Just wondering if it's normal for the S4 TPS to have such a short range of motion. In the first pic, throttle is almost closed (cold engine so it's not entirely closed).



I've noticed that past about 1/3rd throttle, the plunger is already extended to its fullest. Is this normal? (I'm reading 4.13ohm when it's fully extended)

 

yeah, thats one of the reasons so many guys use the pressure sensor signal for tuning with shitty ol' s-afc's. Because the TPS will read 100% at 1/4 throttle.

All normal

 

it is a short sweep sensor(about 30% throttle registers as full throttle to the ECU), it is normal.

 

LOL. Thanks.
