Hi all,
My wife's 4Runner (auto) has been stalling/dying very intermittently. I've searched and there seems to be many suggestions to solve this problem. No check engine lights. I hooked up the scanner yesterday, and there are no codes in the history. However, the throttle position sensor indicated a position of 11.9% when closed, and 76% when fully open (this is opening and closing the throttle at the throttle body). Is that right? On all my other cars, the TPS indicates 0% when closed, and 100% when wide open.
I then check the resistance between the appropriate connector pins at the TPS in the closed and open postiions, and the measurements fall within the range in the service manual, albeit on the low end.
Has anyone found this to be a problem, especially in relation to the intermittent stalling problem?
Can just the TPS be replaced, or is it an integral, matched part of the throttle body assy?
If just the TPS can be replaced, is this available as aftermarket (Pep Boys, Kragen, etc), or is a dealer-only part?
Thanks for your patience,
Jim
