2G TPS Question.

[phunny]

I searched and found 1 thread that started off okay then go way off track. Are 2g's supposed to read 0% with no gas pedal given?

Mine does. If it's not supossed to, then mine may not be adjusted correctly.

Mine used to before the 6 bolt swap. Now it reads around 3% when the throttle plate is closed. 3-4% and under should be fine. What is yours reading at closed and WOT?

On a 1G there is a throttle stop switch that will tell the ECU that the throttle is closed no matter what the TPS is saying. So if the TPS is out of spec then the ECU will through a code everytime the throttle closes. I would assume 2Gs are similar.

mine reads 19 at idle and 100 at wot.

i got mine set to zero now. thx guys

What is it at WOT now?

are you reading the throttle % off of an AFC or some sort of logger?

anyway, I'm pretty sure 2G's are supposed to read 0% at idle, and because the closed throttle switch is integrated into the TPS it's adjustment is critical. after swapping in a 1G throttle body, I thought I had the TPS adjusted correctly, but it ended up reading 3% on the logger and was idling at 1500rpm. WOT never goes to 100%, but it doesn't really need to. a misadjusted TPS won't throw a CEL. one time i forgot to plug the connector back in and the car ran okay without any CEL. the only reason I noticed it wasn't connected was because the throttle % on the AFC stayed at zero.

I'll check wot after work, but i use afc and palm pilot to check tps.

I remember reading on the RRE webpage that if your using a logger and safc they wont read the same. One of them will read 0 while the other will read 1, can't remember which one is which though. I know off dsmlink mine reads 1% at idle and 96% at wot.

1gs are supposed to be set and read 10% at idle. If i was you check the voltage value for your TPS with the safc and a logger. Set it to around .045volts.
