Problem with TPS voltage These electronic/computer/fuel injector cars can be a bit of a mystery. It's like a series of dominos, or a game of janga- everything trips into another thing... ANYWAY, my car failed smog because of high idle and timing at 16 degrees BTDS instead of 6(!). I set the timing correctly, but when I checked the TPS I found an issue. There is only one machine screw holding the TPS in place- the bottom one has been sheared off. Now I know the voltage should be 0.54v, +/- 0.07 something. Even when loosening the one screw and moving the TPS as far as it will go, I can not get the voltage below 0.66v. If the outer limit of the tollerance is 0.61 or so, is my voltage worth sweating about- and will it cause any other issues? |

Without the IAC and warm... it should be a low RPM. Neighborhood of 500-600RPM. If it's not, the IAC wouldn't be able to bring the RPM down. Do you have any kind of scan tool that you can see what the IAC counts are? You want to IAC to control the idle... While talking about the IAC, a good cleaning of it and the passage way could be in order as well. |
