Throttle Valve Switch Question, M103
 

Hey All,

I've been chasing down a very specific stall problem (http://www.peachparts.com/shopforum/showthread.php?t=253042) and I was running some preliminary tests before I went full tilt into testing Duty Cycle/EHA/ICV/CPS/etc (following this article: http://www.landiss.com/mixture.htm) and I tested: I got no response from the Dwell Meter when deflecting the air flow sensor plate (big one on top of the fuel distributor, right?). Hmm. So I pulled the Throttle Valve Switch (TVS) connector and tested it as per the FSM:

(Idle Contacts = Pins 1 & 2, Full Load Contacts = Pins 2 & 3.)

These are my findings:
Idle Speed Contacts were as specified in the manual.
Full Load Contacts were showing infinite resistance at all positions (idle, Full & Partial load). :inquisiti

I tested & re-tested this.

Can anyone explain to me what this means? :confused:

My stall can be explained (short version) as only happening when I go "full load" (accelerate hard) and then stop abruptly. I'm assuming that an F-ed up/sticking TVS could cause this, but we all know what they say about assumptions...:rolleyes:

I guess my main question is: Do my test results signify a faulty TVS?

I will be updating all threads related to my SSS when I finally lick this problem.

Thanks!!
