TPS and Coil Testing help please?
« on: December 18, 2012, 04:15:37 AM »
Hey guys,
I'm just wondering what is the correct TPS setting i heard it may be half a volt at idle? is this correct? if not how do you actually set the tps and also how can i test my coils? motor is a rb30det with a 25det vct head. cheers(:

what computer are you running? If after market just hook into with with a laptop and configure the tps there. If not then .5v between ecu signal wire and ground with throttle on idle stop.

Thank you! that helped. it was 0.5 flickering on it and just over. just some chipped ecu. at the moment. i'll try something else still not running right

These readings are from a consult printout of my first TPS failure, the replacement TPS. Nissan said that the voltage of the new one was exceptionally good as the voltage is normally a little lower (depressed) and they said I must have got one of the rare good TPS sensors.

 TPS failure voltages as below-

 DEPRESSED : 3.60V
 RELEASED : 0.42V
 RANGE : 3.18V
 SPEC : MORE3.0V

 TPS correct voltages as below-

 DEPRESSED : 4.02V
 RELEASED : 0.44V
 RANGE : 3.58V
 SPEC : MORE3.0V

 Released is no throttle (on idle contact), depressed is to the floor (WOT contact). The idle, WOT contact pins inside TPS on each end of track (0-5V) on circuit board tend to bend over time. As far as I know, on R33 they switched to voltage only (I think was Series 2) and removed idle, WOT contact's. Also you'll notice when TPS is faulty, voltage tends to drop.

Edit: If have a chipped ECU, can use Nistune tuning software + Consult cable + laptop to see when TPS is on idle contact, as idle contact light's up in Nistune tuning software.
