hello all

question about the rb20 tps

I was getting .4v closed and then WOT 4.5v per the aem box.

went inside, came out again 20 mins later and started it back up to continue tweaking the idle and now Im getting
.16 v closed and .48 WOT for my tps

I know I can tune it to eliminate the TPS but I was wondering if there may be something else that happened as it seems kinda wierd for a sensor to just drop like this. imo

Voltage going to tps was 5v as the aem only puts out 5.v for that sensor
all grounds are good.
same voltage values coming out of the tps for WOT and closed
:confused:

thanks !!

sounds like a wiring problem or simply a bad tps.
