colsy Posted October 2, 2009 Posted October 2, 2009 Hi all, My oil pressure guage is always reading off scale >120psi, its the same when ignition is at pos 2, i.e. to get electrics on, and when engine is running. The oil level is mid way, so its not excessive oil. The car runs sweet, temperature always below mid way and its quiet, so its not blockage. It must be an electrical fault? I only picked the car up last night, drove c.200 miles with no issues, guage at max. how can I check the guage, I guess its a volt meter type using a pressure transducer converted afterward to analogue? I have a multimeter, how do I get to the important terminals, what should I look to register? has anyone had similar problems? Cheers, Col. Quote
Beavis Posted October 2, 2009 Posted October 2, 2009 Sounds like a faulty sender unit to me and will probably want changing. Either that or the guage is faulty. Quote
martinmac Posted October 2, 2009 Posted October 2, 2009 Dont buy any parts you need from Nissan, you can get them a lot cheaper on here. zxtreme has a garage very near you. Quote
colsy Posted October 2, 2009 Author Posted October 2, 2009 Great stuff guys, will look ino it when I get time, where is the sender located? Col. Quote
fatalus Posted October 2, 2009 Posted October 2, 2009 Had exactly same thing. It is the sensor that sits in the oil chamber that is faulty. Costed me 100 euros for that little piece of s##t. Quote
colsy Posted October 2, 2009 Author Posted October 2, 2009 fatalus, where do I find the oil chamber...that might sound like a stupid question...but the first time I saw a 350z engine was this morning when I opened my bonnet to check levels! Cheers. Quote
colsy Posted October 3, 2009 Author Posted October 3, 2009 Anyone know where the sender/oil chamber that fatalus is refering to is llocated? Col. Quote
Beavis Posted October 3, 2009 Posted October 3, 2009 You could download one of the service manuals and look for it http://www.350z-tech.com/zwiki/Service:Index Quote

Beavis Posted October 3, 2009 Posted October 3, 2009 Servce manual download didn't work...I have the zipped folder...but I get an error message saying the folder is empty when I try to extract...anyone had anything similar? No just downloaded the 05 service manual myself to the works pc. Opened fine Section EM page 28. Right by the oil filter. Quote
