scan tools, sensor readings?
(04 Cavalier)
I have a Gore Proscan OBD2 interface module, which lets you display various sensor readings on a PC. Some of these (eg, rpm, TPS, ...) work fine. But, ... (1) Some sensors, which I know the PCM reads (eg, fuel tank pressure), seem not available for display. (2) Some sensors that the software shows as available (eg, fuel level) seem not to show any readings. It could be me, though I'd be the last to know that. I would appreciate any insight on the availability of sensor data on various scan tools. The vendor web sites seem to list the obvious ones, and conclude with "And more ...". Is it just a matter of how much you pay for the scan tool? ISTM, once you have the OBMD interface and user screens done, the effort to support additional sensors would be minimal. Would the PCM would hold back data the OBD? ... Thanks |

There are differences even in the pro/dealer level tools. In your case I know the OTC/SPX Genisys shows the info you're looking for. Not sure what PC units show with the exception of actual dealer level units. Ford IDS, GM MDI, Chryslers StarMobile will show far more than any generic units will. -- Steve W. |

The AutoEngenuity software I have for Windows was $1200.00 and will show all modules and all sensors. "Enhanced manufacturer support" costs a lot more than "Generic OBD-II" which it looks like you have. Smoke machines are still $1000 last I looked too, which is essential for EVAP leaks you can't see with just a flashlight (broken hose e.g). GW |

I had an EVAP class instructor mention that once and forgot all about it. If anyone has done that, the step-by-step would be a great thread/page/video for the home-gamer. GW |

I have a friend who could really use a smoke machine, but doesn't have $1K to spend on new equipment at the moment. (and he's my friend, but I don't like him THAT much.) nate |

Basically the hardest trick is getting the smoke through the system without hurting anything, for that you need to regulate the air down a lot. http://www.youtube.com/watch?v=HbkGhUov74Q And for one that is SUPER cheap.... http://www.youtube.com/watch?v=HRiK2HEA3QQ -- Steve W. |
