Hi all just been surfing and found a site that sells the 300zx throttle position sensor at a decent price too.

Yeah they are good, i bought my O2 sensors from them for peanuts. And I know they work well coz im getting a wideband reading of 13.7-14.7afr when cruising ;) well worth it i recon. They pulse nicely on the consult too.

Did you buy the universal o2's on the same page as the tps jimmy...

no i bought the ones with the connector so i didnt have to start cutting wires. Im pretty sure it was that site. They have an Ebay page too.

Not to worry anyone but the pic of the TPS doesn't look like the one fitted to the Z32 ... Could just be a stock photo but caveat emptor ...

what does caveat emptor mean.........??

buyer beware?

Do these tend to go faulty then??

They do but it is quite random. It is usually one of the connectors that goes first and quite often cleaning the contacts sorts a lot of problems. The problem is that the TPS is attached to the side of the upper plenum which gets bloody hot.

 

And yes, "caveat emptor" means buyer beware ... ;)

So what problems would you have if it was faulty??

Can be a number of symptoms but generally speaking you'll have one or more of the following:

 

rough idle

high idle

hesitation

stalling when coming to a stand-still

 

Sometimes cars exhibit these problems and a ConZult check reveals that the TPS if functioning properly. The next port of call would then be to have a look at the throttle balance (or whatever it's called). Basically, take the intake pipes to the throttle bodies off and see whether the two butterfly valves open at the same time. I've seen cars where one butterfly valve was practically completely open before the other one started to move.

 

Again, there are more symptoms but the ones listed above are the most common.
