As cylinder head temperature rises, the electrical resistance of the thermistor decreases.<br /> <br /> &#039;&#039;WARNING&#039;&#039; - Do this modification at your own risk.

The chart will provide the correct readouts:<br /> <br /> | Cylinder Head Temperature | Resistance in Ohms |<br /> |---|---|<br /> | Above 20°C (68°F) | Below 2.9kΩ |<br /> | Below 20°C (68°F) | Above 2.1kΩ |<br /> <br /> If the readings are OK here, then replace the ECU. If the readings are out of spec, first check the harness for damage including corrosion and broken wires.<br /> <br /> If the harness looks OK, then you can test the sensor using the chart below.<br /> <br /> [http://xenonzcar.com/z31/SENSORS/CHTS/CHTStroubleshooting2chart.jpg image: CHTS Resistance Chart]<br /> <br /> [[Category:Imported from Xenonzcar]]</div>
