Exhaust temp sensor relocation???

[CRS]

Been reading a few posts that have mentioned moving the exhaust water temp sensor. Where are you moving it to,why and with what benefits?

Chris, you actually don't remove it. You relocate it from the waterbox and strap it to one of the coolant hoses going to the coolant tank.

The theory is that if you have a modded waterbox it evacuates water more freely which could cause the sensor to register hot which in turn causes the ECU to richen up the fuel mixture to cool things down.

All the temp sensor needs is a constant hot source and the coolant hose works great for this. I just used a couple of zip ties to secure it to the hose.

So the people that may be running lean as some suspect could benift from the WB mod??

With the sensor on the coolant hose would the alarm still go off if the ski was overheating.

I don't think so. If the sensor registers hot it richens the mixture up and this is not conductive of good performance.

No it wouldnt!

Keep in mind this is the exhaust temperature sensor. Not the engine coolant temperature sensor.

Yes, mine has gone off once since I moved the sensor to the coolant tank hose. H-temp on the display.

There are two temp sensors. One for the exhaust and one for the engine. If you got an H temp and the exhaust temp sensor was relocated it was your engine running hot.

I don't know why the engine would get hot with the 158* thermostat
unless the water pump impeller was damaged, or some kinda internal cooling passage restriction. It's only done this since the motor came out for debris removal. hummmm... where is the other sensor located at?

also it will only go off after extra long WOT runs. I get no error codes.
If I let it idle for about a min it stops beeping, and back to normal. Maybe I need to get a manual eng temp guage now.
