The problem i found with my tsp was it did idle to high at .45 idles perfectly at .47 but idles badly at .55 so .55 may just be to high for yours. Also i set mine with the engine not running with just the ignition turned on by using my greddy informeter :lol: i knew it would come in handy one day
Adjustment : This can either be done manually (with a multimeter) or by plugging into the Consult Port with a laptop and reading it straight off the screen. If using a multimeter it must be done with IGN ON (engine does not need to be running) and the connector fitted to the TPS. You'll need nice sharp multimeter probes to pierce the insulation on the wires - it often pays to give them a quick sharpen with a file/grinder etc. Carefully probe the 0V wire (Black) and the signal wire (White). Don't use chassis GND. With throttle closed you should be seeing 0.5V. The spec is 0.35V to 0.65V but it's nice to have it right in the middle. Adjustment is done by loosening the 2 screws that mount the TPS - NOT by using the throttle stop screw.
TPS Closed :Another handy thing to check is that the ECU is actually seeing "TPS Closed". It monitors the TPS position and when it's in a certain range (normally 0.35 to 0.65V) it assumes the throttle is closed. This triggers a flag in the ECU which makes it go into idle mode. You can monitor this via the Consult port using Datascan. If your throttle is closed but the ECU doesn't see it then stable idle will be impossible to achieve.
Check TPS function : While you're playing with the TPS it's a good idea to check it across the range. Slowly open the throttle - you should see the voltage increase smoothly to just over 4V. If you see any sudden changes (to 0V or 5V) then I'm afraid she's knackered and it's off to Mr. Nissan with you. The Consult Port is extra handy for doing this check as you can log the TPS value while you drive the car - and then check the trace for any drop-outs later.
Not sure what else to look at! managed to get my laptop to read consult today, was giving my win error 2
but i was connecting it all to the computer than starting the program, now when i start the program and then attatch the consult it seems to be working.
the car turns over but fires about once in a cycle of five.
As the car was running ok before i put new O.E ht leads on i am scratting me head now
right got my conzult to work for the first time since i have had it
Anyway how does the bloody thing work
I have the following values i knew my tps was 0.44, but is the maf voltage supposed to be 0.48
And to read the Diagnostic trouble codes do you just press the button on the ECCS page as when i do it just comes up as a blank window
