S-AFC showing 0% ALWAYS

[93GSXCLIPSE]

Hey guys, well out of nowhere my afc started reading 0% all the time, no matter where the gas pedal is... I didn't hit any bumps or knock the afc over, so I dont think it's a connection...what can you tell me about this? What are possible reasons for the reading.

mine did the same thing when i had my supra except it wouldnt go to 100% throttle even though i was flooring it. I had to reset the safc and it fixed it. Make sure though you write down your settings first

what did you have to do to reset it?

 

[robbo185]

umm you have to go to the part of the safc where you choose like no. of cyl. and stuff like that and the part where its says something like initialize settings you choose yes if i remember correctly. If you go to apexi website and get the manual it will tell you

Have you checked your tap at the ECU for the TPS and make sure that didn't fall out?

Choose 'initialize' to reset your SAFC. Also check your actual TPS plug (black plastic thing on the throttle body) and make sure that the harness is clipped on. For some reason DSMs always miss those forsaken clamps that hold the plug on.

Before you initialize anything check the connectors as suggested and go into the etc menu and sensor check. That will show you the raw voltages the SAFC is seeing. If it's 0v there or doesn't move when you change the throttle position then shart looking at the TPS and wiring.
