The gauge on my diesel always read too cool until I replaced the corroded connector. Otherwise, maybe the sensor is failing when it gets to a certain temperature (a cracked connection + thermal expansion?) or maybe it's losing its ground connection somehow when the engine gets hot. There's only so many things it could be. You might try grounding the connection to the sensor some time when the gauge is acting up. If it doesn't go to full hot then the gauge or wiring is at fault, if it does than the sensor, sensor ground, or connection between the sensor and the wiring is bad. -- David Brodbeck, N8SRE '82 Diesel Westfalia '94 Honda Civic Si |
