Oil Pressure Gauge

I have a 997.1 S.

 

Recently the oil pressure readings have become abnormal.  Rather than indicating ~ 3 at idle and 5 at high rpm, it shows 5 all the time.  With electric power off, the reading is 0.  It jumps to 5 with electrical power on before starting the engine.

 

Is this a failure mode for the pressure sensor?

What is considered normal behavior (indications) oil pressure gauge? 

 

I am a new 2006 C2S owner and the oil pressure seems to be  pinned at 5 once I start the engine. 

I have seen it drop to 3 when coming to stop at idle BUT it doesn't seem consistent.

 

I will gave to go back and check - have not noticed the indication with just electric.

 

It seems strange that normal (constant speed) driving would have it pinned at top of gauge

Welcome to RennTech :welcomeani:

Common problem, usually the sending unit going goofy.  Easy DIY.

Just tested it with key turned to on (before start) and engine cold the gauge indicated about 3.

Sounds like it is time to replace the sending unit.  

Thanks.
