Hey guys, can someone clarify that when the 'CLOSED THROTTLE' module is selected we're looking for the reading to be '1', same as a multimeter to show continuity? Pretty sure my TPS is rooted as I can't get 0.4-0.5v when throttle is closed. Presuming it's a 1 for closed?

Don't know why you're expecting to see "1"?

When the throttle is closed it is in the idle position.

What is the voltage you should set the TPS to at idle?

The output option for that module is either 0 or 1. That's what I'm trying to determine! It should be set to 0.4-0.5v as I mentioned in the first post.

Is it your getting a consistently high figure where ever you set the tps to? if so the issue, it is a very common one, you have a faulty cable line from the ecu to the tps. Again assuming I have understood what your getting at and the tps seems to not get down from a high figure then its a targa drain issue that has corroded a connector inside of the car that the tps cable goes through and is causing a fault on the line as such. I did a tech thread about this and in particular those with automatic gearboxes are more effected by harsh or non gear changes. ( LINK BELOW )

With the engine OFF & the ignition ON & the throttle closed (at idle position) you should see TPS voltage of 0.40V to 0.50V with the usual setting of 0.45V being the average setting.

At full throttle opening, the voltage should be 4.0V.

Thanks Jeff. I'm trying to clarify if when viewing the Throttle Closed gauge on a Consult program, which only has a 0 and a 1 as readings, does the 1 mean the hard idle switch has engaged? At the point where it's just turned to 1 I can only get a reading of 0.3something volts on the TPS voltage gauge?
