TPS faulty?

[Adash=P]

Noticed a bit of an issue on my JZX100. According to my Apexi SAFC Neo, the TPS isn't registering anything until I go past about 10% throttle. It was working fine when I installed it months ago and I tried another TPS and its the same story.

Is there a way of testing it to see if its faulty? I'm about to get it tuned and I don't want things going pear shaped.

can you calibrate the SAFC?

Yeah I did that when I installed it and I tried resetting it to no avail. With the throttle completely closed it reads .6V when it should be 0.

You should be able to re learn the safc to the tps.

get an multimeter, a feeler guage and set the TPS on the throttle body. Then redo the SAFC.

You wont necessarily have 0v from the TPS with closed throttle.

Unlike all the other TPS I've seen before, this one has no adjustment.
