Low oil pressure on gauge - false reading

Recommended Posts

Hi,

 

My 06 JDM 350 is showing low/nil oil pressure on warm idle. Mechanic has checked with his mechanical gauge and thankfully pressure is ok so must be a false reading. It's full of oil and new filter.

 

Its got lots of mods including a trust oil cooler so mechanic isn't sure which bit to replace so he took some photos which are below.

 

The gauges appear to be aftermarket and the oil pressure is in bar..

 

Any ideas what I should try first?

 

Thank you in advance

 

Kev

Could be faulty gauge or a dodgy oil pressure switch.

 

Both easy to test or swop out, however if your mechanic does not know this then best to take to someone who knows there way around a 350Z.

 

To test the gauge just take the wire off the oil pressure switch and take to ground.

 

The gauge should read maximum.

 

if this is the case then the gauge is okay so probably the oil pressure switch.

 

Both in stock if required.

Thanks Alex

 

It's just he thinks the parts look different to the one's he researched so not sure if they are JDM ones.

 

Great, what is the cost on both of those? Can I just put a Nissan oil pressure gauge in alongside the other aftermarket ones which seem to be working?

In answer to your gauge question, An OEM gauge may work in tandom with your aftermarkets but that will all depend on how they are all hooked up.

It may be simpler just to replace the complete 3 gauge cluster with an OEM unit which I also have in stock.

I can offer you a brand new or fully working preowned oil pressure sensor.

The gauges will be fully working preowned.

let me know what parts you require once you have had an informed diagnoses.

Best to drop me a PM as I may miss a reply here.
