My fuel gauge has always been wrong on my 1995 Firebird. When the gauge comes off full, I know that I need to get gas fairly soon for street driving and immediately for track driving.
Yesterday through the use of a scan tool, I also learned that my water temperature reads way too low while also learning that GM has two water temperature senors in the car - one for the ECM and one for the fool behind the wheel. The ECM sensor seems correct and the in-dash water temperature gauge is wrong. Should I be treating these two problems as separate or is it possible that these are related? |

QUOTE (Jon A @ Mar 29 2005, 01:07 PM) The guage in your dash reads coolant right as it comes from the radiator. The sensor for the PCM measures coolant after it has been through the engine. If the two read the same under power then one would surely be broken. If you put an accurate aftermarket gauge in the same spot as the stock gauge, it'll likely read the same as the stock gauge is now. Good information to know. However, with the scan tool for comparative purposes on Saturday, the differences between the two didn't seem linear and the water temp gauge never really reached 180 though the scan tool at one point showed +230 degrees... With no air flow (including pulling the fan relays) sitting on a dyno, would my stock radiator really be able to pull +50 degrees out of the water temperature? |
