We've pretty much given up on attempts to repair the stock coolant temp gauge & sensor system. Have swapped out the instrument cluster, replaced the sensor and walked the wire. Still pegging max high with a steady flashing light, but the thermal laser gun reveals a normal temp system. There was a posting recently on "slime" affecting the level sensor in the pressure tank, and I plan to share that with the tech. I suppose that would only affect the blincking light anyway, not the temperature reading. The tech working on it has found a completely independent (of the stock system) aftermarket coolant temp gauge and sensor and he plans to install that over the next two days. One thing is unanswered in my mind. Does the stock sensor give temperature readings to the ECU? I'm wondering if this is one of the reasons why my fuel economy has dropped from 18-19 to 16-17, i.e. running rich. Furthermore, if the ECU does get data from the stock system, how will the aftermarket system get tied into the ECU? I haven't talked to the tech about this yet and wanted to get the ideas of the list. Thanks, Anthony'89 Syncro GL 2.1 (Hidalgo) |
