender unit?

Tried that at first with mine. Light sandpaper, alcohol and electro conductive silicon. No luck on mine.

I got around to replacing the sender yesterday. Cleaning the electrodes on the old unit didn't work. The job to replace the sender wasn't too bad. The recommended claw foot wrench was very helpful. New one hooked up fine and works well.

Also, you don't have to remove the rear wheel at all, although removing the heat shield (2 10mm bolts) made the job so simple a cave man could do it, lol.

PS for those of you who might do what I did, learn from my mistakes. You don't have to unscrew the top leads for the sensor, they just pull off. (I unscrewed one, and on the installation after cleaning broken it clean off). Ordered one from Pelican Parts, order was simple, shipping was fast, and installation took all of 15 minutes the first time.

Just replaced sensor this way. Backed car on to ramps and used crowsfoot from the bottom after disconnecting wires from top. Screwed in new sensor and torqued to 12 ft #. Replaced wires from top. All appears good now. (Old sensor didn't go to zero when ignition turned to 1st click and pegged at 5 when started. New sensor at zero when key at 1st click and normal pressure when started).BTW, set of crowfeet at Harbor freight - $8.00.
