Al Downs Posted September 21, 2013 Report Share Posted September 21, 2013 Anybody ever see this before? 2070 rpm, left egt 852, right egt 2038, left cht 175, right cht 190. This just happened today and only at low rpm. Temp drops to normal at higher rpm. Link to comment Share on other sites More sharing options...
Roger Lee Posted September 21, 2013 Report Share Posted September 21, 2013 Hi Al, Sounds like a poor connection on the high EGT wire. These are very sensitive to resistance and low rpm on the grounds and wires can cause this then when you apply throttle it goes back down, evidently because the resistance changes.I see this off and on with the oil temp grounding. Either way you know it isn't real. Check the EGT plug in at the end of the braided line. The right one is in the instrument panel on the passenger side by the grounding block. While you are there might as well check the ground tightness for all on the bolt that protrudes through the firewall. It doesn't sound like a bad probe because it straightens out on throttling up.

Al Downs Posted September 23, 2013 Author Report Share Posted September 23, 2013 Roger I cleaned both wire connections but it is still the same. When I unplug the yellow wire it goes to normal but I shut down and power up again it reads 2034. Do you think it could be the sensor? Link to comment Share on other sites More sharing options...
Jim Posted September 23, 2013 Report Share Posted September 23, 2013 If you can, swap the connections to the two probes. If the indication stays on the right side, it's the dynon or the cabling between the dynon and the connection point. If the indication moves to the left side, it's the probe or the wire between the probe and the connection point, Link to comment Share on other sites More sharing options...
Roger Lee Posted September 23, 2013 Report Share Posted September 23, 2013 Do as Jim suggest. Link to comment Share on other sites More sharing options...
gisurvey Posted September 29, 2013 Report Share Posted September 29, 2013 If you didn't find the problem yet, order a new sensor and change it, is more simple and fast this way for an amateur (like me for example). If everything is fine - that's all, if not - you have a spare one, and must continue to investigate. Could be the wires and not the sensor itself, and if is so, is more tricky to find the exactly problem because you'll have random results after various tests/movement of wires.

Al Downs Posted October 7, 2013 Author Report Share Posted October 7, 2013 Thanks everyone. I replaced the sensor and is all good again. Link to comment Share on other sites More sharing options...
Tip Posted October 25, 2013 Report Share Posted October 25, 2013 Hi Al, what's the part number for the right EGT probe? Link to comment Share on other sites More sharing options...
